SOIL AND FOLIAR NUTRIENT RELATIONSHIP IN SELECTED <em>SHOREA</em> AND <em>KOOMPASSIA</em> SPECIES IN TWO FOREST RESERVES, PENINSULAR MALAYSIA

Abstract

We analysed the soil and foliar nutrient relationships of two lowland tropical rain forest trees. Koompassia spp. contain higher foliage nutrient concentrations for N, K, Ca and Zn than Shorea spp. Significance differences between soil and foliar K is established for both species. Foliage in trees growing on fertile soils had higher nutrient concentration compared to those on less fertile soils. Koompassia spp. accumulated a higher concentration of nutrients than Shorea spp.
