Soil Quality Evaluation and Land Management Directions on Dry Land in Sawan District, Buleleng Regency

Abstract

Intensive land use without conservation efforts leads to a decrease in soil quality and a decrease in production yields. The purpose of the research is to evaluate soil quality, determine limiting factors, and provide appropriate land management directions according to soil conditions in Sawan District.
