tailieunhanh - Assessment of soil loss from agricultural lands of south Andaman district in tropical islands

Soil loss was estimated from agricultural lands of South Andaman district in tropical Bay Islands applying Universal Soil Loss Equation (USLE). Mean annual rate of soil loss to the tune of X 103 tons was estimated from the crop fields of the district covering ha area at the rate of t ha-1 yr-1 . In South Andaman district, kharif crops (rice, maize, arhar, ground nut, ginger, sweet potato, tapioca and turmeric) are grown in medium to low lands whereas rabi crops (pulses and vegetables) are grown in uplands. The cropping intensity is . Maximum ( thousand tons) and minimum ( thousand tons) soil loss was obtained from the cultivation of vegetables ( ha) and arhar ( ha), respectively. The highest ( t ha-1 yr-1 ) and the lowest ( t ha-1 yr-1 ) rate of soil loss were obtained from the cropping pattern of rice-fallow-fallow and gingerfallow, respectively. Among the double cropped land, the sequence of sweet potatovegetable-fallow contributes the lowest rate of soil loss ( t ha-1 yr-1 ), whereas the cropping sequence of rice-fallow-vegetable yielded the highest rate of soil loss ( t ha -1 yr-1 ). The average rate of soil loss from double cropped land is t ha-1 yr-1 . The study reveals that converting more mono crop area into double cropped land will reduce the average soil loss annually by . | Assessment of soil loss from agricultural lands of south Andaman district in tropical islands
