Seeking Sustainability for Organic Cropping Systems in the Northern Great Plains: Legume Green Manure Management Strategies: Author: Izard, Erica Jean; Date: 2007-08-15; Program: Land Resources and Environmental Sciences; Abstract: Soil fertility in organic cropping systems of the northern Great Plains (NGP) is most often achieved through inclusion of leguminous green manures. The objectives in this study were to evaluate the efficacy of pea as green manure; and more specifically, measure the effects of pea green manure type, termination timing and method for soil water use and soil N contribution.
