Abstract

Land suitability evaluation is very important in the process of matching land types to specific uses. This study aims to make a map of the distribution of land suitability classes for mango plants in South Langowan District by utilizing Spatial Technology. This research was conducted using field survey and geoprocessing methods. Data collection techniques are documentation, observation, and laboratory analysis. Determination of land suitability classes using the method from FAO, namely matching the observation variables there the conditions for growing mango (Mangivera indica L.) plants and land quality/characteristics. In this study, 30 land map units covering an area of 4910.82 Ha were obtained which were spread over several villages in South Langowan District. The resulting land suitability class map is S1 land suitability class (Highly suitable) for nutrient retention criteria and available nutrients. While the criteria for temperature and rooting media are included in the land suitability class S2 (Moderately suitable) and for the criteria for water availability and the level of erosion hazard are generally included in class S3 (Marginally suitable). While the level of erosion hazard is a criterion that gives class N (Not suitable) for mango plants in 12 (twelve) land mapping units with an area of 258.16 Ha or around 5.26%. Meanwhile, 18 (eighteen) land mapping units covering an area of 4652.66 Ha, or around 94.74% are suitable for the development of mango plants.
