The case of an arable farm
The plots on this site are interactive. Hover on the plot to gain insights on the most profitable machine size for the given distance and plot size combination at the pointed location. You can turn and pan the plot by clicking and dragging, or zoom using the mouse wheel. Click on the buttons above the plot to display results for other indicators.
For the arable farm, the conversion to organic farming is a profit maximazing choice. The crop production costs of conventional and organic farming are similar with organic farming facing slightly lower costs. The organic farm benefits from lower costs due to differences in weed and pest control as well as fertilization. However, after conversion, there is a considerably high increase in labor requirements which mostly reflects the uptake of livestock and pumpkin production. The gap within each level is due to the choice of the profit maximazing mechanization level. At the gap the mechanization level changes from 102 kW to 200 kW.
With increasing distances, crop production costs and total labor requirements are increasing, followed by an decrease in profit. Increasing plot sizes have a opposite effet: Costs and labor requirements decrease resulting in an increase in profit. The effects of plot sizes and farm-field distances are slightly higher in conventional systems, however hardly visible in the graphs.
