In economic examination of the precision farming technology we must attend to the extra cost of applying this technology, the value of the available saving and not least the investment cost of this technology variant. In this paper the precision farming technology was examined from economic aspect. The research was made on a case of model-farm. In the model-calculation applying precision farming technology means decrease of sprayed-out chemical amount and material cost, which due to site-specific spraying (which makes increase in operational cost). The main aim of the model is to determine the extra income of precision farming technology.
