Abstract
Sediment and nutrient loading caused by the forest to conversion of agricultural lands have led to the deterioration in near water ecosystem. This study was carried out to examine the effects of agroforest culture field and open field culture field on water quality and runoff loading of nutrient. The runoff loading of Tot-N and Tot-P in agroforest culture field were similar to open field culture field. The runoff loading of total suspended solids (TSS) in agroforest culture field and open field culture field were $2,721kg{\pm}196/10a$ and $420{\pm}29kg/10a$ in 2011 and $696kg{\pm}59/10a$ and $463{\pm}36kg/10a$ in 2012, respectively. Our investigation showed that the runoff loading of TSS from agroforest culture field decreased when soil cover and soil stabilization increased. Therefore, protect facility of soil erosion for early alteration of agricultural lands are needed to minimize the soil erosion from agroforest culture field.
