Effects of Reduced Tillage and Split Fertilizer Application in Organic Broccoli and Pepper Production Systems
Is Version Of
The use of tillage is widespread in organic vegetable production, due to its importance for cover crop incorporation, seedbed preparation, and weed control. However, its harmful effects on soil health have spurred interest in systems that reduce the need for tillage. Because nitrogen is often limiting under high residue/reduced tillage conditions, fertilizer management is considered key to crop productivity. This two-year study is being conducted to evaluate the effects of cover crop-based no tillage and strip tillage systems, as well as split fertilizer application, on yields and nitrate leaching in organic broccoli and pepper production systems.
