                        Project Type: Non-Assistance Cooperative Agreement Start Date: Sep 22, 2023
                        
                        End Date: Sep 21, 2025 **Objective:**
                        
                        Determine how ground pressure from various tire and vehicle configurations during harvest impacts soil characteristics and crop yields of alfalfa intercropped with corn. **Approach:**
                        
                        Small plot studies indicate alfalfa-corn intercropping can enhance soil and nutrient conservation and improve forage production but the impact of full-sized harvest equipment on this production system is not known. A replicated field experiment will be initiated in May 2024 at the Cooperator's farm to examine five levels of wheel traffic intensity imposed on the intercropping system. The study will include a conventionally established and harvested stand of spring solo-seeded alfalfa as a control treatment. Measurements will include corn silage yield and post-harvest assessments of soil compaction and alfalfa stand density, health, and forage yield.
