Root mass estimation in lowland tropical rain forests of central amazonia brazil part 3 nutrients in fine roots from giant humus podzols


Root mass estimation in lowland tropical rain forests of central amazonia brazil part 3 nutrients in fine roots from giant humus podzols



Tropical Ecology 16(1): 28-38



ISSN/ISBN: 0564-3295

The immobilization of N, P, K, Ca, Mg and Na by fine roots was studied in giant humus podsols from the Manaus area, Brazil. A decrease of N and P concentrations and an increase of concentrations in K, Ca and Na with increase of root size was found, no clear tendency for Mg was observed. Comparing nutrient concentrations in fine roots from various localities it is evident that concentrations of K, Ca and P in fine roots from Amazon habitats are very low. The amount of nutrients immobilized by fine roots (in kg/ha: 278 N, 5.2 P, 22 K, 35 Ca, 25 Mg, 31 Na) is equivalent to 12, 18, 45, 56 and 76% of the sum of each nutrient in soil + fine roots, or to about 2.4 times the amoutn bound up in the litter layer. The observation that nutrient immobilization by fine roots is greater in the podsols than in the latosols, is probably related to the direct nutrient cycling hypothesis explaining superficial root development in Amazon soils, and rapid nutrient absorption by mycorrhiza, in terms of general nutrient shortage in the Amazon environment.
