1. Nitrogen Fertilizer Application and Depth of Moist Soil at Planting Affected Grain Sorghum YieldThe depth of moist soil before planting is critical for grain crop production in intensified dryland cropping systems. We investigated depth of moist soil at planting and nitrogen (N) fertilizer application rate effects on continuous grain sorghum yields on a Crete silt loam soil over 32-years in western Kansas. Treatments were four N rates (0, 20, 40 and 60 lb ac-1) in a randomized complete blocks design with four replication and depth of moist soil at planting determined with Paul... A.K. Obour, J.D.

2. Soil Properties and Winter Wheat Nutrient Uptake As Affected by Long-term Tillage and Nitrogen FertilizationKnowledge gained on the long-term effects of crop management practices on soil fertility is critical in developing nutrient management strategies to optimize crop yields and environmental sustainability in semi-arid cropping systems. This study examined the long-term effects of nitrogen (N) fertilizer management and tillage intensity [conventional tillage (CT), and no-tillage (NT)] on soil properties and nutrient uptake in a dryland wheat-sorghum-fallow cropping system. Results showed winter wheat... A. Obour, J. Holman, L. Simon, Y.M. Assefa |
