| Summary: | The model of optimal utilization of arable land presents a new way of farming evaluation. The main map sheet consists of four parts, which logically follow each other. The first part shows which natural conditions (general soil and climatic character, local risk of water erosion) were taken into account in the creation of model crop rotations. The resulting production of biomass according to these crop rotations follows (part 2). The third part evaluates the production, consumption and biomass balance of crop groups in terms of self-sufficiency (food, feed and energy needs). The impact of biomass production on soil quality, according to the balance of soil organic matter, is shown in Part 4. This returns the cycle to the natural conditions of biomass production. The resulting map, therefore, shows a state in which the soil is sufficiently protected against water erosion and the biomass production is sufficient to cover all needs.
