Immobilization of nutrients in plantation forest of Pinus merkusii and Agathis dammara growing on volcanic soils in central Java, Indonesia
1984
Bruijnzeel, L.A.
Growth of P. merkusii is better than for Agathis, especially during the first 15 years. The effect is species determined rather than caused by differences in site class. Nutrient uptake by the typically over-stocked pine plantation was significantly less than for the normally stocked Agathis stand. It is concluded from a comparison of gains and losses of nutrients for these ecosystems that whole-tree harvesting of Agathis should not be practised in central Java, whilst this would be feasible from a nutrient point of view for the pine forest site. The limiting nutrient for sustained production of Agathis is P and possibly N in the case of P. merkusii. Care needs to be taken to control nutrient losses via erosion during taungya
