Land erodibility and land use directions in krueng seulimum watershed aceh province

Abstract

Purpose – The purpose of this research is to to determine the value of land erodibility in Krueng Seulimum watershed. Design/Methodology/Approach – This research apply survey method and field measurement that begins with making land unit map. Findings – The results showed that Krueng Seulimum watershed consisted of 22 units of land (LU). The value of land erodibility in secondary forest land use is low, i.e., 0.13–0.19 (LU 13 and 22), the value of land erodibility in grazing lands land use is medium, i.e., 0.31–0.32 (LU 9 and 11), the value of land erodibility in scrub lands land use is rather high, i.e., 0.33–0.35 (LU 2, 6, 12, 15, and 19) and the value of land erodibility in dry land agriculture land use is medium – rather high, i.e., 0.28–0.35 (LU 3, 7, 10, and 16). Research Limitations/Implications – The land use directions for scrub lands is for cocoa-based mixed crops, such as cocoa monoculture, cocoaþareca nut, and cocoaþbanana. Practical Implications – The use of dry land agriculture is maintained for land use coupled with agrotechnology action that is guludan terrace plus mulsa application. Originality/Value – Most of the soil in the Krueng Seulimum watershed has very low soil fertility level that affects nutrient availability plant. These characteristics should be considered in the direction of land use in the Krueng Seulimum watershed.
