The study presents the results of a 4-year field study aimed at assessing the nutrition of maize plants in relation to the depth of two-component (NP) mineral fertilizer placement in the soil layer (0, 5, 10, 15 cm), the type of nitrogen fertilizer (ammonium nitrate, urea) and the date of its application (before sowing, BBCH 15/16). It was demonstrated that the ini-tial phosphorus application elevated nitrogen content in the ear leaf with the increase in mineral fertilizer placing depth in soil, while zinc to the depth of 5 cm. DRIS analysis confirmed the significant impact of the depth of phosphorus fertili-zer placement on the plants’ nitrogen balance. Initial fertilization with phosphorus improved the plant nutritional status, indicating N as the main deficient nutrient at the BBCH 63 stage.
