SELECTION OF STRAINS NODULE BACTERIA TO RECULTIVATION SOIL SALINITY, SOIL DRILL CUTTINGS

For increasing crop yields worldwide, along with mineral fertilizers big role to use bacterial fertilizers. Low cost, high return, safe for the environment, determines their widespread use. However, for the successful use of bacterial fertilizers need to know their interaction with soil, drill cuttings, soil, plants and fertilizer inputs. It is important to know that the microorganisms comprising the active principle of bacterial fertilizers require for their development of certain conditions (humidity, temperature, nutrient availability, etc.). The paper presents the results of laboratory model studies to identify the most salt-tolerant strains of rhizobia to inoculate legume seed-phitomeliorant used for reclamation of drill cuttings, saline soils and soils. Experiments were conducted at extremely saline nutrient media with one or more salts. Studies have shown that the highest salt tolerance in nutrient mixtures possessed colonies nodule bacteria under the number 282 (for melilot) and 423b (alfalfa). On the drill cuttings to maximize symbiotic nitrogen fixation are not matched active virulent strains of nodule bacteria of melilot and alfalfa, not the technique of initial inspection (testing) different strains of rhizobia. Address these and other issues devoted to this work. It reflects elements of the new direction of soil microbiology — soil biotechnology. Their mission is to study and regulation of soil microorganisms and microbiological processes in order to optimize conditions for plant growth and development.
