Resumo: The objective of this work was to evaluate the spore density and diversity of arbuscular mycorrhizal fungi (AMF) in soil aggregates from fields of “murundus” (large mounds of soil) in areas converted and not converted to agriculture. The experiment was conducted in a completely randomized design with five replicates, in a 5x3 factorial arrangement: five areas and three aggregate classes (macro‑, meso‑, and microaggregates). The evaluated variables were: spore density and diversity of AMF, total glomalin, total organic carbon (TOC), total extraradical mycelium (TEM), and geometric mean diameter (GMD) of soil aggregates. A total of 21 AMF species was identified. Spore density varied from 29 to 606 spores per 50 mL of soil and was higher in microaggregates and in the area with 6 years of conversion to agriculture. Total glomalin was higher between murundus in all studied aggregate classes. The area with 6 years showed lower concentration of TOC in macroaggregates (8.6 g kg‑1) and in microaggregates (10.1 g kg‑1). TEM was greater at the top of the murundus in all aggregate classes. GMD increased with the conversion time to agriculture. The density and diversity of arbuscular mycorrhizal spores change with the conversion of fields of murundus into agriculture.

O experimento foi conduzido em delineamento inteiramente casualizado com cinco repetições, em arranjo fatorial 5x3: cinco áreas e três classes de agregados (macro, meso e microagregados). As variáveis avaliadas foram: densidade e diversidade de esporos de FMA, glomalina total, carbono orgânico total (COT), micélio extrarradicular total (MET) e diâmetro médio geométrico (DMG) dos agregados do solo. Foram identificadas 21 espécies de FMA. A densidade de esporos variou de 29 a 606 por 50 mL de solo e foi maior nos microagregados e na área com 6 anos de conversão para agricultura. A glomalina total foi maior entre os murundus em todas as classes de agregados em estudo. A área com 6 anos apresentou menor concentração de COT nos macroagregados (8,6 g kg‑1) e nos microagregados (10,1 g kg‑1). O MET foi maior no topo dos murundus em todas as classes de agregados. O DMG aumentou com o tempo de conversão para agricultura. A densidade e a diversidade de esporos de fungos micorrízicos arbusculares mudam com a conversão dos campos de murrundus em agricultura.Embrapa Informação Tecnológica2015-12-07T12:29:06Z2015-12-07T12:29:06Z2015-04-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfCARNEIRO, M.
