ECOLOGICAL ASPECTS OF THE USE OF HERBICIDES IN SOWS OF CORN

Development of resource-saving technologies of cultivation of crops is one of the major challenges in today's global economy at the moment. First of all this can be achieved by replacing a number of energy-intensive operations such as the inter-row treatments of herbicides. This significantly reduces the cost of crop production. When uncontrolled use of pesticides may contaminate the soil metabolic products of plant protection products on the weeds. Environmental aspects of the problem are not well understood. The author studied the effect of regular use of herbicides on biological-based communities аctivity properties of black leached soil of the Republic of Mor- dovia in the maize. The use of herbicides helped reduce the cellulolytic activity of soil. Also decreased intensity soil release carbon dioxide, indicating a negative influence on the microbiological properties of the herbicide black leached soil. It should be noted that the use of systemic herbicides helped increase maize yields
