Description:	The objective of this study was to evaluate the microbial activity of carbon, nitrogen and phosphorus resulting from the replacement of the primary forest with Brachiaria brizantha, Hevea, cupuaçu, citrus and secondary forest. There was no increase in soil fertility under secondary forest, but in the pasture had an increase in the stock of C and N and high C/N ratios, the inverse occurred with C-microbial biomass. The primary forest had the highest values of C, N and P of the microbial biomass and the lowest metabolic quotient. The Hevea was the plant cover with the smallest changes of C in the soil.
