Efficient use of freshwater resources is necessary to balance food production and long-term sustainability of irrigated agricultural systems. Here we developed a framework to benchmark irrigation water use relative to crop yield for individual fields based on site-specific weather and soil. Subse... Read More
There is an increasing need to strategize and plan irrigation systems under varied climatic condi-tions to support efficient irrigation practices while maintaining and improving the sustainability of groundwatersystems. This study was undertaken to simulate the growth and production of soybean [G... Read More
Agricultural water management (AWM) is an interdisciplinary concern, cutting across traditional domains such as agronomy, climatology, geology, economics, and sociology. Each of these disciplines has developed numerous process‐based and empirical models for AWM. However, models that simulate al... Read More
We use an 82-year record of water table data from the High Plains Aquifer to introduce a new application of segmented regression to hydrogeology, and evaluate the effects of droughts, crop prices, and local groundwater management on groundwater level trajectories. Across the High Plains, we find ... Read More
Crop water productivity and return after variable cost for three major crops (winter wheat, grain sorghum and maize) in the southwest Kansas were evaluated based on simulated yield using the Decision Support System for Agrotechnology Transfer - Cropping System Model (DSSAT-CSM). Winter wheat and ... Read More
The future of the South Asia’s rice-wheat (RW) production system is at stake due to continuously depleting aquifers and increasing pressure on underground water under projected climate change scenario. Conventional management factors such as flood irrigation, intensive tillage and residue burni... Read More
Irrigated agriculture is a major economic contributor of the High Plains Region and it primarily relies on the High Plains Aquifer as a source of water. Over time, areas of the High Plains Aquifer have experienced drawdowns limiting its ability to supply sufficient water to sustain fully irrigate... Read More
An efficient management of our precious water resources is not possible without acquiring a comprehensive and detailed understanding on water fluxes at irrigated areas. In the past few decades, agricultural water balance analyses have been carried out at a wide variety of temporal (from hourly to... Read More
With an increasing demand of fresh water resources in arid/semi-arid parts of the world, researchers and practitioners are relying more than ever on remote sensing techniques for monitoring and evaluating crop water status and for estimating crop water use or crop actual evapotranspiration (ETa)....

Optical and thermal remote sensing data were acquired at ground level over several turfgrass species under different soil and irrigation treatments in northern Colorado, USA. Three vegetation indices (VIs), estimated based on surface spectral reflectance, were sensitive to the effect of reduced w... Read More
