Who have you seen or heard campaigning against tillage?
Of course companies who manufacture herbicides will promote them to no till farmers,
but as you see below, long term no till will reduce the need for herbicides. It
certainly has on my farm.
If you talk with any soil scientist, he will tell you that most tillage has a
detrimental effect on the soil. Tilling the soil might benefit the farmer in some
way, but not the soil and the critters who live in it.

Alot of farmers (especially the conventional) are aware of this and are doing
something about it now. I've found the detrimantal effects of tillage to be an issue
that a good many sustainable farmers ignore. The moldbord plow has caused
significant damage to the quality of soil.
