Soil quality under acacia mangium plantation in Nanga Lajan, Song

Acacia mangium is widely planted as plantation species in Sarawak due to rapid changing in deforestation activities such as logging and clear cutting henceforth to accommodate the supply of raw material timber for industrial purposes. A. mangium has been chosen as a number one species planted in Sar...
