An update on zero burning in land clearing for oil palm newplanting.
Techniques developed for forest clearance without burning, preparatory to planting oil palms [Elaeis guineensis] are described and discussed, based on experiences in Malaysia. The techniques were developed with a view to maintaining soil fertility, ensuring nutrient cycling from decomposition, controlling erosion and protecting the environment. Clearing was done in 3 land categories: light, with secondary forest and underwood; medium with trees of 30-80 cm circumference; and heavy - logged areas with trees of circumference80 cm. Mechanical felling was done where possible, with manual felling in areas inaccessible to bulldozers. Residues were stacked mechanically (with a bulldozer) straight after felling or later, in an alternate (oil palm) planting row pattern. Designs are outlined for road design and moisture conservation practices using terraces. Leguminous cover crop planting was necessary, with Mucuna cochinchinensis greatly accelerating slash decomposition. Palm planting techniques are outlined. The procedures described will be adopted in heavy density areas in Kalimantan Timur (East), Indonesia, and Pahang, Malaysia.
