The objective of the present study was to transform the waste generated by local cotton agribusinesses, grain crushing, and chicken eggs producing farms, in agricultural inputs with high added value, with feasibility to improve the chemical, physical and biological soil. We studied four combinations of waste from the five most abundant in agro-industrial by-products around the city, having as nitrogen source (N) chicken manure (EG), and as sources of carbon (C): burs, sticks, fiver trash (CA), cotton motes seed (LA), as well as carbon from ovens (CF), earth filter (TF), and residuals from the oil purification plant. In order to accelerate the mineralization process of SOM during composting, three biocatalysts were applied to each treatment, each of them with different action behavior (B1, B2, B3). Furthermore the temperature of each window was systematically monitored in degrees Celsius (° C). Also, pH, moisture (%) and volume (m3) were monitored. The 16 treatments were arranged in three replications on experimental design randomized block. The obtained data base was analyzed in terms of variance and multiple comparisons of means by Tukey at 5% significance. The biocatalysts tested had significant influence increases OM and nutrients contained in different composted byproducts combinations. The biocatalyst B3 applied to EG-CA combination, when applied more frequently to such combination resulted in increased quantity of nutrients for the composting. The applied quantities of biocatalysts, under different residues combinations, showed significant influence on the temperature (° C), and the pH. However, no significant changes in volume (m3) and the granulometry of the waste composted were observed.
