Abstract

LOSS, Arcângelo et al. Chemical attributes of soil and occurrence of mycorrhizal fungi under areas of pasture and agroforest system, Brazil.. Acta Agron. [online]. 2009, vol.58, n.2, pp.91-95. ISSN 0120-2812.

This study had as objective characterize the chemical attributes of soil and to evaluate the community of arbuscular mycorrhizal fungi (AMFs) in a pasture area and agroforest system (AFS). The area this study is located in the Agroecological Farm, 22° 45'S, 43° 41'W, in the Seropédica, Rio de Janeiro State, Brazil. The soil samples were taken in depth of 0-5 cm and quantified the tenors of total organic carbon (TOC), Ca, Mg, pH, P and K. They were counted and identified the spores of FMAs. The found results were analyzed as design entirely casuality, with application of the test F. Verified statistically higher values of COT, Ca, Mg and K in AFS, as well as the largest number of spores of mycorrhizal fungi. One was observed lowers diversity of species of FMAs, and Glomus macrocarpum and Acaulospora scrobiculata were the dominant species in the two areas. The management of the soil might have influenced in the smallest number of spores of FMAs found under pasture. Through the analysis of main components it was possible to separate the two appraised areas, being the behavior similar to the verified in the univariate analysis.

Keywords : Nutrient acquisition; infectivity potential; microbial ecology; mycorrhizal colonization.
