Abstract
Longterm integrated croplivestock system enables constant and more efficient nutrient cycling because animal pasture and crop residues release nutrients at different rates Therefore appropriate management of these systems is needed to maximize benefits from nutrient cycling The objective of this study was to evaluate how grazing intensity affected the release rates of phosphorus P and potassium K in pasture dung and soybean residues in a notill longterm integrated croplivestock system The experiment was established in 2001 on a clayey Oxisol after soybean harvest Treatments consisted of pasture with sward heights maintained at 1020 30 and 40 cm by different cattle stocking rates and a nongrazed NG treatment Decomposition and release rates of nutrients in the pasture and dung were determined using litter bags which were installed at soybean seeding and pasture seeding during two pasturecrop cycles 2009–2011 Lighter grazing intensities resulted in greater P release rate from pasture and dung residues Pasture and dung residues released K at a very high rate and were not influenced by grazing intensity The P and K released from soybean residue were not affected by grazing intensity however decomposition of soybean leaves was greater than of stems Greatest rates of total P and K released were from pasture and dung residues under lighter grazing intensities and in the NG areas Large amounts of P ~25 kg ha−1 and K ~130–180 kg ha−1 were cycled in a complete soybeanbeef cattle integrated system and must be considered in the fertilization managementWe would like to thank Adao Luis Ramos dos Santos for the support provided in the laboratorial analysis and field activities We also thank the National Council for the Development of Science and Technology CNPq and the Coordination for the Improvement of Higher Education Personnel CAPES for financial and scholarship support
