Poultry litter is an important nutrient source in agriculture, although little information is available regarding its decomposition rate and nutrient release. To evaluate these processes, poultry litter (PL) was applied to the soil to supply 100, 200 and 300 kg ha-1 N contained in 4,953, 9,907 and 14,860 kg ha-1 PL, respectively. The litter bag technique was used to monitor the process of decomposition and nutrient release from the litter. These bags were left on the soil surface and collected periodically (after 15, 30, 60, […]

With the prevalence of no-till systems in Central-Western Brazil, a more in-depth knowledge about cover crops for straw production is necessary. The objective of this study was to evaluate the green and dry biomass production, the percentage of soil cover, as well as the dynamics of residues decomposition of three cover crop species, in the second growing season of the cropping year: amaranth (Amaranthus cruentus L. BRS Alegria), pearl millet (Pennisetum glaucum L. var. ADR500) and finger millet [Eleusine coracana […]
