“…Grazing was performed by three girolando heifers, each with a 300 kg body weight. The grazing period started when the canopy had a 90-cm height and ended when it had a 20-cm height, as suggested by Fidalski and Alves (2015). For each sampling point, the penetration, moisture, bulk density, total porosity and particles density of soil at 0.0 -0.10, 0.10 -0.20, and 0.20 -0.30 m depth, and hydraulic conductivity on saturated soil surface were measured.…”

“…Management was adopted in a continuous grazing system, in soil with grazing of Brachiaria decumbens, under rainfed conditions. Three Girolando heifers with an average weight of 300 kg were used, which started the grazing period with a mean forage height of 0.90 m and it was suspended when a mean height of 0.23 m was reached, as indicated by [11].…”

“…Reynolds et al (2002), propôs valores de referência de 0,34 para CAT/PT e 0,66 para CC/PT como parâmetros ideais, indicando que o solo apresenta condições físicas adequadas para crescimento e desenvolvimento das plantas (FIDALSKI et al, 2008). A floresta em restauração apresentou valores de CAT/PT abaixo do limite proposto por Reynolds (2002), sendo 0,23 na camada de 0,1 -0,2 e 0,19 na camada de 0,2 -0,3 m. Esse resultado pode estar relacionado com o histórico de uso e ocupação do solo, em função do pisoteio animal que é considerado um dos principais responsáveis pela degradação dos solos, aumentando a sua densidade, microporosidade e resistência à penetração, consequentemente levando a redução da macroporosidade e porosidade total, principalmente nas camadas superficiais (COLLARES et al, 2011;ALVES, 2015).…”
