Irrigation第 22 / 100 题
Cycling a station into several short run times instead of one long run is called cycle-and-soak and mainly prevents what?
a.Clogged nozzles
b.Low water pressure
c.Runoff on soils with slow intake or on slopes
d.Freezing pipes
解析
Cycle-and-soak breaks a long irrigation into shorter bursts with soak periods between, letting water infiltrate before more is applied. This prevents runoff when the precipitation rate exceeds the soil's intake rate, common on clay soils and slopes. It improves efficiency without changing total water applied.
