Analysis of Soil Primary Macro Nutrient Status in Agricultural Land, Tabundung District, East Sumba Regency

Agricultural land is that can affect agricultural productivity. Land, which part of resources, the main component in production commodities. In supporting productivity commodities, there must be sufficient nutrients soil. Tabundung sub-regency a producer food crops, livestock and fisheries. As sector, crops not proportional to total area harvested land, meaning optimal if it based on area. The study was conducted Tarimbang Village, Proud Watu Tapil Regency Tabundung. method used this research survey technique soil sampling carried out composite manner. Soil samples were analyzed at Nusa Cendana University Laboratory, Kupang. Primary data elements nitrogen (N), phosphorus (P), potassium (K), organic carbon (C), cation exchange capacity (CEC), pH. results showed overall nutrient status N, P, K medium, high very categories, but some sample points low category for macronutrients N P. While concentrations C, CEC pH generally pretty good condition. This condition indicates provides plant cultivation during growth yield plants, improvements are needed overcome macronutrient deficiencies several observation locations.
