Relationship Between The Diversity of Mycorrhizal Arbuscule Fungi with The Physic-Chemical of Dystropept Soil

Abstract

The one of poor soil in West Kalimantan is the dystropept soil which includes sub ordo of inceptisol. This soil spread sporadic and relatively much in the production forest areal. Increasing the dystropept soil quality through the microbial approach is very rare or even may not have been done. As a first step, the purpose of the research was to determine the abundance and diversity of AMF (arbuscular mycorrhizal fungi) and the relationship of dystropepts soil characteristic with AMF diversity. The method consisted of taking soil samples at the location in depth of 0-20 cm, 20-40 cm and 40-60 cm, and location II in depth of 0-20 cm; identifying spore-based on morphology. Analyzing data used the pattern of relative abundance, diversity index, evenness index, and biplot RDA. The results were Glomus was dominant genera with high abundance and low species diversity in all location and uneven distribution of species. This diversity of species positively with excellent sand content, Mg, CEC, N, BS, K, and C.
