Manure Effects on Water Intake and Runoff Quality from Irrigated Grain Sorghum Plots1

Feedlot manure was incorporated into Pullman clay loam at rates of 0, 22, and 67 metric tons per ha annually (tons/ha/per year). Additional treatments were 67 tons/ha manure the first year only and 224-kg N/ha/per year as anhydrous ammonia. The time required for irrigation water to advance down graded furrows was increased by the manure treatment. Also water intake and grain yields were higher on manure- than on ammonia-treated plots. Runoff quality was not markedly reduced by manure treatments as indicated by NO3, P, and Cl concentrations in the runoff water.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
