Efeito da arborização de pastagens sobre a fertilidade do solo em Pastoreio Racional Voisin

2018 
This work was carried out in Redentora, Southern Brazil, aiming to evaluate soil attributes inPRV with (PRV-T) or without trees (PRV+T), in comparison to a native forest area (NF). Therewere three replications of the PRV-T and PRV+T treatments, and three replications in theForest Native (FN) area. Soil total organic carbon (TOC), pH, and exchangeable cations (Ca,Mg, Al, K, H, and Al) were quantified, as well as P. Soil samples were collected at 0-5 cm, 5-10cm, and 10-20 cm depths. Data were submitted to ANOVA, and when effects were significant,means were compared by t-LSD at a 5% probability level. The PRV+T had similar performanceto the forest area and improved soil chemical attributes, as compared to PRV-T, with e higherTOC, P and Ca content.
