When using a surge valve, water is applied in a series of on-off cycles alternating between two irrigation sets. By utilizing surge valves, growers can expect reduced surface runoff, reduced deep percolation loss and 25% greater application efficiency compared to conventional irrigation. On sealing silt loam soils improved infiltration rates have been documented. Understanding the correct operation procedure and purchasing the correct surge valve is imperative to the success of deploying a surge valve.
What is Surge Irrigation? Surge irrigation is the intermittent application of water used to improve distribution uniformity along a furrow. It works on the principle that dry soil infiltrates water faster than wet soil. When soil is wet is seals because the soil particles at the surface consolidate. When water is re-introduced in a furrow… Read more
The goal of this document is to help farmers and other interested parties understand the economics of irrigation efficiency improvements in furrow irrigation. Irrigation using surge valves in furrow irrigation is the focus of this analysis. Surge valves in furrow irrigation are used to run water down the field with on-and-off cycles of water delivered… Read more
In 2014, the Irrigation Team added surge valves to our list of tools to increase irrigation application efficiency. When using a surge valve, water is applied in a series of on-off cycles alternating between two irrigation sets. By utilizing surge valves Producers can expect reduced surface runoff, reduced deep percolation loss, and application inefficiencies 25%… Read more
