This publication presents and discusses concepts that are fundamental to understanding soil, water, and plant relationships and the soil water balance. Knowledge about soil water relationships can inform the decision-making process in agricultural operations or natural resource management, such as determining what crops to plant, when to plant them, and when various management practices should be scheduled. Understanding these concepts is useful for addressing both agronomic and policy issues related to agricultural water management.

Virginia usually receives ample rainfall to support agriculture, but droughts in 2002, 2007, and 2010 led to severe problems for farms in many regions. Using groundwater for irrigation can help manage drought risks on farms without access to ponds or streams. However, installing groundwater wells can be expensive and time-consuming. The amount of water obtained from wells can vary in different regions of the state. This bulletin is intended to provide agricultural producers with information on technical and regulatory issues related to irrigating with groundwater.

This introductory information is primarily focused on solar-powered water pumping systems for tenant farmers and for systems designed for use only during freeze-free months. The information and the referenced demonstration systems are to help enhance pasture management options, while excluding livestock from surface streams, in situations where a permanent watering system may not currently be possible for the site. A permanent watering system is needed for ongoing year-round usage. Please refer to the resources listed in this publication for more general information and contact your local USDA Service Center to explore options for permanent livestock watering systems.

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

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.

Spray water problems may arise due to water quality and management decisions. Certain aspects of water quality can reduce the efficacy of the pesticide as well as affect how the pesticide interacts with the plant surface or targets pests. Evaluating and testing spray water chemistry can help identify water quality problems that might otherwise be overlooked. This publication will examine possible solutions to spray water problems, including the use of adjuvants and other additives to enhance pesticide performance.

The purpose of this systems research project led by National Center for Appropriate Technology (NCAT) was to identify and promote practical ways of using regenerative grazing practices to improve soil health and catch and hold more rainwater in soil. Virginia Tech and Virginia Cooperative Extension’s project team conducted eleven semi-structured interviews and conversations across Virginia to learn and better understand farmers’ and ranchers’ agroecological motivations and overall values related to the protection and conservation of water resources. The project aimed to highlight distinct and diverse farms of Virginia’s agricultural community through a narrative inquiry framework.

Bean Hollow Grassfed Farm is a multi-generation farm located in the shadow of the Blue Ridge Mountains in Rappahannock County. A core belief for Michael and Bean Hollow Grassfed Farm is having and encouraging a healthy ecosystem where farm and land management reinforce natural processes because a farm cannot be healthy if the land is sick. Sheep and cattle are their primary livestock, but they also have layers for eggs. Most of their meat sales are sold through their on-farm store. In this video, Michael shares about his early career as a researcher and educator with the Rodale Institute but also tells how the gnawing in his gut led him into farming and the move toward more regenerative practices that strengthen biodiversity, build soil health, sequester carbon, and his family’s efforts to mitigate climate change. Farming for Mike is about continuous improvement; assessment of finances and hard to measure ecological metrics; and making management decisions that push forward the adoption of regenerative practices, while being mindful of farm transition and conservation planning.

Bramble Hollow Farm is owned and operated by Brent and Anna Wills and is located along the eastern foothills of the Blue Ridge Mountains in Bedford County. Brent and Anna and their family raise pork and chicken on pasture. They have also raised other livestock and poultry through the years. Brett and Anna have and continue to use multiple market channels including farmers markets, on-farm sales, community supported agriculture (CSA) deliveries, participation in a food hub, and affiliation with the Edible Goose Creek farm alliance. Additionally, Bramble Hollow Farm invested in an on-farm commercial kitchen to diversify and add value to what they grow and offer. In this video, Brent shares who (i.e., writings of Gene Logsdon, Wendell Berry, and others) and what influenced him and helped form his vision for regenerative agriculture where soil health equates to plant health; plant health equates to livestock health; and ultimately equates to human and planetary health.

Cattle Run Farm LLC is a third-generation family operated and veteran owned farm located in Greene County and the central Piedmont region of Virginia. Sarah Morton and Ralph Morton seek to carry on the tradition of their family and expand the concept of an agrarian lifestyle and business to the community. Sarah shares about her families’ roots in farming and how asset mapping played a critical role when her father wanted to transition to the next generation. Sarah and Ralph raise cattle, chickens, produce, blackberries, hogs, cows, and more as they continue to look to add value and diversify their operation. Sarah and Ralph are active members in the Minority and Veteran Farmers of the Piedmont and work closely with several other community-focused organizations. Sarah emphasizes that Cattle Run Farm’s story is one of resilience, scale, diversification, and fortitude to keep farming and reaching towards sustainability and empowering others. Like many multi-generational family farms, sustainability, resilience, and viability are forged out of necessity. Sarah reiterates the critical importance of community in farm viability and similarly how farm viability strengthens community viability beyond the farm’s gate. Overall, the story gives a glimpse into Sarah’s and Ralph’s ecological and social consciences, and how reconnecting to the land instills passion and power.

Gil Yearwood of Ellett Valley Beef Company reflects on his time raising beef since 1975. Ellett Valley Beef Company is in Montgomery County in southwest Virginia and specializes in South Poll cattle because they are excellent for grass-based grazing systems and have relatively small frames, easy dispositions, and are tender. Gil admits he has tried every variation of rotational grazing, and that rotational grazing is significantly better than continuous grazing. Gil took an interest in cattle and grazing as a teenager. He has been a mentor for many young and second career cattle farmers. Gil demonstrates that regenerative agriculture and grazing is a journey and an adaptive lifelong process. Gil openly shares his overarching goals, challenges, the lessons he has learned, and what gives him hope with soil health, water quality, and regenerative grazing adoption as he interacts with other farmers and visitors to his farm.

Becky Szarzynski is the owner and operator of Ember Cattle Company in Fairfield in Rockbridge County, Virginia. Becky as a grazier has honed her grazing management skills over the past 15 years in working with her father, attending conferences, being mentored by other farmers, and serving in a coordinator role of the farmer-to-farmer mentoring network with the Virginia Forage and Grassland Council. Becky raises South Poll cattle as a cow-calf operation, breeds replacement heifers, and sells seed stock on 160-acres of land. Becky practices rotational grazing with a diverse forage base that includes native warm season grasses, summer annuals, and cool season perennials. Becky tends to prefer the term adaptive grazing versus rotational grazing because conditions are constantly changing and you must be very observant of the interactions between soil health, plant diversity, livestock, pollinators, the weather, stocking density, and overall system. Becky shares her motivations, lessons learned, aspirations, and ongoing research and study of grazing and of course her fascination with dung beetles.

Glade Road Growing is a small family farm within the town limits of Blacksburg in Montgomery County, Virginia. Sally Walker and Jason (JP) Pall started the farm operation in 2010, building on their experience with home gardening. Sally and Jason did not grow up on farms but have learned through internships, conferences, reading, YouTube videos, farm visits, and their own experiences as the farm has grown the past 14 years. Sally and Jason and their growing full-time and part-time staff raise certified naturally grown produce and pasture-raised organic-fed pork, poultry, and eggs. Sally and Jason have worked with the USDA-Natural Resource Conservation Services on several cost-shared soil and water conservation practices. Glade Road Growing started marketing their produce at the Blacksburg Farmers Market, but their sales now include a farm stand and a season-long farm share and community supported agriculture (CSA) subscriptions. Nutrition, health, and connections with community are critically important to Glade Road Growing’s mission and vision. Although JP and Sally are not quick to use the term regenerative for their vegetable production practices and livestock rotations, respect for their soil, water, animals, staff, and customers is always at the forefront of their thinking and that they are growing together with the community in mind.

Heaven’s Hollow Farm is a fourth-generation family farm that has been in operation since 1951. Jacob and his wife Jennifer and children operate the farm in Orange, Virginia. Jacob is a first-generation farmer. Jacob is thankful for the support of his parents and credits his involvement in 4-H showing cattle as a teenager for his career in farming and conservation. Jacob continues to learn and study through reading and visiting with other farmers. Heaven’s Hollow Farm is a commercial Black Angus cow-calf operation that also includes pastured poultry and pork. Most of their beef, poultry, pork, and eggs are marketed directly to consumers and local restaurants. Jacob and Jennifer take a holistic approach to managing their farm and seek to improve soil health, water quality, bird and wildlife habitat, and pollinator diversity as much as possible. Jacob describes their thinking about these processes and their rotations. Soil health, profitability, and quality of life must be balanced and should not be too complex. Being flexible and adaptable is important for Jacob and Jennifer, particularly with grazing, raising a family, and managing the farm holistically.

Holsinger Homeplace Farms is a family farm in Rockingham County in the central Shenandoah Valley. Buck and Amand ‘AJ’ Holsinger and their children are the tenth and eleventh generations to live on the farm. Buck and AJ started farming with the goal of feeding their family the healthiest food possible. Their animals are raised humanely and given the freedom to roam and obtain a nutritious diet from the forage base and their silvopasture system that includes black locust, black walnut, pine, cedar, and other mast, fodder, and shade producing trees. Holsinger Homeplace Farms now provides other families excellent grassfed beef and eggs from free-range laying hens. Buck and AJ share their motivations and how they have a generational perspective. J. Russell Smith’s book Tree Crops was an early influence and motivation for Buck, along with his experience visiting other countries as a veteran and pilot. AJ’s background in dietetics and nutrition has influenced her perspective on soil, plant, and animal health. Silvopasture management is a centerpiece of their farm as they seek a system that is multi-functional and provides multiple benefits across time. USDA and state conservation and cost-share programs have helped them financially in getting started and allowing them to set a pathway for transforming the farm and achieving their long-term holistic vision.

Shamoka Run Farm is a modest family farm in northern August County operated by Leo and Judy Tammi. Leo grew up in Delaware on a small, diversified farm with a few milk cows, hogs, sheep, and poultry. Leo and Judy moved to the Shenandoah Valley region in 1981. Leo learned very early to farm with nature and what the land is best suited. Shamoka Run Farm is a sheep and lamb farm that includes about 240 acres of hay and pasture, along with 60 additional acres of rented land. Leo was a founder of the early Virginia Lamb Cooperative, is an active member of the Virginia Forage and Grassland Council and has worked with the USDA-Natural Resources Conservation Services and Headwaters Soil and Water Conservation District on a variety of best management practices like riparian buffers, bird and pollinator habitat, and native grass plantings. Leo shares several epiphanies and observations on rotational grazing, resilient, aesthetics, marketing, and wildlife habitat, and the need to educate people about the complexity of farming and the services farming and good land productivity provides to the broader community. Leo reminds us that regenerative and soil health-building principles must be internalized, require inquisitiveness, energy, resilience, and continual observation.

Adam Taylor and Elizabeth Spellman-Taylor co-operate Singing Spring Farm, which is in the Sinking Creek Valley in Craig County, Virginia. Adam and Elizabeth’s goal is to be a whole, complete diet farm that offers heirloom fruits and vegetables; goat milk, kefir, and cheese; culinary and medicinal herbs; eggs; and pastured, lamb, goat, and poultry. Agroforestry and permaculture are important themes on their farm as they seek to protect the Singing Spring on their farm, create community, and live out paradise gardening. Adam’s experience interning on a farm in southwest Virginia and being a Peace Corps volunteer in Zambia profoundly impacted how he views farming, while Elizabeth has a deep conservation ethic in agricultural land protection and agrarian commons. For each of them, Joe Hollis’s essays and musings on Paradise Gardening were instrumental for their vision of a family lifestyle that was balanced with everyday practices.

Jerry Swisher is a cattleman, farm consultant, and a retired Senior Extension Agent for dairy sciences. Jerry continues to own and operate his family’s farm in Fairfield and Brownsburg in Rockbridge County, Virginia. Throughout his career with Virginia Tech and Virginia Cooperative Extension, Jerry served in many capacities to support Virginia’s dairy farmers, 4-H youth, and industry. Jerry designed and developed the Dairy Rotational Loafing Lot System, which became a standard best management practice for dairy farms to prevent soil erosion, protect natural resources, and enhance cow comfort and performance. Jerry was instrumental and a key resource for Virginia and Mid-Atlantic dairy farmers who desired to transition to grass-based dairy systems. He led multiple educational tours regionally and internationally so farmers could learn from other grass-based farmers in Ireland, New Zealand, and Australia. Jerry provides an historical perspective and motivated farmers to transition to grazing systems rather than conventional confinement with limited access to pastures. Jerry documents farmers’ motivations for grazing in an era of high costs and frantic industrial change, the pushback from the dairy industry, and frequently asked questions about grass-based regenerative dairy farming.
