In this research Trichoderma harzianum was used as inoculated in composting, the inoculants was termed compost activator. Mixing Trichoderma harzianum as bioactivator with substrates (sugarcane bagasse) reduced composting period from 180 days to 60 days, also effect of inoculation of this fungi on solubilization rock phosphate and increase amount of phosphorus was assessed. Inoculation of fungi increased contents of p in during of composting. Application of sulfur to treatments that inoculated with Trichoderma harzianum fungi, causes increases quantities of sulfate as well as total fungi populations and electrical conductivity but lower pH and total bacteria numbers. Therefore, sugarcane bagasse mixed with phosphate solubilizing fungi will produce a phosphorus and sulfate rich compost (in case rock phosphate and sulfur are also used) in the shortest time worthy of distribution to serve not only as an organic fertilizer but also as an inoculants as well as can use as bioactivator and controlling agent for fungi diseases. Keywords: Trichoderma harzianum, Rate of decomposition and Compost enrichment.
