This paper aims to evaluate the effects of nitrogen and phosphorus mineral fertilization, applied in varying doses, on the quality of maize crops grown in acidic soils. The study is based on a long-term bifactorial experimental design, involving progressively increasing doses of nitrogen and phosphorus (arranged in a 5P × 5N scheme, with N0-N160 combined with P_O, P₄₀, P₈₀, P₁₂₀, and P₁₆₀), alongside lime application. The findings offer valuable insights into the long-term impacts of these fertilization practices on crop quality. Results show that long-term fertilization combined with calcic amendments induces statistically significant changes in the macroelements content of maize leaves specifically nitrogen, phosphorus, potassium, calcium, and magnesium and the microelements content, including copper, zinc, manganese, and iron.
