Distribution of phosphate solubilizer fungi on soil microhabitats in two landscapes from Guaviare, Colombia

Abstract

The distribution of the phosphate solubilizer mycobiota in two different soil microhabitats present in Guaviare, Colombia, were studied. Twelve samples from Arazá rhizosphere (Eugenia stipitata McVaugh) and from soil without roots were processed using the soil wahing method (Domsch et al., 1980). The percentage of colonization of soil particles by fungi was 69 %, with a higher intensity of colonization coming from the rhizospheric microhabitat. The high percentage of potential solubilizer colonies may point to this type of soil as reserve pf solubilizer fungi. The rhizospheric effect has been the main factor involved in the composition of the solubilizer fungi community.
