Aspergillus niger and Trichoderma viride strains were used together as a fungal activator in the presence or absence of farmyard manure (FM) for composting of bagasse enriched with rock phosphate. Quality of the composts produced was compared with that obtained from non-inoculated bagasse. The composts were evaluated as organic phosphatic fertilizers, for broad bean plants. The results showed that composting of bagasse without microbial inoculation or FM addition was not complete after 105 days of fermentation. An excellent decomposition in a relatively short time however was obtained with the use of A. niger and T. viride as inoculant agents with or without FM. The inoculation with A. niger + T. viridewith or without FM, also represented the most suitable conditions for phosphate solubilization. Acidic conditions (pH 4–5) at the end of the experiment were obtained in all piles receiving Aspergillus niger and there was a correlation between the amounts of soluble phosphorus and the reduction in pH values in the compost piles. There were no phosphate-dissolving fungi present in any composted piles except those treated with Aspergillus niger and Trichoderma viride. The number of phosphate-dissolving bacteria increased only in the treatments that were treated with FM. The non-fertilized sandy soil and the non-inoculated bagasse compost did not provide broad bean plants with phosphorus while the composts produced by inoculation with A. niger + T. viride provided the plants with the highest amounts of phosphorus.
