From the US and Canadian governments. That's why I said "in the US and Canada".

Even US and Canada no-till farming is still around 20-30%. It higher than Europe because of more intense use of herbicides and different farming practices.

Wider use of crop rotation, GMO, farming robots and micro-irrigation might reduce the need for tilling but it is still very far of. Farming is heavily subsidized but still not very profitable. Margins are small and no-till methods are not economically viable for most places.
