The compaction caused by anthropic activities alters the soil physical properties, decreasing productivity and affecting the environment. Many studies on this topic have been conducted in agricultural soils; however there is little information in areas with native vegetation, where, usually, organic matter levels are higher. Thus, it is essential to evaluate the relationship between physical properties related to compaction under these conditions to establish reference values for the revegetation of native grassland or riparian forests. The objective was to relate […]

Macroporosity is often used in the determination of soil compaction. Reduced macroporosity can lead to poor drainage, low root aeration and soil degradation. The aim of this study was to develop and test different models to estimate macro and microporosity efficiently, using multiple regression. Ten soils were selected within a large range of textures: sand (Sa) 0.07-0.84; silt 0.03-0.24; clay 0.13-0.78 kg kg-1 and subjected to three compaction levels (three bulk densities, BD). Two models with similar accuracy were selected, […]
