When growing vegetables and specialty crops, a soil high in organic matter is very desirable. When examining soils in Virginia, we struggle to find soils that are naturally high in organic matter.

|Impact of Changing From Nitrogen- to Phosphorus-Based Manure Nutrient Management Plans||
Animal manures are a good source of nitrogen (N) and phosphorus (P) for agricultural crops, but they have an imbalance in their N to P ratio, so that if they are applied to meet crop N needs, then P is overapplied. For many years, manures have been applied to meet crop N needs, which has resulted in some soils containing more P than crops require, leading to environmental concerns. Regulations have been developed to limit P losses from manures and soils high in P by moving manure nutrient management from an N basis to a P basis.

|Importance of Farm Phosphorus Mass Balance and Management Options||
Phosphorus is a naturally occurring element that is one of 16 elements essential for plant growth and animal health. Research has documented that applying phosphorus in fertilizers or manure increases crop growth and yield on soils that are below critical agronomic levels, as measured during routine soil testing. Although the economic benefits of phosphorus fertilization on crop production are well-documented, too much of a good thing can be detrimental to the environment. Excessive soil phosphorus is a potential threat to water quality.

|Nitrogen Soil Testing For Corn in Virginia||
An adequate supply of plant-available nitrogen (N) is crucial for efficient corn production, and corn N requirements are greater than any other nutrient. For example, a corn crop yielding 150 bushels per acre typically contains about 165 lbs N in the grain and stover, or approximately 1.1 lbs N/bu grain. These calculations are based on actual N uptake, and allowances must be made for actual fertilizer use efficiency and soil N availability.

|Phosphorus, Agriculture & The Environment||
Phosphorus (P) is a naturally occurring element that can be found in the earth's crust, water, and all living organisms. Phosphorus (P) is one of 16 elements that are essential for plant growth. Soils in Virginia are naturally low in phosphorus, and most cropping systems on these soils require supplemental phosphorus to maximize their yield potential.

|Powell River Project - How to Restore Forests on Surface-mined Land||
Most coal-bearing lands in the Appalachian region were forested prior to mining. The region’s forests are predominantly upland oak-hickory and Appalachian mixed hardwoods. These forests provide many benefits to landowners and the public. Solid wood and paper products are perhaps the most tangible benefits, but a predictable flow of high-quality water from forested watersheds into regional streams is another vital benefit provided by the region’s forests. Forests also fix carbon from the atmosphere, provide wildlife food and cover, and provide recreational opportunities and an aesthetically pleasing environment.

|Precision Farming Tools: Soil Electrical Conductivity||
Soil electrical conductivity (EC) is a measurement that correlates with soil properties that affect crop productivity, including soil texture, cation exchange capacity (CEC), drainage conditions, organic matter level, salinity, and subsoil characteristics. This publication discusses: 1) How, with field verification, soil EC can be related to specific soil properties that affect crop yield, such as topsoil depth, pH, salt concentrations, and available water-holding capacity; 2) Soil EC maps often visually correspond to patterns on yield maps and can help explain yield variation; and 3) Other uses of soil EC maps (Table 1), including developing management zones, guiding directed soil sampling, assigning variable rates of crop inputs, fine tuning NRCS soil maps, improving the placement and interpretation of on-farm tests, salinity diagnosis, and planning drainage remediation.

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.
