Analysis of land productivity based on soil fertility in cocoa plantation land in Campalagian district, Polewali Mandar Regency

Abstract

Abstract Potential areas for developing certain commodities can be determined by using the index value of land productivity. This study aims to analyze the land productivity of Campalagian District based on soil fertility level for the development of cocoa plants. The quantitative research method uses the Storie equation in determining the value of the land productivity index. Determination of observation points based on purposive sampling method. Soil properties determined in the field and the laboratory, including slope, effective depth, texture, pH, C-Organic, N-Total, P2O5, CEC, and the number of interchangeable bases. The results of the analysis of the land productivity index of the Campalagian district are classified as bad to good, with land productivity index values ranging from 13.89 to 51.37, with limiting factors, namely slope, effective depth, texture, C-Organic, and N-Total.
