Abstract

This study was carried out to runoff characteristics in an upland livestock manure compost. Irrigation, runoff and water quality data in the upland were analyzed periodically from May to November in 2011. The observed amount of rainfall, irrigation, runoff for the experimental upland during the investigation period were 1,299.7 mm, 32.0 mm, and 340.7 mm, respectively. The concentrations of T-N in compost and non-compost upland during study period were ranged from 2.09 mg/L to 6.66 mg/L and from 1.99 mg/L to 6.01 mg/L, respectively. which was generally higher than the quality standard of agricultural water (1.0 mg/L). The concentrations of T-P in compost and non-compost upland during study period were ranged from 0.069 mg/L to 0.525 mg/L and from 0.018 mg/L to 0.152 mg/L, respectively. The runoff pollutants loadings of T-N and T-P in compost upland were 10.05 kg/ha and 0.56 kg/ha, respectively. The runoff pollutants loadings of T-N and T-P in non-compost upland were 9.09 kg/ha and 0.26 kg/ha, respectively. The runoff pollutants loadings in T-N and T-P from this study were much lower values than the pollutant loadings of T-N and T-P from the upland published by the others studies. Runoff pollution loadings due to the upland field in order to identify the characteristics of various crops, farming methods and a variety of targets taking into account regional characteristics by conducting continuous monitoring runoff load estimate will be required.
