ABSTRACT Cultivated soils, when submitted to agricultural practices, tend to compact due to the pressure exerted by agricultural machines and implements, a process that compromises soil quality and system sustainability. Specific properties of each soil, such as particle size and organic matter content, interfere with the process and degree of compaction and, consequently, plant growth. This study aimed to analyze the effect of different degrees of compaction (DC) on soil physical properties and black oat (Avena strigosa Schreb) growth. For […]

The compaction of agricultural soils is a phenomenon of great concern in Soil Science. The major goal of research on the mechanical behavior of soil is to identify the least degrading soil management systems. In general, at a same compaction level, the higher content of organic matter, the lower maximum density and higher critical moisture for compaction, which consequently decreases the risk of physical degradation of the soil. The purpose of this study was to study the compressibility of a […]

Understanding and quantifying the impact of land use and soil management on soil organic carbon (SOC) levels and physical properties is essential for the development of a sustainable agriculture. The purpose of this study was to evaluate some physical properties and SOC of an Oxisol in the Northwest of the state of Paraná, under different use and soil management systems, i.e., under native forest, pasture, cassava, and sugarcane. Disturbed soil samples were collected for particle size, particle density, proctor and […]
