The no-till system with complex cropping sequences may improve the structural quality and carbon (C) sequestration in soils of the tropics. Thus, the objective of this study was to evaluate the effects of cropping sequences after eight years under the no-till system on the physical properties and C sequestration in an Oxisol in the municipality of Jaboticabal, Sao Paulo, Brazil. A randomized split-block design with three replications was used. The treatments were combinations of three summer cropping sequences – corn/corn […]

The maintenance and improvement of soil quality are crucial to the stability, sustainability and productivity of natural ecosystems and agroecosystems. The understanding and quantification of the impact of tillage systems in their physical quality are fundamental in the development of sustainable agricultural systems. This study was carried out to evaluate the effects of management practices on physical properties and organic matter content of an Ultisol cultivated with cassava following the use of distinct cover crops. A field experiment was carried […]

Some of the pedologic alterations resulting from traditional soil management methods were studied in an area cultivated with citrus (Citrus sinensis) in a farm in Bariri County, State of São Paulo, Brazil. A toposequence was established to evaluate the effect of the position in the landscape on changes in soil physical attributes. Field and lab data were taken in vertical profiles of the upper, middle and lower slope levels of a Typic Haplorthox and some parameters were evaluated statistically through […]
