Microbial biomass carbon and mycorrhiza in soil under native wood and coffee (Coffea arabica) agroecosystems. The microbiological properties of dystrophic red Latosol under coffee trees in systems of organic, in conversion and conventional production were studied related to a patch of native wood on two neighbouring farms situated in the town of Santo Antonio do Amparo, Minas Gerais, Brazil. The farming presents the same cultivar (Acaia IAC-474-19) and age (five years). The microbiological sampling of the soil was accomplished in dry (July 1999) and rainy (December 1999) periods. Microbial biomass carbon presented greater values in the rainy season in all systems. No differences were recorded for the mycorrhizal colonization. In relation to the identified species of arbuscular mycorrhizal fungi, the frequency of occurrence was greater for the genera Acaulospora, Glomus and Gigaspora, in all treatments. |
