ENERGY SERIES: What about the Air Conditioning System? | As you begin the process of selecting the most efficient air conditioning system for
your home, investigate the critical issues of system size, placement, installation,
and contractor experience. Your goal is to obtain an efficient system by: sizing
the system for the specific cooling load of your home; selecting and properly
installing the thermostats or controls; designing a ductwork system to deliver the
correct amount of conditioned air to each space; and sealing and insulating all
ductwork. |

ENERGY SERIES: What About Using Ceiling Fans? | Ceiling fans create a breeze, so room occupants feel cooler and more comfortable. With
a ceiling fan running, you can raise the thermostat setting by 2 to 4 degrees during
the cooling season with no reduction in comfort. Increasing the room temperature by
even two degrees can cut your cooling costs 4 to 6%. |
Mar 26, 2020 | 2901-9002 (BSE-290NP) | ||
ENERGY SERIES: What About the Ductwork? | Air distribution or duct systems are designed to supply rooms with air that is
“conditioned”—that is, heated or cooled by the heating, ventilation, and air
conditioning (HVAC) equipment—and to recirculate or return the same volume of air
back to the HVAC equipment. Your duct system has two main air transfer systems: 1)
supply, and 2) return. The supply side delivers the conditioned air to the home
through individual room registers. The return side picks up inside air and delivers
it to the air handler of your central system where heat and moisture are either
removed or added and then delivered to the supply side. All of the air drawn into the
return duct(s) is conditioned and should be delivered back through the supply
registers. |

Energy Series: What about Fluorescent Lighting? | May 1, 2009 | 2901-9004 | |||
ENERGY SERIES: What about the Heating System? | The efficiency of a gas (natural or propane) or oil furnace is measured by the Annual
Fuel Utilization Efficiency (AFUE), which describes the heat produced from the energy
used. This rating takes into consideration losses from pilot lights, start-up, and
stopping. For example, a furnace with an AFUE rating of 80 converts 80% of the fuel
it burns into usable heat. New furnaces usually rate in the mid-70s to low 80s,
whereas older furnaces will be in the 50s or 60s. ENERGY STAR® qualified oil and gas
furnaces have annual fuel utilization efficiency (AFUE) ratings of 83% and 90%, or
higher, making them up to 15% more efficient than standard models. Unlike the Seasonal
Energy Efficiency Ratio (SEER) and Heating Season Performance Factor (HSPF) ratings,
the AFUE does not consider the unit’s electricity use for fans and blowers. |
May 12, 2020 | 2901-9005 (BSE-292NP) | ||
ENERGY SERIES: What about Insulation? | Insulation is rated in terms of thermal resistance, called R-value, which indicates
the resistance to heat flow. Although insulation can slow heat flow—conduction,
convection and radiation—its greatest impact is on conduction. |
Apr 14, 2020 | 2901-9006 (BSE-293NP) | ||
ENERGY SERIES: What about the Laundry Area? | The laundry room can be a big consumer of energy—more than 1,000 kilowatt-hours (kWh)
a year—and water—and a big producer of unwanted heat and humidity in the summer. It
makes good sense to think about both the location and the appliances in it if you want
to run an energy-efficient laundry. And there are new washers and dryers on the market
now that make it easier than ever to do so. |
Mar 25, 2020 | 2901-9007 (BSE-294NP) | ||
ENERGY SERIES: What about Mold? | Mold has received a lot of attention of late because of high profile lawsuits and television news broadcasts that have highlighted the potential hazards and liabilities associated with indoor mold. What is mold? Molds, along with mildews, yeasts, and mushrooms, all belong to the kingdom fungi. Fungi are unicellular or multicellular organisms that primarily use absorption as a means to obtain energy from their environment, unlike green plants, which use chlorophyll to obtain energy from sunlight. The term “mold” describes unwanted visible fungal growth. “Mildew” is fungi that grows on fabrics or that causes plant disease. The term “yeast” is fungi that are unicellular when cultured. |
Mar 26, 2020 | 2901-9008 (BSE-295NP) | ||
ENERGY SERIES: What about the Water Heater? | Heating water is the third largest energy expense in your home, after heating and cooling the entire space; and, it can account for 15-25% of your utility bill. It’s not hard to see why a family of four, each taking a 5-minute shower a day under inefficient showerheads, can use 700 gallons of water in a week representing a 3-year supply of drinking water for one person! There are several ways to cut down the amount you spend on heating water: a) insulate your water heater and pipes; b) reduce the amount of hot water you use; and c) turn down the thermostat on your water heater. |
Mar 24, 2020 | 2901-9009 (BSE-296NP) | ||
ENERGY SERIES: What about Windows? | The National Fenestration Rating Council (NFRC) offers a voluntary testing and certification program for thermal performance for windows and residential door products with glass. The NFRC does not conduct structural characteristics, such as impact-resistance, but rather serves as a complementary program that can test the whole window (including frame) for the following characteristics: U-Factor, Solar Heat Gain Coefficient (SHGC), Visible Transmittance, Air Leakage, and Condensation Resistance (see sample NFRC label) . |
Mar 20, 2020 | 2901-9010 (BSE-297NP) | ||
ENERGY SERIES: What Are the Differences Between Mobile and Modular Homes? | Mobile and modular homes are factory-built and generally differ in how much of the construction occurs at the factory. The greater the work at the factory, the less labor is needed where the home will be located. |
Mar 20, 2020 | 2901-9011 (BSE-298NP) | ||
ENERGY SERIES: What Can Builders Do to Help Prevent Moisture Problems in New Construction? | Buildings should be designed and built to provide comfortable and healthy levels of relative humidity. They should also prevent both liquid water from migrating through building components and water vapor from being trapped in building assemblies, like walls. |
Feb 26, 2020 | 2901-9012 (BSE-299NP) | ||
ENERGY SERIES: What Does the Shape of the House Have to Do With Energy Efficiency? | In a home, heat energy is transferred among all materials and substances that are of different temperatures—within the building materials, inside the building itself, and outside the building envelope. The term “building envelope” refers to all of the external building materials, windows, and walls that enclose the internal space. Heat moves only when there is a difference in temperature, and it always moves from the warm side to the cool side. Heat will continue to “flow” until any touching materials reach the same temperature. However, we usually want the inside of a home to have a different temperature from the outside. |
Feb 12, 2020 | 2901-9013 (BSE-300NP) | ||
ENERGY SERIES: Estimating Appliance and Home Electronic Energy Use | If you're trying to decide whether to invest in a more energy-efficient appliance or if you'd like to determine your electricity loads, you may want to estimate appliance energy consumption. |
Feb 26, 2020 | 2901-9014 (BSE-301NP) | ||
ENERGY SERIES: What about Appliances? | When shopping for appliances, remember that there are actually three prices to consider. The first is the one everyone considers: the purchase price. The second price is for repairs and maintenance. The third price is often forgotten, but equally important: the operating cost of the appliance. Operating cost depends on the cost of fuel (kilowatt-hour, cubic foot, therm, etc.) in your region, how much you use the appliance as well as the way you use it, and the overall energy efficiency of the appliance. Operating cost shows up on your utility bill each month for the life of the appliance. Your refrigerator, for example, may operate effectively for 15–20 years and your dishwasher for about 10 years. You'll need to consider how any given appliance will affect your utility usage. |
Feb 25, 2020 | 2908-9015 (BSE-302NP) | ||
ENERGY SERIES: What about the Bathroom? | Did you know the U.S. Environmental Protection Agency (EPA) estimates that private homes
account for more than 20 percent of the energy and about 55 percent of publicly supplied
water consumed in the United States? We all know that we can save water if we just turn off
the tap while brushing our teeth. We also know that when we reduce the amount of hot water
used we also decrease the energy needed to heat the water. But, did you know there are
products that can help you save water even when you have to use water? |
Feb 12, 2020 | 2908-9016 (BSE-303NP) | ||
ENERGY SERIES: What about Caulking and Weather-Stripping? | The greatest source of wasted heating and cooling energy in a home is air leaks. If you have
a pair of 6' 8" exterior doors in your home that do not have weather-stripping, you can
easily have an opening of ¼" all along the edge where the doors meet. This ¼" gap adds up to
a 20-square-inch opening to the outside. If you saw a hole this big in your wall, wouldn’t
you want it fixed? |
Mar 26, 2020 | 2908-9017 (BSE-304NP) | ||
ENERGY SERIES: What about Dishwashers? | It may come as a surprise that washing a load of dishes in the dishwasher uses less water
than doing the same number of dishes by hand. (Dishwashers also do a better job of killing
germs, because they use hotter water than you would normally use if washing by hand.) For
each cycle, an ENERGYSTAR qualified dishwasher model uses about 4 gallons of water; a
non-qualified model uses about 6 gallons. |
Feb 24, 2020 | 2908-9018 (BSE-305NP) | ||
ENERGY SERIES:What about House Design and Room Location? | While a good heating, ventilation, and air conditioning (HVAC) system and other energy saving
features can provide you with a comfortable indoor environment, it is even more efficient to
prevent heat from entering the house in the first place. By designing a house with the right shape
and orientation, and strategically locating rooms, you can save on energy costs for cooling and
heating. If renting or purchasing, look for these same features in an existing home. |
Feb 17, 2020 | 2908-9019 (BSE-306NP) | ||
ENERGY SERIES: What about Moisture? | Air is made up of a mixture of gases including oxygen, nitrogen, and carbon dioxide. It also contains
water vapor—water in the form of a gas. The temperature of the air determines how much water vapor
it can hold: warm air can hold more than cool air. When the air is saturated, it cannot hold any
more, and any extra water vapor will condense into liquid form. |
Feb 24, 2020 | 2908-9020 (BSE-307NP) | ||
ENERGY SERIES: What about Radiant Barriers? | Reflective insulation systems are made from aluminum foils with a variety of backings such as roof sheathing, kraft paper, plastic film, cardboard, bubble wrap, etc. The resistance to heat flow
depends on the direction of heat flow with this type of insulation most effective in reducing
downward heat flow and requiring an air space next to the reflective side. Reflective systems are
usually located between roof rafters, floor joists, or wall studs. Reflective insulation placed in
walls or on the attic floor must be perforated to allow water vapor to pass through it. |
Feb 14, 2020 | 2908-9021 (BSE-308NP) | ||
ENERGY SERIES: What about Refrigerators and Freezers? | Your refrigerator is the only appliance that works continuously in your home 24 hours a day. In most
households, the refrigerator is the single biggest energy consuming kitchen appliance. According to
ENERGY STAR, replacing a refrigerator bought in 1990 with a new ENERGY STAR qualified model can save enough to pay for lighting an average household for nearly four months. |
Feb 14, 2020 | 2908-9022 (BSE-309NP) | ||
ENERGY SERIES: What about the Roof? | Roofing is more than shingles, tile, or metal. A roof system consists of several components, properly
assembled to provide the appropriate shelter for a structure. These include structural elements,
moisture barriers, and possibly insulation or ventilation. |
Feb 12, 2020 | 2908-9023 (BSE-310NP) | ||
ENERGY SERIES: What about Ventilation? | “Ventilation” is “the natural or mechanical process of supplying conditioned or unconditioned
air to, or removing air from, any space.” “Infiltration” is the uncontrolled leakage of air
through cracks and gaps in the building envelope, especially around windows and doors.
Infiltration deals with uncontrolled situations. In our homes we want to be able to control
air movement. |
Feb 12, 2020 | 2908-9024 (BSE-311NP) | ||
ENERGY SERIES: What is the Whole-House Systems Approach to Energy Efficiency? | The whole-house systems approach looks at the
entire house as an energy system with
interdependent parts. Like a human body, when
one part functions poorly it affects the
performance of the entire system. For instance,
the benefits of an energy-efficient air conditioner
are lessened when a duct system leaks, windows
don’t close tightly, the attic is uninsulated, and
humid summer breezes are drifting in under the
door. |

Lighting and Marking Recommendations for Animal-Drawn Carriages, Buggies and Wagons | Horse-drawn buggies or wagons and other animal-drawn carriages have been used by
the Plain Communities as the primary means of transportation for generations.
Equestrian sports and tourism business enterprises have also increased the number
of horse-drawn carriages on streets and highways.

Preparing for an Emergency: The Smart Thing to Do | Preparing for emergencies is not new. Your grandparents probably have extra supplies, such as: soap and shampoo in the bathroom closets, onions and potatoes stored in the basement, and canned goods on pantry shelves in their home. They understood the value of having a little extra on hand in case of emergencies. |

Best Management Practice Fact Sheet 14: Wet Ponds | Wet ponds are ponds designed to retain water through storage. They provide treatment through settling and biological uptake. They can also attenuate peak flows and provide flood and streambank protection. This fact sheet describes wet ponds and their benefits and limitations. |

Best Management Practice Fact Sheet 2: Sheet Flow to Open Space | Sheet flow to open space (SOS) is a group of best management practices (BMPs) designed to disperse concentrated runoff to sheet flow into filter strips or a riparian buffer. An SOS reduces runoff volume and associated sediment and nutrients that are carried with it (see figure 1). It is used as a stormwater treatment practice in both urban and rural areas. This practice is often used after another treatment practice to disperse or eliminate runoff. In a few cases, an SOS can be used as a pretreatment to remove small amounts of sediment via a vegetated filter strip — prior to a bioretention device, for example. |

Best Management Practice Fact Sheet 3: Grass Channels | Jul 1, 2020 | 426-122 (BSE-271P) | |||
Best Management Practice Fact Sheet 4: Soil Restoration | Soil restoration (SR) is the technique of enhancing
compacted soils to improve their porosity and nutrient
retention. It includes biological (worms) and mechanical
aeration, mechanical loosening (tilling), planting
dense vegetation, and applying soil amendments.
Soil amendments involve the spreading and mixing of
mature compost into disturbed and compacted urban
soils (see Figure 1). |
Jul 14, 2020 | 426-123 (BSE-272P) | ||
Best Management Practice Fact Sheet 5: Vegetated Roofs | A vegetated roof (VR) is a best management practice
(BMP) that reduces stormwater runoff and pollution.
Vegetation and media create a permeable system on
a previously impervious surface. The VR intercepts
rainfall and filters runoff while reducing the volume
and velocity. Vegetated roofs consist of a waterproofing
barrier, drainage system, and engineered growing
media. There are two types of VRs: intensive and
extensive. Intensive vegetated roofs are deeper and
heavier, while extensive vegetated roofs are shallower,
lighter, and more common (see Figure 1). The type of
VR determines the amount of maintenance necessary to
maintain the vegetation. |
Jul 14, 2020 | 426-124 (BSE-273P) | ||
Best Management Practice Fact Sheet 6: Rainwater Harvesting | Rainwater harvesting (RWH), also known as rainwater
harvesting systems or cisterns, are devices that intercept,
divert, store, and release collected roof runoff
from rainfall for later use as an alternative water supply
(see figure 1). RWH can also be designed to provide
runoff reduction benefits. Therefore, it is classified as
a best management practice (BMP) for treatment of
urban stormwater. Because of its dual purpose and
benefit, RWH is often classified as a sustainable urban
BMP. |
Jul 1, 2020 | 426-125 (BSE-274P) | ||
Best Management Practice Fact Sheet 7: Permeable Pavement | Permeable pavement (PP) is a modified form of asphalt or concrete with a top layer that is pervious to water due to voids intentionally created during mixing. PPs
include pervious concrete, porous asphalt, and interlocking concrete pavers. These materials are used as stormwater treatment practices in urban areas. They are used in place of traditionally impervious surfaces to allow infiltration and storage, thus reducing runoff
(see figure 1). |
Jul 1, 2020 | 426-126 (BSE-275P) | ||
Best Management Practice Fact Sheet 8: Infiltration Practices | Infiltration practices provide temporary surface and/or
subsurface storage, allowing infiltration of runoff into
soils. In practice, an excavated trench is usually filled
with gravel or stone media, where runoff is stored in
pore spaces or voids between the stones (see figure
1). These systems can reduce significant quantities of
stormwater by enhancing infiltration, as well as provide
filtering and adsorption of pollutants within the
stone media and soils. Infiltration practices are part of
a group of stormwater treatment practices, also known
as best management practices (BMPs) |
Jul 1, 2020 | 426-127 (BSE-276P) | ||
Best Management Practice Fact Sheet 9: Bioretention | A bioretention cell, or rain garden, is a best management
practice (BMP) designed to treat stormwater runoff
from roofs, driveways, walkways, or lawns. They
are a shallow, landscaped depression that receives and
treats polluted stormwater with the goal of discharging
water of a quality and quantity similar to that of a forested
watershed (figure 1). |
Jan 27, 2020 | 426-128 (BSE-277P) | ||
Best Management Practice Fact Sheet 10: Dry Swale | A dry swale (DS) is a shallow, gently sloping channel
with broad, vegetated, side slopes. Water flow is
slowed by a series of check dams (see figure 1). A DS
provides temporary storage, filtration, and infiltration
of stormwater runoff. Dry swales function similarly to
bioretention, and are comparable to wet swales; however,
unlike a wet swale, a DS should remain dry during
periods of no rainfall. A DS is an engineered best management
practice (BMP) that is designed to reduce pollution
through runoff reduction and pollutant removal
and is part of a site’s stormwater treatment practice
(see figure 2). |
Mar 5, 2020 | 426-129 (BSE-278P) | ||
Best Management Practice Fact Sheet 11: Wet Swale | A wet swale (WS) is an engineered, best management
practice (BMP) arranged in a straight line that is
designed to reduce stormwater pollution. A WS consists
of a shallow, gently sloping channel with broad,
vegetated, side slopes and slow flows (see figure 1).
Wet swales typically stay wet because the bottom of the
swale is below the water table. This is done to encourage
the growth of wetland vegetation, providing water
quality treatment similar to a natural wetland. This
stormwater treatment practice also functions as part of
the stormwater conveyance system. Wet swales have a
relatively low capital cost; however, maintenance can
be is intensive and expensive when compared to other
BMPs. |
Mar 5, 2020 | 426-130 (BSE-279P) | ||
Best Management Practice Fact Sheet 12: Filtering Practices | A stormwater filtering practice (FP) treats stormwater
runoff by passing it through an engineered filter media
consisting of either sand, gravel, organic matter, and/
or a proprietary manufactured product, collecting it in
an underdrain, and then discharging the effluent to a
stormwater conveyance system. FPs are stormwater
treatment practices that are often obtained from the
marketplace due to unique proprietary technologies
(see figure 1). |
Mar 5, 2020 | 426-131 (BSE-280P) | ||
Best Management Practice Fact Sheet 13: Constructed Wetlands | Constructed wetlands are a series of ponds with varying depths that treat stormwater using wetland processes. In terms of biological activity, wetlands are extremely productive; and thus constructed wetlands can provide significant water quality treatment to urban runoff. This fact sheet describes these benefits, and provides guidance on their design and limitations. |
Jan 22, 2020 | 426-132 (BSE-281P) | ||
Best Management Practice Fact Sheet 14: Wet Ponds | Wet ponds are ponds designed to retain water through storage. They provide treatment through settling and biological uptake. They can also attenuate peak flows and provide flood and streambank protection. This fact sheet describes wet ponds and their benefits and limitations. |
Jan 22, 2020 | 426-133 (BSE-282) | ||
Best Management Practice Fact Sheet 15: Extended Detention Ponds | Extended detention ponds (EDs) are dry detention ponds
that provide 12 to 24 hours of runoff storage during peak
runoff events (see figure 1). Releases from the ED ponds
are controlled by an outlet structure. During a storm
event, as the discharge restriction is reached, water backs
up into the ED pond. The pool slows flow velocities and
enables particulate pollutants to settle. Peak flows are
also reduced. ED ponds have the lowest overall pollutant-
removal rate of any stormwater treatment option,
so they are often combined with other upstream, lowimpact
development (LID) practices to better maximize
pollutant-removal rates. Due to their placement at the exit
point of the watershed, ED is often the last opportunity
to treat stormwater before it is discharged to a stream.
Because of its low treatment performance, an ED should
be viewed as the treatment option of last resort. |

Nozzles: Selection and Sizing | This fact sheet covers nozzle description, recommended use for common nozzle types, and orifice sizing for agricultural and turf sprayers. Proper selection of a nozzle type and size is essential for correct and accurate pesticide application. The nozzle is a major factor in determining the amount of spray applied to an area, uniformity of application, coverage obtained on the target surface, and amount of potential drift. |

Using Tractor Test Data for Selecting Farm Tractors | The test reports published by Nebraska Tractor Test Laboratory (NTTL) can be extremely useful for selecting tractors or for comparing the performance of different makes and models of tractors. For example, when farmers are in the market for a tractor, the performance data in the NTTL reports can be used to select a tractor that will meet their needs. These reports can also serve as an effective tool for making tractor sales. Dealership personnel can use the performance data to compare their products to those of their competitors. |

Predicting Tractor Diesel Fuel Consumption | Ability to predict tractor fuel consumption is very useful for budgeting and management. The objective of
this factsheet is to develop relationships using field
measurements and Nebraska Tractor Test Laboratory
results to estimate tractor fuel consumption. Using
these equations, farmers can estimate and compare the
fuel consumption for different operating and loading
conditions. |

Preventing Secondary Injuries in Agricultural Workplaces | The intent of this fact sheet is to reduce the number of secondary injuries by familiarizing the readers with secondary injuries and the steps they can adopt
to minimize them. In addition to identifying common secondary injuries and the most vulnerable groups, the publication discusses steps that can be taken to prevent such injuries. The fact sheet also provides a list of agencies that farmers can contact for assistance when they experience secondary injuries. |

Machinery Safety on the Farm | Machines; no farm or ranch can function without them. They save valuable time and are essential to agricultural productivity. They also represent an ever-present danger to the people who operate them. There are a host of hazards that makes agricultural machinery the leading cause of injury and death on American farms and ranches. |

Determining Forage Moisture Concentration | Harvesting and storing forage at the proper moisture concentration is essential to producing a high-quality product. Ideally, hay forage should have a moisture concentration between 15 percent and 18 percent during baling. Hay baled at higher moisture levels is subject to heat damage, dry-matter loss, mold spoilage, and hay fires. Protein and total digestible nutrient losses are increased for hay baled at lower moisture levels. Baling at the proper moisture level is critical to making quality hay, especially for larger bales (round and square) since moisture and heat dissipate more slowly in comparison to smaller bales. |

Planning Fencing Systems For Controlled Grazing | Controlled grazing is an alternative method of providing forage to grazing animals. Using pasture as a major feed source during the grazing season can significantly reduce feed costs. Virginia’s soils and climate are especially favorable for the growth of a wide range of productive, high-quality grasses and legumes suitable for grazing. However, optimizing a controlled grazing system requires careful planning and good management of a fencing system. |

Selecting a Treatment Technology for Manure Management | Animal manure has been used for centuries as a fertilizer and a soil builder because it contains nutrients and organic matter. However, as animal production shifts toward fewer but larger operations, the number of confined animals has increased in some geographical locations, resulting in more manure produced than can be assimilated by the available farmland where the animals are raised. |

Selecting and Siting Poultry and Livestock Manure Storage Structures on Farms | Manure storage is a critical part of a nutrient management plan in a livestock or poultry operation. It's essential to recognize manure as a valuable resource, rich in organic matter and nutrients that can be used as fertilizer or for energy production. While manure can accumulate rapidly, effective management is key to reducing the potential for odors, surface water, and groundwater contamination. This responsible environmental practice not only mitigates these risks but also allows for a strategic approach to managing and using manure. It provides livestock and poultry operations with the flexibility to schedule its use, maximizing the benefits of the resources it contains. Our publication offers guidelines and information for choosing the type of storage and setting them up for farming operations, emphasizing the importance of this responsibility. |

Poultry and Livestock Manure Storage: Management and Safety | Storing manure is a common practice on farms and for those who keep animals. However, a well-designed manure storage facility must also be well-managed to prevent environmental concerns from developing. In most cases, manure storages are used when cold weather, wet conditions, and/or a lack of time do not allow field application. To get the most benefit out of the manure, good management practices and observation of safety practices that minimize manure hazards on the farm are crucial. This publication provides guidelines that stress the importance of good management and safety practices for manure storage to inform the safety and security of a farming operation. |

Manure Management and Environmental Stewardship | If not managed properly, manure can negatively impact the environment. Therefore, regardless of size, all livestock and poultry operations must handle manure effectively for economic benefits and environmental protection. Media reports often highlight community conflicts arising from livestock and poultry odors, fish kills, and the pollution of surface or groundwater due to poor manure management. These issues have strained relationships between the public and animal agriculture and can be minimized responsibly by managing manure and other agricultural wastes. Effective manure management begins with recognizing its value as a nutrient source for crops and understanding its potential negative effects on air, water, and soil. This publication provides general guidelines for managing livestock and poultry manure. It includes a list of resources with detailed information on best practices for manure management and uses that contribute to good environmental stewardship. |

Filtration, Treatment, and Maintenance Considerations for Micro-Irrigation Systems | Micro-irrigation systems can deliver water and nutrient in precise amounts and at controlled frequencies directly to the plant’s root zone. With micro-irrigation systems an extensive network of pipe is used to distribute water to emitters that discharge it in droplets, small steams, or through mini-sprayers. The major cause of failure in micro-irrigation systems is emitter plugging. Emitter plugging can severely degrade irrigation system performance and application uniformity. The goal of this document is to provide information on common water quality problems that can lead to emitter clogging, and how these problems can be addressed through water treatment and system maintenance. This should help producers identify, prevent, diagnose, and address clogging problems in their micro-irrigation systems. |

Mitigation of Greenhouse Gas Emissions in Agriculture | In this publication, information is presented on how to
increase farm productivity while potentially reducing
greenhouse gas* (GHG) contributions from agricultural
production. Some of the practices may be familiar
to many producers, such as building soil organic matter
(SOM) or increasing nitrogen fertilization efficiency,
but many producers may not know that these same productivity-boosting activities also help to reduce GHG
emissions and their impact on climate change. While
informative to the producer, this publication will also
inform those with an interest in both agriculture and
the environmental impact of GHG emissions on the
atmosphere. |

Greywater Reuse | Greywater is any household wastewater other than that used for toilet flushing.
This water could be reused around the home (for purposes other than drinking
water). An example of greywater use is landscape irrigation. Wastewater that
comes in contact with human waste is referred to as blackwater. However, the
definition of greywater varies according to state regulations. |

Using Reclaimed Water | Reclaimed water, sometimes referred to as “water reuse” or “recycled water,” is
water recovered from domestic, municipal, or industrial wastewater treatment
plants that has been treated to standards that allow it to be safely used for
designated purposes. Reclaimed water should not be confused with “wastewater,”
untreated liquid industrial waste or domestic sewage. However, “gray water,”
untreated water from bathing or washing, is considered one form of wastewater
(Water Reuse, VCE Publication 452-014).
The level of treatment and disinfection reclaimed water receives is dictated by its intended (and permitted) use. Many states encourage and promote the use of reclaimed water to conserve freshwater supplies and preserve rivers, streams, lakes, and aquifers.

Spray Water Quality and Pesticide Characteristics | Pesticide sprays consist of at least 95% water. Water quality plays an important role in pesticide performance. The following issues may indicate a compatibility problem with pesticides and spray water quality:
- Pesticide does not work at labeled rates;
- Difficulty mixing sprays or clogging of nozzles;
- Inconsistent pest control observed in fields or plots;
- Pests seem resistant to a new pesticide active ingredient, or
- Crops are lower quality or lower yielding.
Understanding how water quality characteristics such as pH, water hardness, turbidity, and total suspended solids affect the adsorption and persistence (half-life, storage time) of a pesticide can help pesticide applicators reduce or eliminate compatibility issues and improve pesticide effectiveness |

Understanding Spray Tank Mixing Practices | Mixing two or more pesticide products can allow for the treatment of several pests at the same time, improve pesticide performance, and ultimately saving time and money. However, physical and chemical tank mix incompatibilities can occur when combining two or more pesticides. Physical incompatibility is the failure of pesticide products to stay uniformly mixed and can result in layering, products settling out of solution, or clumping. A chemical incompatibility is the result of a chemical reaction between pesticide products. A chemical incompatibility is less visible and can be harder to detect. This publication focuses on basic factors that influence product compatibility (agitation speed and method, water temperature, mixing order, carrier type, and chemical formulations) and summarizes best mixing practices to address these factors. |
