Effect of peat solidification on macronutrients in soils associated with palm oil plantation in peat area
Nutrients in the soil either from man-made fertilizers or natural are factors that affect the chemicals in the peat soil stabilization through leaching. The study aims to identify the concentration of elements and nutrients on peat solidification of cement (OPC), fly ash and bottom ash. Lab scale ph...
