摘要：It is hard today to convince a farmer to move to a new and unknown technology if there are no calculations on return on sales that argue its economic reasoning. In this article, a comparative analysis shall be carried out between the conservative and conventional soil work system at the costs of nutrients (fertilisers) for the most widespread agricultural crops grown in agricultural entities in the country. The use of nutrients in the cultivation process remains a necessity, regardless of the technology applied, and the share of their costs, in the structure of the cost of production, changes according to the technology applied. According to the results obtained, essential changes are found in the structure of unit costs in the crops analysed, depending on the level of nutrients.
