Abstract

Cultivation of crops in strips following the contours of the land to minimize erosion is a well-established conservation practice. This study was conducted to measure the effectiveness of a narrow wheat strip in reducing runoff nutrient transport from plots with a range of soil nutrient values. Beef cattle manure was applied to a silty clay loam soil at rates needed to meet a zero, one, two or four year corn P requirement. Three 30 minute simulated rainfall events, separated by 24 hour intervals, were applied. Excessive amounts of manure were added after the initial tests were completed to meet 8, 12, 16 or 20 year corn P requirements to determine the effects of excessive manure application on runoff nutrient transport. The effects of a narrow wheat strip, manure application rate, and runoff rate on nutrient transport were determined using ANOVA. The wheat strip significantly reduced the mean transport of DP, NO3-N, NH4-N, and TN in runoff. The wheat strip also reduced EC of runoff, particularly when excessive amounts of manure were applied. Manure rate significantly affected measurements of DP, PP, TP, NH 4-N, TN and EC. Runoff rates significantly affected each of the measured runoff water quality parameters. When manure was applied to meet the 8, 12, 16, or 20 year crop P requirements, DP, PP, TP and NH4-N transport generally increased as application rates increased. The results indicate that wheat strips can reduce N and P transport in runoff.
