Irrigation With Simulated Secondary Waste Water on Tiled Soil Cropped to Bromegrass and Corn¹

ABSTRACT

Simulated secondary municipal waste-water effluent was applied by sprinkler irrigation for a 6-year period to a tiled soil cropped to bromegrass (Bromus inermis L.) and corn (Zea mays L.). The effluent was applied at two rates, 100 and 200 cm season^–1, and efficacies of additional N and K fertilization were also tested. The concentrations of both PO₄-P and NO₃-N in the drainage water were lower under grass than corn; however, the nutrients removed by corn were greater than by grass. Additional N fertilization of corn significantly increased nutrient removal, but K fertilization did not. The concentration of P and K in tile water varied with time of outflow, the peak concentration of nutrients preceding by hour the peak outflow of water.

Key Words: waste-water irrigation • waste-water renovation • drainage • nutrients • crops
