In the conditions of the Republic of Belarus there were considered some aspects of modern and prospective mineral fertilizers application in precise agriculture systems. Economic use of chemicals in agricultural farming is the basis for improving crop performance and, as a consequence, livestock sectors that provide the ultimate substantial increase in the production of higher quality and cheaper food for the population and for export. Thus, technology and mechanization of differentiated fertilizing remain the prerogative of engineering, agrochemical and other sciences. Their task should include the development of scientific basis for use of this method of fertilizer application (development of scientific and methodological aspects of evaluation of the limits of effective differentiated application of fertilizers, substantiation of quality indexes of the technological process, development of methods of evaluating options of the rational differentiated application, etc.) and determination of the actual economic effect from the introduction of the mentioned technologies and mechanization in the conditions of the republic. And at the present time the urgent and priority task should be the implementation of the concept of a uniform and timely (in optimal agronomic terms) fertilizer application, taking into the account that there is a direct correlation between the yield increase and crop fertilizing with its uneven application. In other words, the smaller the unevenness is, the higher increase in yield of the first introduction of nitrogen fertilizers and vice versa.
