RIEPT Trials - Ecosystems H: Isohyperthennic savannas por International Center for Tropical Agriculture

“…In the first, known as Regional Trials C (RTCs), the idea was to incorporate new germplasm in pastures to study its potential compatibility under grazing in small plots in terms of productivity (dry-matter yields and carrying capacity) and persistence (dynamics of botanical composition, changes in plant architecture, and seed reserves) under different grazing management systems. …”

Diversity of arbuscular mycorrhizal fungi in the Brazilian's Cerrado and in soybean under conservation and conventional tillage por Pontes, J.S., Oehl, F., Pereira, C.D., Machado, C.T., Coyne, Danny L., Silva, D.K. da, Maia, L.C.

“…In conclusion, soil cultivation and fertilizer application lead to decreased AMF species richness but remarkably AMF diversity was maintained on similarly high levels in soybean-based crop production systems, even under intensive soybean mono-cropping. The changes in AMF community structure rather were linked to soil pH and potassium, calcium and magnesium than to phosphorus availability or the organic carbon contents. …”
