Potato cultivation is mainly influenced by the type of fertilisers used, the dosage of mineral or organic fertilisers applied based on the soil nutrient supply and texture of the soil. The potato’s particularities in growing stolons and tubers in the soil, the superficial root system, reltively smaller when compared to the above-ground part, make the plant’s soil condition requirements different from other crops. The purpose of these experiments was to determine the nutrient content in the soil, in order to accurately determine the macro- and micro-element requirements, decided before starting the cultivation, as they are highly important in order to obtain a good yield. In order to monitor the soil nutrient supply, soil samples were taken at a depth of 0-20 and 20-40 cm for ten different varieties, i.e. Arizona, Esmee, Riviera, Red Lady, Carrera, Jelly, Red Fantasy, Levantina, Bellarosa and Luna Rosa, and based on them the ph values, the humus, nitrogen, phosphorus, potassium and mobile form (Cu, Fe, Mn, Zn) content were established. Soil analysis is extremely important before starting the cultivation, because it helps farmers determine whether the type of soil is suitable for the plants to be grown and to determine an adequate fertilisation plan.
