|Land Application of Broiler and Turkey Litter for Farming Operations Without a DEQ Permit||
Poultry litter (poultry manure and a bedding material such as sawdust, pine bark, or peanut hulls) is a good source of nutrients and organic matter for growing crops. Land application of poultry litter on farms has been the mainstay of effective and safe usage for years. Unfortunately, improper management of litter applications may cause nutrient enrichment and/or contamination of surface and ground water resources. The key to proper management is an understanding of the nutrients available in the litter, the nutrient requirements of the crops to be produced, and the potential for the litter and/or nutrients to reach surface or ground waters.

|Manure Spreader Calibration for Rear-discharge Equipment -- Handling Solid and Semi-solid Manures and Poultry Litter||
To maximize crop productivity and minimize adverse environmental effects, it is critical that land applications of manures meet, but not exceed, crop nutrient requirements. To assure that the actual manure application rate matches the desired application rate, manure-spreading equipment must be calibrated. The goal of manure spreader calibration is to determine the amount of manure, on a weight per unit area basis, that is being applied to a field. This publication describes three methods for manure spreader calibration for spreaders handling solid and semi-solid manures.

|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.
