One of the motivations for making good water management decisions early in the growing season is to reduce risk of root and crown diseases that can eventually kill almond, walnut, prune, and other tree species. Early season water management influences the environment where roots grow by affecting soil temperature and aeration and can be pivotal in how much tree decline actually occurs. Continue reading
This tutorial consists of a single video. In it, we revisit briefly why we offer the weekly crop ET reports. It has been our experience that once growers and crop consultants become familiar with how to apply the weekly crop … Continue reading
This tutorial consists of three videos. We explore how managed levels of crop stress can benefit some crops when employed properly by reducing risk of disease, aiding crop maturity, and optimizing water and energy inputs. We discuss how soil moisture … Continue reading
This tutorial introduces the challenges that soils with variable water holding capacity and uncertainty about effective root zones of crops poses to on-farm water management. We consider how these weekly reports of crop ET can be related to site specific … Continue reading
This tutorial consists of three shorter videos which combine for about 40 minutes of instruction. It focuses on making irrigation decisions in orchard crops during the early years of orchard establishment, as the trees grow from transplants to the early … Continue reading
This tutorial consists of four videos adding up to slightly more than one hour of instruction for growers and consultants. It introduces free weekly crop ET reports. They are heavily geared towards orchard crops and are available throughout the Central … Continue reading
This calculator estimates the maximum weekly hours of irrigation need based upon weekly estimates of crop ET and the hourly water application rate of your system. The maximum weekly hours of irrigation may not be needed because in-season rainfall or soil … Continue reading

“Technology” has different meanings for different people (Figure 1). In irrigated agriculture we look towards technology to meet our changing needs and sustain our industry in the long run. However, with technology, “confusion” and a sense of overload can hinder our ability to learn and apply it. This article considers the abundance of irrigation technology and the challenges with its adoption. Some ideas are offered to cope with the sense of confusion and overload. Continue reading
