An acidic (pH 4.0) Typic Tropohemist of Basey, Samar with very high (69 percent) organic matter content was tested for lime and cropping response using mungbean, upland rice and corn. Results revealed the positive effect of liming (5 tons dolomite/ha) in the nuetralization of soil acidity even during the first cropping. However, growth and yield of all test crops remained unaffected by lime application until the second cropping period where significant yield increase of mungbean and corn were noted. Similar effect was observed in the succeeding cropping periods until the prolonged drought which hit the area towards the third cropping year. On the contrary, upland rice consistently gave insignificant growth and yield response throughout the whole cropping seasons indicating its inherent adaptation to the prevailing acidic peat soil environment. Between relay (mungbean-upland rice-mungbean-corn) and monoculture croppings of the same set of crops, it was found out that relay cropping is in a way environmentally and in most cases economically better than the monoculture scheme
