Soil Carbon and Nitrogen Dynamics in a Tropical Peatland

The conversion of peat swamp forest to oil palm cultivation has resulted in the loss of stored nutrients in the peat soil, especially to the atmosphere. Soil carbon and nitrogen are the two major nutrients that are found in large quantities in the peat soil. Therefore this chapter studies the dynami...
