This paper presents the research results of treatment solution of wood waste of Acacia and Eucalyptus in making of bioorganic fertilizers for aim of effective utilization of plant biomass resources and minimize environmental pollution. Has established some aspects of conversion of the wood waste basic chemical compounds in compo sting process by two biological products biomix and compost maker has been established. Research results have shown that, under the action of microorganisms, all of the basic chemical compounds are modified, as the most powerful modified cellulose, lignin, extractives dissolved in ethanol and other compounds less was destructived. Within about first 75 days of composting, the conversion of the above mentioned compounds is negligible. With composting time from 105 days to 120 days, in total over of 70 percent of cellulose was conversed into compounds dissolved in water and 1 percent sodium solution. The optimal composting time was about 105 days. In this case, the fertilizer has been humus, had dark colors and can be used for planting and soil improvement purpose.
