Objectives and goals

In recent years, the most serious problem of corn cultivation is the high cost of production, which is also due to the high cost of nitrogen fertilization, which more than doubled, i.e. the cost of urea was 400 euros/ton and in 2022 it reached ~900 euros/ton, creating a huge problem in the cultivation of corn. Thus, in order to improve the income of the producers or to increase the efficiency, the introduction of innovative technologies is considered imperative.

To maximize corn yield, 1/3 of nitrogen (N) fertilization is necessary from flowering to maturity. However, the applied nitrogen fertilization cannot meet the needs mentioned above. In corn, according to the guidelines for rational fertilization, the amount of nitrogen must reach 17 units/acre per 1 ton production in seed. However, the majority of producers apply nitrogen amounts increased by 30-50%.

In addition, conditions are created that favor nitrification, resulting in nitrate ions (NO3-) being washed out. The aim of the proposal is to reduce costs through reduced Fertilization or to increase yields through their better redistribution of Fertilizer, but also to reduce the environmental footprint is the utilization of new technologies and Agriculture. The generated knowledge will be provided to end users (individual farmers, producer groups, cooperatives, rural development consultants) through the appropriate online tools.
