Tropical peatlands have very diverse physical and chemical properties. Its characteristics are largely determined by the thickness of the peat, the substratum, the mineral soil beneath it, its maturity, and the presence or absence of enrichment from overflowing rivers in the vicinity. The characteristics of peatlands are usually used as a reference in their use to achieve high and sustainable productivity. In accordance with Presidential Decree No. 32/1990 concerning the management of protected areas, peat with a thickness of >3 m is designated as a conservation area. This is because the thicker the peat layer, the more fragile the peat will be. Peat with a depth of <3 m can be used for agriculture provided that the mineral layer under the peat is not quartz sand or pyrite clay, and the peat maturity level is not fabric.
