Evaluation of Land Suitability for Mangosteen and Its Potential for Development in Pauh District, Padang City
Evaluasi Kesesuaian Lahan untuk Tanaman Manggis dan Potensi Pengembangannya di Kecamatan Pauh Kota Padang
Mangosteen has potential in the field of economics, statistics record crops of fruit and vegetables in 2015 that mangosteen exports reached a value of USD 17,2 million. This value encourages the government of West Sumatra to develop mangosteen as an effort to increase revenue and the local economy through Nagari Mandiri Pangan. Pauh District was chosen as mangosteen plantation development centre in Padang City. This development should be based on the land suitability so that the mangosteen plant are able to grow according to the climate and soil conditions. This research was conducted in Pauh District, Padang City and Soil Science Laboratory, Faculty of Agriculture, Andalas University. This study used a survey method that consisted of preparation, pre-survey, the main survey, laboaratory analysis, and data processing. Evaluation of land suitability was done with matching method which compare the characteristics of land suitability for mangosteen growth. The results of the research showed that land suitability for mangosteen was classified into S3 (marginally suitable) with subclass S3nr with limiting factor was nutrient retention for land unit SL1, SL2, SL3, SL4, SL7, SL8, SL9, SL11, SL15; subclass S3eh with limiting factor was erosion for land unit SL14; subclass S3nr,eh with limiting factors were nutrient retention and erosion for land unit SL5 and SL10. Land unit SL6, SL12, SL13, and SL16 were classified into S2 (moderately suitable) with subclass S2wa,nr with limiting factors were rainfall and nutrient retention for land unit SL6 and SL16; subclass S2wa,rc,nr,eh with limiting factors were rainfall, soil depth, nutrient retention, and erosion for land unit SL12; subclass S2wa,rc,nr with limiting factors were rainfall, soil depth, and nutrient retention for land unit SL13. The limiting factors was common to each land unit were nutrient retention (nr) and erosion (eh). There are 3 villages (Lambung Bukit, Limau Manis, and South Limau Manis) in Pauh District which have the greatest potential to be developed as mangosteen plantation development areas with total area was 5862,42 ha.
