The results of three years of polyfactor field experiments, in which we monitored and evaluated the economics of nutrition and fertilisation of corn, indicate the following conclusions: Economic effectiveness of fertilisation was conditioned by the year. This is corroborated by a positive interactive influence of fertilisation variants and year on the crop of corn. This influence can be statistically proven. The three year results confirmed an economically significant influence of a leaf fertiliser in combination with solid fertilisers. At the A level fertilisation we reached the highest crop by using the Humix universal leaf fertiliser in two years out of three. At the B and C levels of fertilisation the fertiliser Wuxal kombi Mg was more effective. From the economical point of view the B3 level of fertilisation appeared to be optimal. At this level the average coefficient Eef during the three monitored years was 1.11 with the profit of 550.2 Sk per ha, i. e. 18.3 € per ha.
