Effect of Mowing Height Upon Consumptive Water Use, Groundwater Recharge and Recharge Quality from Bermudagrass Watered with Secondary Treated Effluent

摘要

Tifgreen bermudagrass was grown on three soil mixes (washed mortar sand, 95 sand - 5 zeolite, 90 sand, 10 zeolite) under three scheduled mowing heights (12.5, 25.4 and 37.5 mm) and irrigated with secondary sewage effluent at 100% Class A Pan evaporation (less rainfall) twice each week. Because of certain growth problems the height differentials were not fully established the first year, but water use was consistently less over the period June 1982 - June 1983 for the 12.5 mm height treatment than for the other two. Adding zeolite had no apparent effect on water use. The turf received no nutrients other than those supplied by the effluent.
