Decomposition of leaf and fine root residues of three different crop species in tropical peat under controlled condition.

A study examining the decomposition rates of leaf and fine root residues of oil palm (Elaeis guineensis), sago (Metroxylon sagu) and pineapple (Ananas comosus) crops in peatland soils was conducted under controlled conditions. The fourteen- month study showed that sago leaf residue was the most resi...
