Fine-texture soils in Brazil are generally deemed to have low agricultural potential. Due to low levels of clay and organic matter, they usually present low nutrient and water retention capacity, and, when poorly managed, may produce negative impacts associated with high risks of groundwater contamination by nutrients and other chemical pollutants, or with potential erosion when directly exposed to rain.

In order to guarantee agricultural sustainability in environments associated with t ...

Soil quality may be measured through the use of indicators, which are attributes that measure or reflect the environmental state or condition of sustainability of the referred ecosystem. The knowledge regarding the spatial distribution of soil quality and its levels becomes essential in this case, once it favors the study of their relation with the type of soil management, with the environmental impact and the productive capability of agricultural systems. For such, it is important to have a met

Pasture degradation is one of the main problems of Brazilian cattle farming. Several strategies to recover the productivity of degraded pastures have been developed by Embrapa and other research and education institutions. In such studies, reducing the costs of the recovery of degraded pastures has been one of their main focuses. Integrated crop-livestock systems (ICLS) have proved to be some of the best alternatives to reduce the costs of pasture fertilization. ICLS have potential to increase t
