Soil analysis
Seven soil chemical parameters were analysed
1. Total nitrogen, N
2. Total phosphorus P
3. Total Potassium, K
4. Total Magnesium Mg
5. Total Cation exchangeable capacity CEC
6. Available phosphorus
7. Soil pH
Reffered to Amir Husni 1994 as cited in zahari salleh 1994 These parameters were found to be significantly correlated with species pattern in a study on a lowland dipterokarp forest in Jangka and Tekam Forest Reserve
An automic absorbtion spectrometer was used to determine total K and Mg, while an auto-analyzer was used to determine total P, total n and total CEC. For P available, a spectrophotometer at 882 nm was used.
