The effects of cropland slope, distance to surface water, farmers' risk attitudes, and farmers' nitrogen (N) fertilizer applications on potential N delivery to streams and costs of reducing N delivery were evaluated for a representative Virginia peanut-cotton farm. Target MOTAD and generalized...

On a Virginia crop farm, alternative levels of information are evaluated for managing nitrogen applications based on soil properties and yield potential. Application of variable rates of nitrogen based on crop yield potential can increase profitability and reduce nitrogen pollution potential.
