West Nusa Tenggara (NTB) and East Nusa Tenggara (NTT) Provinces covered an area of about 6.6 million ha, of which largest part (95%) categorized has dry-climate with annual rainfall 2,000 mm rainfall that lead to high leaching. Soil texture may influence water content where the higher sand portion of soil, the lesser capacity to hold water and nutrients. Fertility status of the three islands is quite good but low in organic carbon content which indicated special attention to improve soil quality. Thus the land management of upland dry-climate area should be focused on surface water availability and conservation agriculture.
