There are significant benefits to be gained from reduced and no-tillage in connection to soil protection policies but the unique requrements of such practices create the need for seed drills capable of matching these requirements. It is necessary to reach a quantative representation of the effectiveness of different brands of seed drills in order to chose a suitable drill for the task. The seed drill’s efficiency can be judged after the biological and economic risks of its usage have been evaluated. This paper shows a method which uses the technical data of the seed drill and reaches a cumulative grade to evatuate the biological risk and also an existing software which compares and evaluates the economic risk for a chosen seed drill compared to Cross Slot seed drill. Combining the two types of risk evaluation lets us chose the best type of seed drill for seeding in reduced tillage.
