THE POTENTIAL LAND FOR PLANTATION IN NORTH MINAHASA REGENCY

JOICE M. J. SUPIT

Abstract

Indonesia has wide area with variable land resources characteristics, so that appropriate plantations in each area are different. North Minahasa is a relatively new regency in Indonesia that needs data of the potential land for plantation to guide the development planning policy. Aims of the research were to identify land resources characteristics, to do the mapping of the potential land for plantation, and to give recommendation for the regency for development planning policy in North Minahasa. This research were done by field surveys and resources characteristics analysis which were consisted of the chemical and physical properties of the soil, also the physicals of the environment. Interpretation results were disclosed by potential land map using GIS Arcview. The results showed that in North Minahasa, the chemical properties were low to very low soil nutrients. At the same time, the physicals of the environment have climate type B1, C1, C2, D1, D2, and E2, land slopes were 0-45% and heights were 0-1.975 mamsl. Based on the results, the potential main plantation crops to develop in North Minahasa were coconut, clove, nutmeg, and vanilla, whereas the potential supporting crops were coffee, cocoa, sugar palm, cashew nut, cassiavera, and jatropha. Low to very low soil nutrients can be treated with fertilization, whereas the land slope >25% and heights >500 mamsl can be resolved by employing the land conservation factors and plantation ecology. At present, plantation species in North Minahasa are consistent with the recommendation of this research, however, rejuvenation of the old plants was needed.
