Abstract

Information on land characteristics, especially climatic and soil conditions of an area, is not only needed in determining land suitability but also in determining alternative management inputs needed for the development of certain commodities, including rubber and oil palm. Rubber and oil palm are export commodities that are national priority whose productivity continues to be pursued, including through extensification to various regions. This study aims to determine the potential for the development of rubber and oil palm plantations in Moramo and surrounding areas, based on soil and climatic conditions. Soil survey method which aims to obtain land characteristics data is used in this study. The characteristics of the land observed were climatic conditions such as temperature, rainfall, and dry months, and soil conditions such as drainage, texture, effective depth, cation exchange capacity, base saturation, pH, C-organic, P2O5, K2O, surface rocks, erosion hazard, slopes, and flood hazards. Evaluation of land suitability was carried out using the matching method between land characteristic data obtained from the field and laboratory with the criteria for growing rubber and oil palm plantations. The results showed that the climatic conditions that could be a limiting factor for the development of rubber and oil palm plantations in the Moramo area were rainfall and air temperature. Soil conditions that are limiting factors for the development of rubber and oil palm plantations in the Moramo area can be in the form of effective soil depth, slope, and erosion hazards. Management inputs that need to be carried out for the development of rubber and oil palm plantations in the Moramo area are soil conservation measures for erosion and slope limiting factors, and irrigation system settings for rainfall limiting factors. Potentially based on climate and soil conditions, rubber and oil palm plantations have the potential to be developed in most areas of Moramo.

Abstract

Soil characteristics determine the potential yield of cultivated plants. Soil morphological characteristics generally differ between depths and locations, so different management efforts are required. This study aimed to determine the morphological characteristics of the soil in each layer and between sub-districts on upland rice cultivation land in North Buton Regency. The research method is based on free survey observations with an area administration approach to upland rice cultivation. Soil observation is carried out by drilling. Drilling is carried out to a depth of 120 cm or up to a layer of soil parent material. Qualitative soil descriptions have been carried out directly in the field to obtain an overview of soil morphological characteristics between layers and locations. The results showed the morphological characteristics of the soil on upland rice cultivation in North Buton Regency, where soil colors are generally brown (ranging from dark brown to yellowish brown; Hue 7.5-10 YR with low value and chroma respectively). Soil texture generally includes fine to medium texture, ranging from clay, silt to loam, except for the slightly coarse-textured Bonegunu area (sandy loam) in the subsoil layer. Soil consistency generally includes firm in moist conditions, plastic and sticky in wet conditions. Soil organic matter content is generally moderate, except for the Kambowa area which is low. While the soil pH levels, both between depths and locations, are in the slightly acidic category. It is necessary to pay attention to the differences in pedogenesis factors between locations in the management of upland rice cultivation in the North Buton Regency to realize optimal and sustainable productivity.
