Resumo
Current studies show a decline in soil biodiversity, which puts at risk future food production since soil organisms\nplay a key role in essential ecosystem functions such as, nutrient cycling and soil fertility, soil carbon sequestration,\nclimate regulation, litter decomposition, erosion, water retention, interaction with plants, among others. This study\naims to evaluate how the conversion of a tropical native forest into a field for agricultural production impacts the soil\nphysical-chemical parameters and how these correlates with the abundance of specific group of microorganisms. The\nsoils analyzed were collected in Guinea-Bissau, at 3 locations with different land uses: a primary forest, an annual crop\nfield (peanut) and a perennial crop field (cashew), during the wet and dry season. We analyzed several soil parameters\nincluding pH, water content, N, P and C contents, soil respiration, and soil protein index. Mycorrhizal spore density,\nanalysis of soil PLFA (Phospholipid fatty acids), and qPCR targeting genes involved in N, C and P cycling, were selected\nfor investigating changes in soil microbial diversity. Our results confirm that land use changes alter soil physically and\nchemically, and its microbial community as well
