The system of no-till sowing stands out as being a technology that suits the objectives of more rational use of the soil and greater protection against the erosion. However, through till, any of it, occurs modifications of the soil’s structure. This current work aims to study the influence of the energy state of the water and of the organic matter on the mechanism of compaction of Red Oxisol under no-till management system. Humid and non-deformed sample were collected in horizon […]

The agricultural use of soils usually relies on the use of heavy machinery that cause soil compaction, affecting the amount of air and water available for plants. The present study was carried out in the year 2000 and aimed at studying the performance of aggregates of an Amazon Oxisol under mechanical compression and that were subjected to varying degrees of matric potential. Humid and undisturbed tropical forest soil samples were collected from the A horizon (10 cm deep) and B horizon […]
