Direct benefits information:
Biedermann calculated for corn possible savings of 416 €/ha, which means 43€/t. By reducing tillage, a farm can save up to 10 000 €. When tillage is completely abandoned, savings up to 24 000 € are possible. Reasons for this are: less working hours (5 €/t wheat for salary instead of 14), less fuel consumption (40 l/ha instead of 96), less fixed machine costs. The additional consumption of herbicides and fertilizers is easily compensated and included in the calculations.
Costs investment information:
Biedermann made its economical monitoring for 100 ha agricultural holding with different crops: winter wheat, winter barley, winter canola, corn, sugar beet and cover plants. He calculated the "cost for doing work" that means: salary (12 €/h), variable costs for machines (fuel, maintenance), fixed cost for machines (interest, depletion, assurance) and means of production (fertilizer, herbicides). When tillage is reduced the farmer should consider selling some of his tractors and increase the operating grade of his machines. The seeding machine is very expensive and in the same time a key element. The farmer should consider to buy it either used, to outsource the seeding or to use it in cooperation with other farmers. As an example, the costs are given here for direct seeding of wheat with a corn yield of 6t/ha.

In his calculations, Biedermann considered an additional consumption of herbicides (18 € per ha) and fertilizers (15 kg N/ha í 1,05 €/kg) for direct seeding.

Costs total information:
These are the "costs for doing work". With direct seeding the farmer saves 37 €/t compared to conventional tillage. When mulchseeding is done in an cooperation savings are 19 €/t and mulchseeding with own machines leads to an saving of 10€/t.
Information on Ecosystem improved biodiversity:
When no tillage is applied, the number of earthworms is multiplied by 5. The symbiosis between roots and rhizobiaceae is improved as well. Moreover, the plant roots are able to create a more complex horizontal and vertical network.
Ecosystem provisioning services:
Information on Ecosystem provisioning services:
In the first years when reduced tillage measures are applied, there can be less yield of crops on the fields. However, this is often balanced since there are less expenses for fuel, and less working time needed.
