This webinar will describe opportunities to integrate crop and livestock systems and how soil health responds to grazing of cover crops and perennial forages in diverse agricultural operations.
Integrated crop-livestock systems are complex in form and in function – not only above-ground, but also below-ground. The input of carbon in integrated crop-livestock systems is often greater than in traditional cropping systems, the result of which leads to changes in soil microbial communities and nutrient dynamics. Rotation of cash crops with grazed cover crops and grazed perennial pastures can contribute to surface soil organic carbon and nitrogen accumulation. Active root growth for a longer period of time throughout the year results in greater rhizosphere activity and subsequent carbon mineralization and nutrient cycling. Unique soil carbon and nitrogen dynamics in integrated crop-livestock systems will be explored in this presentation, as well as description of a simple biologically based measurement to assess nutrient cycling.
This webinar is presented by the USDA NRCS Soil Health Division.
