1. Changes in Soil Quality During the Transition from Irrigated to Dryland Cropping SystemsThe availability of irrigation water enhances crop productivity and, in turn, increases crop residue inputs and soil quality. With increased pressure on declining groundwater resources, some formerly irrigated lands are being transitioned to dryland management. However, little is known about the shifts in soil quality after conversion from irrigated to dryland cropping systems. The objective of this work was to quantify the effect of irrigation retirement on the early changes in soil quality.... A. Nunez, R. Ball, M. Schipanski |
2. 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.

3. Soil Properties Affected by Grazing and Tillage of Annual ForagesNo-till (NT) management of annual crop production systems increases precipitation capture and storage. However, compaction with annual livestock grazing and the development of herbicide resistant weeds present challenges to long-term NT. An on-farm study was established in 2016 near Jetmore, KS to investigate the influence of annual tillage with a sweep plow compared to NT in a grazed continuous winter triticale production system. Forage productivity as well as weed density and soil properties... P. Mauler, J. Holman , A. Obour , L. Simon, K. Roozeboom |
4. Impact of Nitrogen Fertilizer Source and Application Date on the Yield and the Quality of Winter WheatNitrogen (N) is one of the most important and critical nutrient elements in agricultural systems, and its effect directly affects crop productivity and nutrient content. Our field studies were related to the wheat Crop. They were conducted in four locations to evaluate the effect of various Nitrogen sources (SuperU, Urea, UAN and UAN+Anvol) applied at three different times (pre, greenup and jointing). The experimental design of the four locations was randomized complete with... H. Moulay, B. Arnall |
5. Comparative Analysis of Different On-the-Go Soil Sensor SystemsThis study is part of the field of precision agriculture. This management mode is one of the great revolutions in the agriculture field, and it means better management of farm inputs such as fertilizers, herbicides, and seeds by applying the right amount at the right place and at the right time. Precision agriculture aims to divide the farm into management plots where each receives customized management input based on soil fertility status, landscape position, and management. also provides...
