Agrosilvopastoral systems have been promoted as sustainable models that combine crops,
livestock grazing, and forestry in the same area. We hypothesize that agrosilvopastoral …

Deforestation to establish monocrops in the tropics is causing massive reductions in
ecosystem C stocks. Amazonia is a principal targets of this process, owing to the expansion …

The main cause of physical degradation in pasture areas is overgrazing, and when
combined with poorly productive soils, it causes the loss of millions of hectares of …

The soil carbon under Amazonian forests has an important roles in global changing, making
information on the soil content and depths of these stocks are considerable interest in efforts …

RESUMO A conversão da condição natural do solo para a agricultura, em destaque para a
monocultura de cana-deaçúcar impõe alterações nos atributos do solo. O objetivo do …

Para se avaliar a qualidade do solo e a sustentabilidade em ambientes de Terra Preta

Abstract Changes in carbon (C) and nitrogen (N) reserves reflect the impacts of land use
and management. The objective was to evaluate the changes in organic matter stocks and …

Soils of the tropics are prone to a decrease in quality after conversion from native forest (FO)
to a conventional tillage system (CT). However, the adoption of no-tillage (NT) and complex …

The objective was, therefore, to evaluate the impact on organic carbon and the formation of
soil aggregates in areas of natural vegetation converted into pastures in southern …
