Morphostructural characterization of soil conventionally tilled with mechanized and animal traction with and without cover crop
01/Dec/2010
The structural stability and restructuring ability of a soil are related to the methods of crop management and soil preparation. A recommended strategy to reduce the effects of soil preparation is to use crop rotation and cover crops that help conserve and restore the soil structure. The aim of this study was to evaluate and quantify the homogeneous morphological units in soil under conventional mechanized tillage and animal traction, as well as to assess the effect on the soil structure […]
Morfological and physical transformation in a clayey oxisol under pastures
01/Dec/2001
This study was carried out in the Western region of Minas Gerais, Brazil to evaluate the morphological changes in a Yellow-Red Latosol, after a conversion of a 20 year old Brachiaria decumbens pasture, under intensive pasture systems; a pure Brachiaria decumbens and an association of this grass with the legume Stylosanthes guianensis. Through morphological and physical characterization, it could be concluded that: (a) there were structural obstructions to radicular development in the old pasture soil; (b) the soil macrofauna played […]
