1. Assessment of Long-term Effects of Tillage and Nitrogen Management Practices on Irrigated Corn Yields and Nitrogen Use EfficienciesCorn grain yields and crop nitrogen uptake are affected by management factors such as tillage intensity and nitrogen rates. Additional data about the long-term effects of tillage and nitrogen rates on yields and nitrogen use efficiencies of irrigated corn are needed. We are presenting preliminary results from a 17-year study about the effects of these management practices on irrigated corn yields and nitrogen uptake in a Fort Collins clay loam soil at Colorado State University’s Agricultural...

2. Stacking Regenerative Agricultural Practices Under Irrigated Forage ProductionIncorporation of forage production into producer landscapes is an opportunity to hedge economic risk and increase yield stability. Regenerative agricultural management practices that also reduce N fertilizer and pest control costs, recycle nutrients, and preserve and capture precipitation are needed in semi-arid regions. There is little information on how the combination of regenerative practices such as no-tillage (NT) and cover crops will influence the timing and effect (e.g., additive,... C.E. Stewart, D.K.
