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 |
3. Influence of Irrigation Timing and Amount on Cotton Physiology and Nutrient PartitioningThis study explores the impact of varying water levels on nutrient uptake in cotton plants, known for its sensitivity to environmental conditions. Recognizing the pivotal role of water availability in agricultural productivity, the experiment employed different irrigation scenarios and assessed the efficiency of nutrient absorption in cotton under these varied circumstances. The research also focused on analyzing nutrient content in different plant tissues,... K. Vargas, K. Lewis, J. Bicaldo, J. Burke |
4. Evaluation of the Nutrient Requirements and Uptake Indices of Ten Modern Cotton CultivarsThis study aims to re-evaluate the partitioning patterns and nutrient uptake index of new and soon-to-be released cotton cultivars to optimize the nutrient inputs for farmers and producers. The study will be divided into two phases: Phase I will be the determination of different nutrient uptake indices of 10 modern cotton cultivars and Phase II will be the development and establishment of new fertilizer management strategies for modern cotton cultivars using the results of plant nutrient uptake...
