Agriculture is the largest user of fresh water globally, and irrigation practices in many parts of the world are biologically, economically, and socially unsustainable: wasting water, energy, and money; drying up rivers and lakes; reducing crop yields; harming fish and wildlife; and causing water pollution. The U.S. Environmental Protection Agency has identified agricultural irrigation as the leading cause of water quality impairment of rivers and lakes in the U.S.. Today's irrigators are struggling to cope with rising energy and water costs at the same time that agencies are working to reduce environmental impacts from irrigation. Sustainable irrigation means applying the correct amount of water at
the right time for optimal crop growth, minimizing overwatering, leaching,
and runoff. Because every farm operation and irrigation system is unique,
standard irrigation training materials tend to fall short of what the
irrigator really needs. The site-specific nature of irrigation generally
requires an on-the-ground approach, one that begins with an audit of the
hardware and management techniques actually being used. NHT irrigation
specialists know how to help irrigators save water and energy, reduce
power bills, and optimize crop yields. We have special expertise in conducting
energy audits of pumped irrigation systems. Our auditors use ultrasonic
flow meters to quickly and accurately measure flow rates and calculate
pumping plant efficiency. We inspect the entire irrigation system to identify
cost-effective hardware improvements. We can also design irrigation efficiency
training programs for groups or individuals, and we have extensive experience
with soil moisture monitoring systems and weather station-based approaches
to irrigation management.
