A University of Kentucky study titled "Productivity benefits of cereal-legume cover crop mixtures under variable soil nitrogen and termination times" suggests that mixing cover crops is a beneficial strategy for modern agriculture.
We know cover crops can provide a physical barrier on top of the soil to smother and suppress emerging weeds. But many researchers and farmers worry and wonder how that same physical barrier might influence preemergence soil residual herbicides, which must reach the soil to control emerging weeds.
Cover crops are being sprayed with herbicide to make way for cash crop growth. What will happen to the residue remaining on the soil surface? Read more in this article from University of Minnesota Extension.
Whether from cover crops, manure or plant fodder, residues add fertility and organic matter, and help no-till soils develop improved soil structure, increasing infiltration and moisture conservation. Read more in this article from Lancaster Farming.
Hear from long-time South Dakota no-tillers as they discuss how cover crops impact the transition to using no-till, which cover crop species help better utilize soil moisture, why cover crops are growing in popularity, and more.
These numbers can have a direct affect on our nitrogen use and can help us be better managers in the context of overall soil health. There’s more to it than just understanding the C:N of a particular cash crop or cover crop residue. That’s where microbes come in to play. Read more in this article from Lancaster Farming.
Cover crops have a well-documented role to play in suppressing troublesome weeds. But what happens as those cover crops degrade? Read more in this article from the Weed Science journal.
Holtwood, Pa., no-tiller Steve Groff no-tills pumpkins with this Monosem planter that includes Pequea’s Residue Slicers, which cut through rolled-down triticale and hairy vetch ahead of the row units. He no-tills pumpkins in 45-inch rows between Memorial Day and the end of June.
Nick Vos is pushing to overcome moisture challenges on his farm in southwestern Kansas by no-tilling and using covers to recycle available nutrients and keep his sandy soils protected.
After starting out with strip-till in 2014, Vos has gone to 100% no-till on the vast majority of acres and says he’s addressed erosion and nutrient issues and seeing some relief in irrigation costs.
The National No-Tillage Conference returns January 7-10, 2025!Build and refine your no-till system with dozens of new ideas and connections at the 33rd Annual National No-Tillage Conference in Louisville, Ky. Jan. 7-10, 2025. Experience an energizing 4-day agenda featuring inspiring general session speakers, expert-led No-Till Classrooms and collaborative No-Till Roundtables.

Last week we had boots on the ground at the Big Soil Health Event in Cedar Falls, Iowa where agronomist David Kleinschmidt emphasized the importance of considering Carbon to Nitrogen ratios of cover crops and residues.
