The application of animal manure to soil can increase phosphorus availability to plants and enhance transfer of the nutrient solution drained from the soil surface or leached into the soil profile. The aim of this study was to evaluate the effect of successive applications of organic and mineral nutrient sources on the available content, surface runoff and leaching of P forms in a Typic Hapludalf in no-tillage systems. Experiment 1 was set up in 2004 in the experimental area of […]

In a no-tillage system, cover crops must be used that combine shoot dry matter production and nutrient recycling. The aim of this study was to evaluate shoot dry matter production, decomposition rate and macronutrient and silicon release from pigeonpea and pearl millet in monoculture and intercropping systems. A randomized block design was used with a 3 x 6 factorial arrangement, with four replications. The first factor consisted of three cover crops (pigeonpea, pearl millet and intercropping of these cover crops) […]

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 […]
