ABSTRACT



The paper presents a new method of optimization of the choice of agricultural machines, which consists in determining the conditions that should be fulfilled in order that the purchase of a machine will be profitable for a farm. The method means making use of functional relations describing the dependence of unit costs of exploitation of an aggregate for organic fertilization with liquid fertilizers on the efficiency and the yearly time of the use of an aggregate. The results were analyzed in three aspects. The first referred to the profitability of the purchase of a machine for one’s individual use. The second concerned the profitability of rendering the services, while the third – determining the conditions in which it will be profitable to use the purchased machine or device.

Key words: method, choice, ascenization fertilizers, optimization.
