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. Precision Mapping Technology in Dryland Cropping SystemIncreasing availability of cropland geospatial data are providing farmers with opportunities but also challenges in interpreting these data for precision cropland management decisions. The objective of this study is to evaluate spatial variability and precision management decisions using mapping technology in dryland cropping system. The study was initiated in 2018 in Akron, Colorado on field size plots ranged from 2.4 to 4.5 ha (6-11 acres) with substantial production variability. ... M.M. Mikha, D.M. Barnard, K.R. Mankin |
