BELTRAN PINEDA, M. E. Phosphate Solubilizing Fungi in Paramo Soil Cultivated with Potato (Solanum tuberosum). Ciencia en Desarrollo [online]. 2014, vol.5, n.2, pp.145-154. ISSN 0121-7488.

The Phosphate Solubilizing Fungi (PSF) is a functional group of microorganisms that play a fundamental role in the cycling of phosphorus in soils; due to its activity, plants can take advantage of the large reserves of insoluble phosphorus that is attached to mineral soil, contributing to the decrease of the application of phosphorus fertilizers. In this study we were able to isolate 43 fungal strains with phosphate solubilizing capacity from the rhizosphere of potato crops (Solanum tuberosum) set in the paramo of Rabanal. After the process of qualitative and quantitative assessment of the phosphate solubilizing capacity of two fungal isolated potential biofertilizer strains, belonging to the genera Scopuraliopsis sp. and Penicillium sp. were obtained, that could be the basis for the formulation of biofertilizers. The application of these inputs in soils, constitutes a strategy for sustainable fertilization, contributing to the alleviation of contamination in strategic areas as the paramo.
