The cultivation of potatoes is mainly influenced by the type of fertiliser used, the dose of mineral or organic fertiliser applied based on the soil’s supply of nutritional elements and the structure of the soil. The goal of these fertilisation experiments carried out in 2020 was the calculation of optimal and economical doses of NPK fertilisers, based on the soil’s supply of nutritional elements, in order to obtain consistent yields of a certain level, using the methodology of an agrochemical study, and to determine the influence of various doses of fertilisers on the yield and on the production efficiency in potato cultivation. To monitor the soil’s supply, agrochemical mappings were carried out, used to determine the optimal economical doses required to obtain a yield of 50 t/ha for three potato cultivars: Riviera, Bellarosa ans Arizona. Comparisons were made based on the data obtained, between the doses used by the company Solfarm SRL and the optimal N, P, K fertiliser doses necessary for a yield of 50 t/ha.
