This investigation could isolate phosphate solubilizazing microorganisms identified as
Enterobacter agglomerans that may contribute to increase this element availability at the
soil of Denmar S.A. The microorganism’s solubilization efficiency was determined “in
vitro” by analysis of atomic absorption spectroscopy (AAS), using three different
concentrations of phosphorus C1 = 0.03 [M]; C2 = 0.05 [M]; C3 = 0.07 [M] in a modified
liquid Pikovskaya culture medium. For field evaluation the identified bacteria was used
to develope a biofertilizer which was inoculated into a compost to be incorporated into the
soil of both farms. Finally, soil samples through physical and chemical analysis showed
changes improving the content of micro and macronutrients, mainly the reduction of
phosphorus in Marledian of 294.0 ppm to 298.0 ppm and 23.9 ppm to a 20.9 ppm in
Astroflores. |
