Participants will be provided with a summary of the major irrigation systems including recent advances and their utility.
Irrigation has been central to agriculture for over 5,000 years. Irrigated agriculture covers only about 15% of cropland in the U.S., but provides more than 45% of agricultural products. Irrigated agriculture is a major user of ground and surface water, accounting for approximately 80% of the Nation's consumptive water use and over 90% in many western states. There are four primary types of irrigation systems: surface, sprinkler, drip or trickle, and subsurface. Some recent technological advancements in these systems have been introduced to enhance performance, ease management, and reduce energy use, or meet other specific needs. In the past few decades, changes to irrigation systems have been mostly in greater system and component robustness, improved application technology with higher precision, and enhanced automation/control. System operation and management have been substantially improved via readily available GPS and affordable remote communications and real time data availability. This webinar is expected to be of value to most field staff, especially since most systems discussed in this webinar are financially and technically supported by USDA NRCS.
This webinar is presented by USDA NRCS Science and Technology.
