Perubahan Beberapa Sifat Kimia Tanah Sulfat Masam Delta Telang, Musi Banyuasin, Sumatera Selatan Akibat Pengeringan Dan Pencucian
Abstract
Acid sulphate soil having oxidized pyrite layer is hard to be used for agriculture. This soil has several ions namely H-, Fe2+, SO42- ,that may be toxic for plant if they are in a large amount or high concentration, which happen when pyrite oxidized. A high acidity caused by pyrite oxidized will increase Al3+ and Mn2+ solubility. The high concentration of toxic ions is the main problem at actual acid sulphate soil. This problem can be solved by leaching methode.
