Sedimentation of intensive tra-fish bottom ponds is sludge containing toxic elements which they needs to be treated to protect tra-fishs. Using compost from this sludge not only limits environmental pollution but also produces beneficial fertilizer and the aim of this study was constructing a model of combination of sedimentation of intensive tra-fish bottom ponds with plant residues such rice straw, hyacinth, coirdust... with Trichodenna sp. fungus, apatite were incubated in the aerobic-anaerobic bins in the 50 to 56 days, supplementary with beneficial bacteria such as nitrogen-fixing bacteria, phosphate-solubilizing bacteria [at 42 days after incubation] to microbiakompost production. The best model was mixture of 0.2 cubic meter [m3] of sedimentation of intensive tra-fish bottom ponds and 0.4 m3 of many kinds of plant residue plus Trichoderma sp. fungus, apatite (10 kg/m2), beneficial bacteria with pH = 6.21 - 6.97
C total = 15.87 - 18.66 percent
N total = 0.56 - 0.82 percent
C/N ratio = 22.75 - 26.89
available P = 380 - 392 mg P2O5/100 g and population of beneficial bacteria 10 exponent 6 cell/g microbiakompost after 50-56 days incubation.
