The objective of this study was to measure the dynamics (immobilization and release) of N and to avaluate the effect of the initial chemical composition of four Panicum maximum cultivars grown in a Alfisol and fertilized with different levels of nitrogen (0, 80 e 160 kg ha-1 de N) and phosphorus (0 e 200 kg ha-1), on the release of the N from the litter using the litterbags technique. There was an increase in the litter initial concentration of N with time of decomposition. The Aruana and Vencedor cultivars released about 70 and 60% of N; respectivelly, during the decomposition of the litter from 0(zero) to 336 days; the Tobiatã and Tanzânia cultivars released about 30 and >30% of N from the concentration of the initial litter respectively. Nitrogen fertization increased the N release, up to 20% in the highest N level tested (160 kg ha-1 of N). |
