Description:
Twelve 6 x 6 meter plots were designed to receive overland spray or rainfall only and sloped to direct runoff via plastic lined runoff ditches to one cone shaped plastic lined corner of each plot. These plots were completely randomized over all treatments each treatment having four replications. Treatments consisted of tap water, tap water and aerobic effluent, and aerobic effluent applied so that all plots received equal volumes of overland spray within each of three periods. Periods one, two and three provided 1x, 2x, and 3x as much of the applications on all plots than before treatments. Soil and soil water samples from all plots were analyzed for pH, chloride, NH3-N, NO3-N, and NO2-N, conductance, coliform, and BOD5. These parameters were statistically analyzed according to a completely randomized block design and the means separated for significance using DNMRT. Reduction or increase in principal parameters of concern were noted, as well as response of edible crops to various treatment.
