MICROBIOLOGICAL PROPERTIES OF MATURE COMPOSTS PRODUCED WITH DIFFERENT ORGANIC MATTER

Abstract

Were studied ten composts originated of different organic matter that were: of tomato (Lycopersium esculentum) (T), soybean (Phaseoulus vulgaris) (F), chickpea (Cicer arietinum) (G), neem (Azadirachta indica) (N), mixture of garden grass (Cynodon dactylon) (P), neem-chickpea (NG), soybean-chickpea (GF), and a mixture of all the previous (vol / vol) (R), vegetable remainders vermicompost (waste market) (LRV) and sugarcane bagasse vermicompost (Saccharum officinarum) (LCC). Were determined the microbiological properties (total amount of bacteria and fungus, and chitin, cellulose and pectine degradators) of mature composts analyzed, as well as the respiration rate measured as C-CO2 of composts microbial biomass. The results shown that the composts varied in their properties depending on the organic matter nature from which they were produced, the amount of microorganisms shown that the composts presented a higher amount of bacteria that fungus, and that there was a higher growth at acid pH that at neutral, besides its effect as soil microflora activators (P and R).
