Pesticides contaminate the soil by attacking all life living in it.
Instead of forcing farmers to abandon "traditional" farming methods, a scheme based on incentives such as tax reduction, improved acces to subsidies,... could be proposed to farmers enganged with the reduction of the use of pesticides in their exploitations.
This could be easily done in EU at least since the purchase of pesticides is recorded. I am sure this could also be applied to many other countries around the world.
