Based on the plant-nutrient soil capacity and the supply of lemon trees with biogenic elements, we will determine if there are visible differences in the lemon orchard due to specific soil and mineral nutrition physiology differences. Furthermore, the determined concentrations of biogenic elements (macro and microelements) in the plant material, specifically lemon leaf (Citrus meyeri), will be compared with reference values for lemon, to assess the degree of lemon nutrient supply with these elements. The results of chemical analysis of plant material and the supply of biogenic elements indicate lower nitrogen values in the plant material - lemon leaf, which is the main reason for the visible chlorosis of the leaves. Additionally, all three primary macronutrients (N, P, K) in both samples of plant material were lower than the recommended values for plant material, especially N and Ca in the leaves on the "lt" side. However, magnesium (Mg) values were optimal in both analyzed samples. Among the analyzed micronutrients, we emphasize the elevated boron (B) levels and lower copper (Cu) and zinc (Zn) levels. These findings should be considered in the future, considering possible inputs (pesticides, foliar fertilizers). We particularly emphasize the need to create favorable conditions for nutrient uptake through optimal irrigation during the vegetation period because despite the rich potassium supply in the soil and good supplies of phosphorus and total nitrogen, we do not have a good supply of plants with these nutrients. Additionally, nitrogen fertilization should be applied multiple times during the vegetation period, preferably in conjunction with lemon orchard irrigation.
