CONCENTRATION AND REDISTRIBUTION OF NUTRIENTS IN THE LEAVES AND IN THE LITTER OF Acacia mearnsii De Wild. STAND AT IN RIO GRANDE DO SUL STATE

This work aimed to study the concentration and the redistribution of mineral nutrients in the newly mature leaves and in the litter, in a three years old Acacia mearnsii De Wild. forest, planted in soils with low fertility in Rio Grande do Sul State. Among the mineral elements analysed nitrogen had higher concentration in the newly mature leaves as well in the litter. Phosphorus and potassium were the nutrients more retranslocated. However, calcium was the element that presents had the smaller retranslocation.
