Abstract: Organic wastes are useful in agriculture as organic and nutrients fertilizers. Changes in soil environment after application of organic wastes may be successfully controlled using conventional and molecular methods. Microorganisms play important role in soil organic matter transformations. Evaluation of their enzymatic activity, functional and genetic diversity can be used as sensitive tool to asses soil quality and fertility. It is important to combine conventional microbiological methods with molecular techniques, to obtain more information about population of soil microbiota.
