Mountain Research and Development v. 3, no. 4, p. 338-345617588Summary: Large test plots were constructed for soil erosion and conservation determinations on steep mountain slopes (54% grade) at an altitude of 1240 m. The 24X5-m test plots were planted with a mix of traditional swidden and introduced agroforestry systems crops at Mae Muang Luang, Huai Thung Choa research area, 75 km NW of Chiang Mai. During 1981 comparisons were made of runoff, soil loss, labour input, and crop yield. Annual soil losses from agroforestry test plots were 10-22 t/ha or 4-9 times lower than from traditionalupland rice (89 t/ha). Labour inputs were 50-150% higher, but subsistence crop yields were comparable despite a reduction in cultivated area.
