Experts from Missouri and Iowa academic institutions weigh in on the benefits of no-till in this piece from Missouri Farmer Today. While almost all praise (and use) no-tillage systems, they admit the positive benefits (soil absorption, for one) are hard to quantify monetarily.
Most no-tillers won’t want to hear it, but some University of Nebraska research indicates an occasional limited tillage pass won’t seriously damage no-till’s favorable soil structure. But with herbicide costs increasing significantly this year, we’ve heard that a few no-tillers are thinking of using a light tillage pass as a weed control option.
By monitoring crops through machine learning and satellite data, Stanford scientists have found farms that till the soil less can increase yields of corn and soybeans and improve the health of the soil.
Edge-of-field monitoring on 17 farms in Wisconsin and Minnesota highlights the need for no-tillers to apply ‘P’ under the soil surface and sample soils at varying depths.

University College Dublin reports that conventional tillage is severely damaging earthworm populations around the world, and the deeper the soil is disturbed, the more harmful it is to earthworms.
Tillage may get you in the field faster, but it also disrupts mycorrhizae fungi networks, which relay nutrients and compounds to plants, says Grainews.
A few months back, Ohio State University agronomists produced a website article suggesting that no-tillers consider limited tillage. They felt numerous concerns with soil damage, weed control and disease pathogens and insects that survive on crop residue could be remedied with light tillage.
