Research was aim to make map of soil fertility status and its management on farmland in Plain of Waeapo, Buru Island have been conducted at 25.400 ha area, in year 2000. Evaluate of soil fertility status conducted in each soil-mapping unit and delineated with landscape mapping approach. Result of research that soil fertility status in Plain of Waeapo is very low, low, middle and high, with wide respectively 17.145, 5.182, 1.549 and 1.542 ha. Limiting factor to soil fertility is lowering of cation exchange capacities (CEC), C-Organic, K2O, P2O5 and base saturation. Alternative of land management suggested is improving C-organic and CEC which at the same time also can improve soil nutrient content by giving organic materials like manure, straw compost (rich of K), chicken waste and guano (rich of P), accompanied with giving of inorganic manure like N, P, and K pursuant to soil chemical analysis. At area with landform undulating to hilly needed conservation act, while mangrove forest, river border forest and sago which is damage to be rehabilitated, while which still natural to be defended.
