(2) Gambut has dark brown to blackish colors. Although its basic materials are gray, brown, or reddish, after decomposition, the dark humic compounds will appear.

Furthermore, based on the weight of the contents, peat soil or gambut, which has undergone further decomposition, has a content weight ranging from 0.2 to 0.3 g/cm⊃3;.

Due to the low content weight, peat has a large capacity as water storage, about 2-4 times its dry weight.

In fact, moss peat that has not been decomposed can store up to 12 or 15 even 20 times more water than its own weight. In addition, peat soil has a large absorption area, which is up to 4 times greater than montmorillonite clay.

(3 )Next, peat soil has acidic reaction properties. Decomposition of organic matters will produce organic acids that accumulate in the body of the soil hence increasing the acidity of the peat soil. Generally, peat soil shows real resistance to changes in pH when compared to mineral soils

As a result, peat soil requires more limestone to increase the pH at the same level of the value of mineral soil. Thus, peat soil requires a higher dose of fertilizers than mineral soil.
