The decomposition rate constant f the oil palm residues ranged from 0.13% to 0.22% day-1 in which the leaflets, rachises, trunks and roots had a value of 0.22%, 0.17%, 0.17% and 0.13% day-1 respectively. The controls regulating decomposition of oil palm residues during the study period have been shown to operate in the rank order: macroclimate > microclimate > resource quality > organisms.

The oil palm empty fruit bunch (EFB) is one of the major waste products of the oil palm industry and is currently used as an organic mulch in young and mature oil palm plantations. A field experiment was set up to monitor EFB decomposition and N and K release for a period of 10 months with the EFB placed in single or double layers stacked along mature oil palm interrows with and without inorganic N and K fertilizers.

Currently, most of the EFBs (empty fruit bunches) that come out of the mill as waste are used as an organic fertilizer for oil palms. An experiment was conducted to study the decomposition of EFBs applied single-layered or double-layered under oil palm field conditions, and to investigate the availability of N as a result of mineralization in 15 weeks period.

Nutrients released from oil palm residues showed different release patterns between residue types and nutrients. The leaflets, rachises, trunks and roots all showed nutrient release in the order: K>Mg=Ca>P>N. The release of nutrients from the residues was relatively quick, especially K, with more than 70% of the nutrients released.
