Nitrogen Fertilization of Wheat No-Till Planted in Alfalfa Stubble
The N available after legumes is sufficient for maximum crop yields in many cropping systems. Fertilizing without accounting for the "extra" N mineralized from legume residues can contribute to high nitrate-N concentrations in the soil during crop production and increase nitrate-N leaching potential. Tillage practices also affect the physical, biological, and chemical nature of the soil, changi...
متن کاملNo-till Wheat Production in Oklahoma
Should I switch from conventional till to no-till wheat production? This is one of the most common questions asked by Oklahoma farmers, but it is also one of the most difficult to answer. There are several considerations when making this decision, and there is certainly no one-size-fits-all program for converting from conventional till to no-till wheat production. A few factors to be considered...

متن کاملNitrogen Fertility and Weed Management Critical for Continuous No-Till Wheat in the Pacific Northwest1
No-till cropping is an option for growers needing to reduce soil erosion in the Palouse annual-cropped region of the Pacific Northwest, which is well suited for wheat production. A 6-yr field study was conducted to determine optimum levels of fertilizer and herbicide inputs in a no-till continuous wheat crop production system. Three levels of nitrogen (N) and two weed management levels (WML) we...
متن کاملIn Situ Nitrogen Mineralization, Nitrification, and Ammonia Volatilization in Maize Field Fertilized with Urea in Huanghuaihai Region of Northern China
Nitrogen (N) fertilization potentially affects soil N mineralization and leaching, and can enhance NH3 volatilization, thus impacting crop production. A fertilizer experiment with five levels of N addition (0, 79, 147, 215 and 375 kg N ha(-1)) was performed in 2009 and 2010 in a maize field in Huanghuaihai region, China, where > 300 kg N ha(-1) has been routinely applied to soil during maize gr...
