1. Effects of Residue Placement on Co2 Loss in an Irrigated, No-till Corn System It is well known that residue management practices that leave crop residue on the surface, such as no-till agriculture, promote soil fertility. However, the effects of such practices on carbon sequestration can be highly variable. To better understand how residue management impacts the loss of carbon through mineralization, we investigated the effects of residue location and addition on CO2 produced from residue decomposition under no-till irrigated continuous corn in Northern Colorado. Over... H. Oleszak, F. Cotrufo, S. Leichty, C. Stewart Download paper
2. Enhanced Efficiency Phosphorus Fertilizers Phosphorus (P) is essential for plants. However, first-year phosphorus fertilizer uptake by plants is low, resulting in economic and environmental impacts. Developments with P Enhanced Efficiency Fertilizer (EEF) sources show improved uptake efficiency and increased yield and/or crop quality, while reducing environmental risk. Research with EEFs (including organic acids, maleic itaconic copolymer, and struvite) all show these improvements, especially when: 1) soil test P concentrations are low,... S. Kobza, B.G.
