Physical properties of an Oxisol under different planting and management systems

摘要: The changes of soil physical and mechanical properties, arising from the traffic machines in farming operations, have been widely studied, emphasizing negative effects compaction on crop productivity. objective was to evaluate properties an Oxisol under different planting management systems. A completely randomized design one-way adopted for collection samples. treatments consisted four systems (no tillage, conventional planting, area pasture fruit cultivation) with three replications. All samples were obtained at a depth 0 0.15 m. were: bulk density, degree compaction, liquid limit, plastic limit total porosity. varied statistically (P<0.05) management. cultivation has demonstrated all attributes good quality, since over years accumulation organic matter decomposition leaves may caused this better quality soil. are more susceptible erosion, principally first case where disaggregation by system can enhance erosion As conclusion, density shown that no tillage worst soils’ properties. Key words: Compaction, limits consistency,
