Improving Soil Quality with Gypsum for Agricultural Sustainability
Abstract
Gypsum is a substance derived from nature and some synthesis. Its structure
consists of calcium ion (Ca2+), sulphate ion (SO4
2-) and molecules of H2O. Its formula is
CaSO4.2H2O. From this structure, gypsum is used in agriculture as soil conditioners,
especially acid soil and saline soil. The calcium ion will replace aluminium ion (Al3+) in
acid soil and sodium ion (Na+) in saline soil. It is effective to reduce acidity, salinity,
compaction in soil and increase friable condition which is suitable for agriculture.
Moreover, calcium and sulphur are the secondary nutrients for plants. Therefore, the
application of gypsum as soil conditioners will reduce soil deterioration, increase
agricultural profits, conserve of soil, relieve problem of agricultural areas and maintain our
agricultural sustainability
