Erosion took a serious toll of prime topsoil from wheat fields in the Pacific Northwest United States since farming began in the 1870s. By the mid-1900s, it had become a serious environmental and economic threat to the region that produces world-reco

Different chemical, physical, and biological properties of a soil interact in complex ways that determine its potential fitness or capacity to produce healthy and nutritious crops. The integration of these properties andine resulting level of product

The addition of N fertilizer to soil has been shown to stimulate the uptake of native soil N via a priming effect recently termed added nitrogen interaction (ANI). This ANI, due to pool substitution, can substantially affect the N-recovery efficiency

Predicting the rate and extent of decomposition of residues at the soil surface is necessary to evaluate the impacts of minimum-tillage practices on erosion control and thus ensure the most effective use of residues. A mechanistic model simulating th
