Soil erosion in different cultivation methods of the buffering zone of the Ba Vi National Park, Ha Tay province
Research on soil erosion was carried out in 7 different cultivation methods, leading to conclusions: forest trees i.e. Pine, Acadia with good coverage had diminished surface water flow from 74.0 -92m3 while it occurred by up land rice, cassava and Leucaena with 120-140m3/ha/one rain/month. Cultivation method with low water surface followed also by low eroded soil loss, and was from 48-62% of the control. The water brought away a large amount of nutrients.
