Conservation tillage systems in orange groves can increase soil load-bearing capacity minimizing their risks of soil compaction. The objective of this study was to evaluate load-bearing capacity through preconsolidation pressure and its dependence on water content, bulk density, and organic carbon of a Typic Paleudult soil 18 years after setting up permanent plant cover between the rows of an orange grove. A randomized block experimental design was used, with three replications. Three groundcover treatments subjected to mowing between the rows […]

The construction of a soil after surface coal mining involves heavy machinery traffic during the topographic regeneration of the area, resulting in compaction of the relocated soil layers. This leads to problems with water infiltration and redistribution along the new profile, causing water erosion and consequently hampering the revegetation of the reconstructed soil. The planting of species useful in the process of soil decompaction is a promising strategy for the recovery of the soil structural quality. This study investigated the […]

The use of cover crops has been suggested as an effective method to maintain and/or increase the organic matter content, while maintaining and/or enhancing the soil physical, chemical and biological properties. The fertility of Cerrado soils is low and, consequently, phosphorus levels as well. Phosphorus is required at every metabolic stage of the plant, as it plays a role in the processes of protein and energy synthesis and influences the photosynthetic process. This study evaluated the influence of cover crops […]
