Abstract: The article is dealing with the relation of the soil value and nitrogen needs as the major intensification factor jointly affecting the quality of the environment. According to the obtained data and knowledge from about 500 surveyed plots, the premises of production function proposals are analyzed with regard on their further use in optimization of economics of crop production and their impact on soil value. Based on values of production functions and in compliance with field experiment results, done a sophisticated computation of an optimal nitrogen dosage amount is adjusted according to farm gate price of wheat and purchase price of nitrogen with respect to environmental requirements on the production. Results are compared with the application of nitrogen and yields achieved in agricultural practice.
