For the past two years, Arable has had the opportunity to spend a considerable amount of time learning from Frank Muller, his son Colin, and the other irrigation specialists on their staff about how to design and implement a specialized irrigation strategy that could shape the way crops are grown and watered. From February through August each year, we have the ...

The next revolution in agriculture will be defined by our ability to optimize data-driven crop productivity. We are now at the beginning of the next revolution in agriculture. It is a race to connect farm fields around the world with useful, valuable data, and will be defined by our ability to optimize data-driven crop productivity, from the smallholder to the ...

This study was carried out to evaluate the use of the crop water stress index (CWSI) for irrigation scheduling of sugar beet for two years under the semi arid climate of Iran. ...
Different zones within the circle may have unique thresholds based on soil type, drainage characteristics and other factors, and will get different amounts of water. “At midnight, it takes this data … and spatially calculates the crop water stress for each management zone,” O’Shaughnessy says. ...

They used 16 prototype wireless sensors on a center-pivot irrigation system to monitor crop canopy temperatures. They chose sorghum because of its importance as a cash crop in the Southern High Plains and because it withstands water stress. ...
Besides the improvement of irrigation techniques a task of primary importance is solving the problem of intra-seasonal irrigation scheduling under limited seasonal water supply. An efficient scheduling algorithm has to take into account the crops' response to water stress at different stages throughout the growing season. ...
Two common methods include tracking crop evapotranspiration (ETc) and tracking the water content with a sensor buried in the soil. In Colorado, a popular online tool that estimates the ETc for a variety of well-irrigated crops is the Colorado Agricultural Meteorological Network (CoAgMet). However, the use of CoAgMet to estimate the ETc of a ...
The modeling of yield response to water is expected to play an increasingly important role in the optimization of crop water productivity (WP) in agriculture. During 3 yr (2004–2007), field experiments were conducted to assess the crop response to water stress of quinoa (Chenopodium quinoa ...
