Land Suitability of Agroforestry Components in Tompo Bulu Village, Bulupoddo District, Sinjai Regency

Abstract

Plants have unique growing needs for optimal growth. Unfortunately, land expansion, reduction in fertile agricultural land, and errors in selecting plant types of hamper agroforestry development. This study was carried out in two stages of activities: field activities and laboratory analysis. Field activities were carried out in Tompo Bulu Village, Bulupoddo District, Sinjai Regency. Laboratory analyses were carried out at the Silviculture and Tree Physiology Laboratory of Forestry Faculty, Hasanuddin University. This study aims to evaluate land suitability for agroforestry. The land is compared with ideal criteria for the crops planted (pine, cocoa, coffee, cloves, nutmeg, sugar palm, rambutan, mahogany, teak, and banana). The results show that land suitability varies from marginal (S3) to unsuitable (N). The main limiting factor is the very low soil pH. However, this obstacle can be overcome by liming or adding organic materials.
