Virginia No-Till Fact Sheet Series Number Five - Understanding Ammonia Volatilization from Fertilizers | Loss of nitrogen (N) as ammonia gas (NH3) is known as volatilization. While
volatilization directly from soil can occur, such loss is generally relatively small
compared to the amount that can be lost from fertilizers. Volatilization losses can be
significant with granular urea and urea-ammonium nitrate (UAN) sources, but the amount
of loss varies greatly depending on placement of the fertilizer, soil pH, soil texture,
and climatic conditions after application. |

Soil Test Note #2 - Field Crops | Most Virginia soils are acidic and require lime applications at three- to five-year intervals. Maintaining the correct soil pH has several benefits, such as encouraging healthy root development and making sure nutrients in the soil are available to the plant. For example, low pH can cause aluminum toxicity and can decrease phosphorus availability. |

Virginia Cover Crops Fact Sheet Series No. 1: Beneficial Uses of Cover Crops | The general purpose of a cover crop is to improve the soil, the broader
environment, or other crops in rotation, not for direct harvest. Cover
crops, depending on which are selected, are capable of providing many
diverse assets. This publication provides a short description of these
main benefits. |

Virginia Cover Crops Fact Sheet Series No. 2: Cover Crop Performance Evaluation in Field and Controlled Studies | Cover crops increase soil organic matter, reduce erosion, suppress weeds,
forage for nutrients, and reduce fertilizer costs (Clark, 2007). Cover
crop species vary greatly and provide varied benefits. Performance
evaluation of cover crop species and mixtures is needed in Virginia. |

Nitrogen and Sulfur Leaching Potential in Virginia | Early summer often means locally heavy and sporadic rainfall as thunderstorms deliver intense rains, and 2015 appears to be no different with many areas in eastern Virginia receiving 3+ inches of rain in a few days (Figure 1). These storms also often coincide with the timing of sidedress nitrogen (N) and sulfur (S) applications on corn. While some rainfall after sidedress is very beneficial to facilitate N movement into soil, heavy rain (2+ inches) often leaves us wondering how much, if any, of that recently-applied N remains and if additional N is needed. |

The Nutrient Value of Straw | The mature and dried stem, leaves, and chaff remaining after barley and wheat are harvested is known as straw. Many farmers around Virginia harvest straw by baling in small bales, large round bales, or large square bales that range in weight from 40 to 1,000 lbs. plus per bale. |

Virginia Tech Corn Silage Testing 2015 | This report contains the results for performance trials from commercial corn
hybrids produced for silage at four locations in Virginia in 2015 as well as
two and three year average performance, when available. In order to avoid
problems with comparisons over sites and years, multi-year yields are
presented as a percentage of the total called relative yield at that
particular site-year combination. All locations were planted with a
Wintersteiger PlotKing 2600 planter and harvested with commercial silage
equipment. Yields are presented on a dry matter and 35% dry matter basis for
comparison. Quality analysis was performed using a Foss NIR XDS Rapid
Content Analyzer. All hybrids entered in the Virginia trials were submitted
for testing by commercial companies. The locations at which particular
hybrids were entered were specified by the company. Companies entering
hybrids were charged a fee for each hybrid per location to support the
Virginia Corn Silage Performance Trials. |

Virginia Corn Hybrid and Management Trials in 2015 | Performance trials of commercial corn hybrids were conducted at six locations
in Virginia in 2015. The Mt. Holly location consisted of both an irrigated
and non-irrigated test. All locations were planted with a Wintersteiger
PlotKing 2600. All locations were harvested with a Massey-Ferguson 8XP plot
combine. Yields have been adjusted to 15.5% moisture. Grain test weight,
moisture, and plot grain weights were measured with a GrainGauge®
manufactured by HarvestMaster. A list of the companies participating in the
trials is shown in the above table. All hybrids entered in the Virginia
trials were those submitted by commercial companies. The locations at which
particular hybrids were entered were specified by the company. Companies
entering hybrids were charged a fee for each hybrid per location to support
the Virginia Corn Hybrid and Management Trials. |

Yellow Corn in Virginia – Spring 2016 | Many of the corn fields on the Eastern Shore and in Eastern Virginia are “yellow” and stunted due to the weather this Spring (Figs. 1 and 2) and is similar to conditions that Virginia farmers experienced in Spring 2010. There are many reasons for the corn to be yellow that range from nutrient deficiencies to abiotic factors. |

Value and implications of corn stover removal from Virginia fields | There has recently been increased interest in the use of crop residues for different industrial uses in the US and the world. Corn residue is frequently cited as the most likely candidate for alternate industrial uses because of the large area of production and the relatively large amount of residue produced per acre. Among the potential alternate uses for corn stover, biofuel production has received the greatest attention. |

Yellow Corn in Virginia – Spring 2017 | According to Meteorologist Scott Minnick with the NOAA-National Weather Service in Wakefield, VA, May 2017 is “yet another wet and cloudy May for the record books. With the rain on [May 31, 2017], Norfolk moved up to the 3rd wettest May on record.” The 2017 growing year is almost identical to last year (the wettest May on record for Norfolk, VA), with a dry March and April leading into a record breaking cool and wet May as corn tries to establish roots. Young corn largely depends on residual and starter fertilizer prior to sidedress applications and these fractions can be impacted greatly with excessive rain. |

Sensor-Based, Variable-Rate Nitrogen Applications in Virginia | Variable-rate applications (VRA) of nitrogen (N) fertilizers
are a new option to assist producers with real-time
fertilizer rate decisions. Two commercially available
systems that allow variable-rate nitrogen applications
are GreenSeeker (Trimble Navigation Limited; www.
ntechindustries.com/greenseeker-home.html) and the
OptRx Crop Sensor (Ag Leader Technology; www.
agleader.com/products/directcommand/optrx/). A discussion
of the science behind these systems, potential
economic benefits, and other methodologies to make
VRA is discussed in Virginia Cooperative Extension
publication 442-505, “Precision Farming Tools: Variable-
Rate Application” (Grisso et al. 2011). |

2015 Virginia Grain Sorghum Performance Tests | The 2015 grain sorghum OVT tests contained 21 hybrids planted as a full season crop and 22 as double crop. Full season tests were conducted at three
locations, the Tidewater Agricultural Research and Extension Center (TAREC) in
Suffolk, VA, the Eastern Virginia Agricultural Research and Extension Center
(EVAREC) in Warsaw, VA, and in a farmer field near Windsor, VA, in Isle of
Wight County. The double crop sorghum trials were conducted at three locations, the TAREC, in a farmer field near Windsor, VA, in Isle of Wight County, and in a farmer field near Locust Grove, VA, in Orange County. |
