Evaluation of pasture soil productivity in the semi-arid zone of Brazil by microbial analyses

The productivity of a pasture soil (caatinga) located in the region of São João do Cariri, PB, Brazil was evaluated based an the following microbiological parameters: biomass (measured by fumigation-incubation method), activity (estimated from basal respiration and cellulose decomposition rate), qCO...

Descripción
Sumario:The productivity of a pasture soil (caatinga) located in the region of São João do Cariri, PB, Brazil was evaluated based an the following microbiological parameters: biomass (measured by fumigation-incubation method), activity (estimated from basal respiration and cellulose decomposition rate), qCO(2), and C(mic) : C(org) ratio. This analysis demonstrated that livestock management in the ‘caatinga’ is probably causing environment damage by affecting the soil properties, reducing the microbial biomass and soil respiration and increasing the qCO(2), affecting the recovery of this ecosystem.
