In this paper, basic principles are presented of how to allocate plots to farms with two factors taken into considerations: zones of differences in distances between farm sites and plots, and lines of equal differences in distances, which de-limit them. Both the boundaries of the zones being analyzed and ranges of their areas constitute a significant condition to correctly plan and perform the process of allocating lands to farms. A requirement necessary to correctly allocate plots to two selected farms is that the plots of those two farms are situated within one zone of differences in distance that delimits the plots belonging to the selected farms. A line of equal differences in distances delimiting the plots belonging to those two farms runs across the delimiting zone provided that those plots are most favoura-bly located in relation to the farm sites. The examples shown in this paper refer to two farms located in the village of Filipowice; they exemplify the optimization of layout of the farmlands, and the routes of lines of equal differences in distances between farm sites and plots, as well as area ranges of zones of distances.
