DECOMPOSIÇÃO DA BIOMASSA FOLIAR DE CANA-DE-AÇÚCAR EM UM NEOSSOLO NA REGIÃO DE AREIA-PB
The aim of this paper was to study the decomposition velocity of the sugar cane leaf in the own plantation in the Chã de Jardim Farm, belonging to Agrarian Sciences Center/UFPB-Areia, PB.

| description | The aim of this paper was to study the decomposition velocity of the sugar cane leaf in the own plantation in the Chã de Jardim Farm, belonging to Agrarian Sciences Center/UFPB-Areia, PB. It was used 10 g of dry leaves in litter bags measuring 30 cm x 20 cm, being these deposited in the soil superficial and in the depth of 15 cm, with biweekly collections during three months. A subplot design was used with 2 depths, 5 collection times and 3 repetitions. The largest decomposition rates happened in the subsuperficial treatment, mainly in the first 15 days, when it was lost 24.5% of the material, happening a stabilization soon after in the rate of disappearance of the biomass starting from the 30 days. The decomposition in the superficial and subsuperficial treatment followed a standard logarithmic with high correlation coefficient. In the surface, the decomposition rate was slower, having a decomposition peak to the 45 days with 24% of material loss and showing stability starting from 60 days. The superficial decomposition at the end of the experiment was the same percentile reached in the subsuperficial treatment before the 30 days, evidencing, therefore slower decomposition process and nutrients liberation for the soil in larger period. |
