Abstract

Potassium replenishment, particularly in smallholder agriculture, remains a challenge as it is mainly fertilizer dependent. While the user of soluble mineral potassium fertilizers is the obvious best means to combat potassium deficiency in soil, they were limited by high cost of fertilizers and availability at farmer’s level. This research is to isolate and select potassium solubilising soil fungi from ceramic industry soils. 4 fungi isolates were inoculated on Aleksandrov agar supplemented with 0.5% potassium aluminium silicate, isolates which gave the high ratio of clear zone were selected. Two fungal strains out of 4 strains, i.e., KF1 and KF2 which solubilized potassium aluminium silicate and showed the highest available potassium in liquid medium. One of the fungal strains is fast growing black colonies on potato dextrose agar with distinctive conidial heads characterized as Aspergillus niger. While another shows green powdery colonies on potato dextrose agar and characterized as Aspergillus terreus. KF 1 shows highest potassium solubilisation and acid production by utilizing feldspar and potassium aluminium silicate as an insoluble source of potassium.
