Abstract

Litter decomposition plays an important role in releasing nutrients back to the forest. The decomposition rate is affected by several factors, namely soil biota, climate, site condition, physiochemical properties and litter quality. The present study is conducted to compare the decomposition rate and nutrient release patterns in three different forest types in Universiti Putra Malaysia Bintulu Campus, namely Plantation Forest (PF), Rehabilitated Forest (RF) and Logged-over Forest (LF). Decomposition rates and nutrient release pattern were similar for all three study sites. The RF recorded the highest values of weight loss. Decay rates, k were recorded between 0.1050 and 0.1196 per annum. Nitrogen loss was slow initially and increased after four months while potassium was released more rapidly than phosphorus. Significant differences detected for nitrogen and potassium release rate suggested the microbial activity may be the main contributor influencing the rate of decomposition and nutrient release patterns.
