... when evaluating soil erosion. Plant nutrients are transported in windblown sediment. The Wind Erosion Equation (WEQ) is designed to predict long-term average annual soil losses from a field having specific characteristics. The equation is E=f (IKCLV), where E is the estimated average annual soil loss, I is the soil erodibility, K is the ridge roughness factor, C is the climatic factor, L is the ... and environmental alternative to conventional farming is organic crop production. Organic farming is a soil management system that maintains and replenishes soil fertility. Organic foods are ...
