The objective of this work was to assess the effects of integrated crop-livestock systems, associated
with two tillage and two fertilization regimes, on the abundance and diversity of the soil macrofauna. Four
different management systems were studied: continuous pasture (mixed grass); continuous crop; two croplivestock
rotations (crop/pasture and pasture/crop); and native Cerrado as a control. Macrofauna was sampled
using a modified Tropical Soil Biology and Fertility method, and all individuals were counted and identified at

Soil microbial biomass is considered as an important early indicator of changes that may occur
in the long term with regard to soil fertility and constitutes an important source and sink of nutrients. In
South Africa, rangeland monitoring has mostly focused on assessing changes of aboveground vegetation
in response to land uses effects, but the associated changes at belowground soil level remain a topic of
further research. The aim of this study was to explore soil microbial biomass at three sites under

Soil organic carbon stocks in semi-arid West African drylands: implications for climate change adaptation and mitigation

In the West African drylands, SOC sequestration is seen as one of the prominent strategies to both enhance the resilience of agro-ecosystems and mitigate global greenhouse effects. However, there is a dearth of baseline data that impede the design of site-appropriate recommended management practices (RMPs) to improve and sustain SOC accrual.
