175 Integrating Livestock Into Cropping Systems: Ecosystem Responses From Long-Term Studies

Oral Session
Special Sessions Managing agricultural production systems for enhanced ecosystem services such as the sequestration of carbon (C) to offset increasing greenhouse gas (GHG) emissions and enhanced biodiversity and water conservation is a critical focus of agriculture in the US and worldwide. Integrated crop-livestock systems in semi-arid and humid climates have shown promise for conservation of water, nutrients, soil organic C and increased microbial communities. This symposium is a summary of the long-term research conducted in integrated crop-forage-livestock agroecosystems and their impacts on soil-plant-animal interactions and the economic costs and benefits.
