TapalovaAbstract The article provides the results of theoretical and applied studies of the use of chelate micro fertilizers for rice cultivation on the saline soils in the Kazakhstani Aral Sea region. The Rez Free enzymatic organic bacterial fertilizers (produced in the USA), an enzyme preparation (produced in Japan), the KN2 domestic preparation and Khelaphos have been used in the experiment. The results of the studies showed the effect of microorganisms on the rice yield. The positive features of the studied Rez Free organic bacterial fertilizer have been identified. The blend with other preparations promoted a yield increase under the given conditions. The developed highly effective methods allow solving the basic problems: soil and water desalinization; increase in humus content in soil and nutrient elements to environmentally safe level; decrease in the supply of toxic substances from the soil to the agricultural cropsÂ’ yield; and increase in the fertilizersÂ’ efficiency to the required level.
