Dry matter dynamics, storage and flux of nutrients in an aged eucalypt plantation
Abstract
The net primary productivity and nutrient cycling in a 25-yr-old eucatypt plantation has investigated and compared with an 8-yr-old eucalypt plantation (rotation period for the region) and adjacent natural forest. The biomass of 25-yr-old plantation was two times higher than of 8-yt - old plantation but the primary productivity values were similar. The nutrient return to the soil throught litter fall and decomposition rate of leaves were higher than that of 8-yr-oid plantation. The nutrient concentration in the soil of 25-yr-old plantation was higher than that 8-yr-old plantation and lower than that of adjacent natural forest.
