Abstract - The objective of this work was to test the potassium (K) solubilization from minerals of an alkaline ultramafic rock powder by two strains (CCT4355 and CCT911) of Aspergillus niger. The experiment was carried out in triplicate in 250 mL erlenmeyer flasks over a period of 35 days. Soluble K, titratable acidity and pH were analysed and the solubilization rate (SR) was calculated relative to the total K in the rock powder (2.921 mmolc/L).The data obtained showed that both strains of A. niger fungus have high potential of K solubilization and could be used as an alternative for small farmers to produce biofertilizers using rock powder. |
