 ABSTRACT

The main objective of this paper is to promote the use of organic acids applied in enriched organic amendments and inoculated seeds for agricultural improve volcanic Ecuadorian soils. The physical, chemical and biological properties of soils derived from volcanic ash are strongly influenced by the degree of weathering of the pyroclastic materials, the Ecuadorian andisols are soils derived from volcanic ash materials, which unique characteristic is the presence of amorphous and easily weathered silicate minerals. The presence of the indigenous microorganisms in the soil such as Pseudomonas spp., Rhizobium spp., Burkholderia spp., Achromobacter spp., Agrobacterium spp., Aereobacter spp., Flavobacterium spp., Yarowia spp., Streptosporangium spp. and Erwinia spp. plays an important role on the rate not only of carbon and nitrogen stabilization but also of mineral stabilization, since they have the capacity to produce low molecular weight organic acids; which end up forming stable humified materials in andisols.

Keywords: Amorphous Materials, Weathering, Mineral Stabilization, Carbon Stabilization, Nitrogen Stabilization
