PLOTTING SUCCESS. A 5-year cover crop trial has provided anecdotal on-farm evidence of significant increases in water infiltration rates, and yield and revenue benefits in dry years. Water infiltration has increased twofold in areas with cover crops. In the drought of 2021, the three-species mix provided $94 per acre more than the control without covers.

Cover Crops Pay Big Time In A Drought

Born into no-till, Willis Jepson of Orlinda, Tenn., added cover crops to a legacy of building resilient soils that helped crops fare better against drought.

I’ve been no-tilling 45 years. That’s also my age. No-till is all I’ve ever known as my dad and grandfather were early adopters of the practice. 

Harry Young — the original no-tiller — lived just an hour due northwest of our farm. Following his example, no-till double-crop soybeans were quickly adopted in our area with most using the original Allis Chalmers no-till planters. Dad and my grandfather were quick to adopt no-till soybeans, too, advancing to no-till corn soon after.

In the 1980s, the area extension and Miles Farm Supply started working on no-till wheat. They launched Opti-Crop consulting for intensive wheat management. We used that resource to get into no-till wheat, too. By the early 1990s, my predecessors had purchased a Great Plains no-till drill and had eliminated tillage from the operation apart from tobacco and watermelons.

We certainly took our lumps being early adopters of no-till. Things are much better today. Modern wheat is bred to better work in high residue no-till situations. Current varieties are less susceptible to disease, and there are more herbicide and fungicide options available. While it was a struggle early, today my no-till wheat will produce the same or better than wheat seeded into worked up ground.
