SPATIAL VARIABILITY OF SOIL PHYSICAL ATTRIBUTES UNDER MECHANICAL HARVESTING OF BUFFEL GRASS IN PERNAMBUCO'S AGRESTE Engenharia na Agricultura
Dias Batista, Pedro Henrique; Almeida, Gledson Luiz Pontes de; Tavares, Uilka Elisa; Nascimento, Vitor Nepomuceno do; Sarmento, Roger Moura.
Studies on soil physical quality have evolved significantly over the last few years, mainly in cultivated areas and under pastures. The objective of this study was to evaluate the spatial dependence of soil physical attributes in a dystrophic Regolithic Neosol. The study was conducted at the Roçadinho Farm located in the municipality of Capoeiras, located in the Microregion of Ipojuca Valley, Agreste Mesorregião of the State. The study area is formed by pasture of Búffel grass (Cenchrus ciliares L.) over 6 years old, mechanically harvested. In order to determine the physical attributes of the soil, 3 soil layers (0.00-0.10, 0.10-0.20 and 0.20-0.30 m) were investigated, the hydraulic conductivity of the soil was determined by the method Of Beerkan, in 36...
