Rambutan (Nephelium sp.) is one of the tropical fruit plants that are currently being developed intensively. The development of rambutan plants requires land characteristics requirements to support optimal production. The purpose of this study was to examine the limiting factors of land characteristics on the development of rambutan and its management efforts in Lambuea Village, South Konawe. This research was carried out using a land resource survey method which included aspects of land morphology, soil physical properties, and soil chemical properties. The survey was conducted to obtain soil morphological data as well as to estimate the physical properties of the soil in the field and to take samples for analysis in the laboratory to obtain data on the physical and chemical properties of the soil. The observed variables included temperature components (tc), water availability (wa), oxygen availability (oa), rooting condition (rc), nutrient retention (nr), flood hazard (fh), erosion hazard (eh), and land preparation (lp). The results showed that the limiting factors for rambutan production at the research site were mainly land quality related to rooting media, erosion hazards, and nutrient retention. Improvement management to overcome land limiting factors is the addition of organic matter for land units that have a limiting factor of nutrient retention and soil conservation for land units that have erosion hazard limiting factors. Meanwhile, in inland units with limiting factors, the root condition is directed to be used as pasture land or the development of chicken, goat, or cow farms as an alternative source of organic matter.
