To determine if there are agronomic and/or economic benefits of intercropping or living mulch crops to the subsequent crop in the following growing season. This includes examining weed pressure, N benefit from legumes, disease pressure, and grain yields and quality. In addition, 1) growth and nutrient uptake models will be developed to determine optimum intercrop ratios and 2) intra-specific competition for nutrients and soil moisture will be quantified for different seeding ratios.
