The restraining economic situation that lasts for a number of years has led to sharp cutbacks of mineral fertilization in plant production. The consequence of this practice was a reduction of natural fertility of our soils. With the ultimate objective of soil protection, soil fertility status and contamination were analyzed at the Rimski Sancevi experiment field of the Institute of Field and Vegetable Crops. To establish the current situation, 189 samples were taken from 42 soil profiles for complete soil fertility analyses. To be able to handle such a large volume of analytical data, a software program has been developed for the analytic, statistic and graphic processing and presentation of the results. The results were used for the calculation of cost-efficient doses of fertilizers needed to obtain maximum yields of the crops grown, simultaneously keeping in mind the economy and profitability of production and the maintenance and protection of soil and the agroecosystem on the whole.
