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.

Surge Irrigation Information from U of A

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
