The necessity of chemical use reduction in agriculture is frequently mentioned. Due to the technical development of chemical and machine industries, we have solutions to spread fewer ingredients per hectare than we did 30 years ago. One of these techniques is site-specific crop production. Depending on the number of farms and land used by turning to site-specific pesticide use, the savings vary between 5341 to 10 682 tons of ingredient in Hungary, and 5110 to 10 221 tons in Poland. Although site-specific crop production is compatible with ecological, economic and social sustainability, its real diffusion is not as fast as it could be. In both countries it is suggested to strengthen medium sized farms and encourage shifting them to site-specific farming, supporting machine sharing forms and services offered by other companies.
