Deep tillage is even more deleterious to the world' s topsoil supply than previously believed  For example, farmers who till deeply are ten times more likely to lose topsoil to erosion than are farmers who use no-till methods
Results like these make it clear that farmers who now till deeply should strive, by using other topsoil aeration techniques, to incorporate no-till methods instead
Tilling by any method other than deep tillage is not a viable option.
