1. Effect of Cover Crops and Compost on Soil Water Availability in Organic Dryland WheatIn low input semi-arid regions, water is the major limiting factor in crop production. Cover crop biomass and compost are good source of organic matter, that improve biological activity and water holding capacity of soils. However, dryland organic wheat growers rarely apply soil amendments due to cost and cover crops can lead to the depletion of soil water which decreases the yield of subsequent winter wheat. This study investigates the potential for a synergy between compost addition and cover... K. Adeleke, J. Reeve, E. Creech, I. Atoloye |
2. Tillage Effects on Phosphorus AvailabilityVertical stratification of phosphorus (P) has been documented in both no-till and reduced tillage systems, yet very few studies have determined if this stratification has affected P uptake, and none of these studies have been conducted in Montana. Stratification of P was compared in 1.2 in layers in a small plot study composed of four tillage systems: long-term conventional (sweep) till (CT), 10-yr no-till (NT), 1-yr NT and 1-yr CT. Olsen P was measured in the upper 12 in., and a sequential extraction... C. Jones, K. Neill, C. Chen, E. Allison |
3. Precision Fertilizer Management Enabled by Printed Sensors for Direct Soil Nitrate MonitoringModern farming relies on intensive fertilizer applications to ensure the plant production. However, a key challenge in fertilizer management, particularly nitrogen, is achieving a balance between maximizing crop yields and pursuing environmental stewardship. Uniform fertilizer applications often result in inefficiencies. Some areas receive insufficient fertilizer, resulting in reduced crop yields and caused financial losses. In contrast, other areas receive excessive amounts, leading to surplus... K. Chen, J. Andrews |
