COVER CROP SUMMIT SPEAKERS
Cover Crop Consultant, Holtwood, Pa.
Making that final decision to adopt cover crops on a farm isn’t an easy one, but it’s a little easier for growers if they start with the right mindset at the beginning.
Pennsylvania no-tiller and internationally renowned cover crop coach Steve Groff will share why it’s important to see where the future of agriculture is moving and how a willingness to strategically try something new is essential to succeeding with covers.
Rancher, Tiffany Cattle Co., Herington, Kan.
Shawn Tiffany will outline how he and his brother, Shane, have evolved their custom cattle-finishing facility — which services more than 32,000 head at two sites — from strictly grazing native Flint Hills pastures to grazing and forage and, finally, adding cover crops for soil improvement.
Tiffany will share important figures on livestock gain and performance document through cover crop grazing, as well as yield benefits to his rotation of corn, winter wheat, silage sorghum and soybean.
Farmer, Austin, Minn.
For many no-tillers in the northern U.S. it’s easy to stick with the same corn/soybean rotation or just seed cereal rye and call it good — but Tom Cotter decided several years ago that’s not good enough.
The Austin, Minn., no-tiller will share how he’s interseeding covers into corn and beans and seeding multi-species mixes after harvest for winter grazing as he backgrounds calves and produces all-natural beef products for the retail market
Soil Scientist, Texas A&M University Department of Soil and Crop Sciences
Many growers in drier environments on the Great Plains could benefit from cover crops but worry that adding covers to their rotation will take too much moisture away from their cash crops and potentially hurt yields.
Soil scientist Paul DeLaune will share the results of two multi-year studies Texas A&M University carried out on the effects of cover crops not only on yields in continuous cotton and wheat systems but also important metrics such as water infiltration and retention, and changes in soil properties and soil microbial activity.
Regional Director of Extension Programs, North-Central Region USDA Sustainable Agriculture Research and Education (SARE) Program
One of the biggest questions growers have about cover crops is how the benefits will pay off for their operation, and the answers often consist of partial budget analyses of seed costs and yield effects by universities that don’t go far enough, says Rob Myers.
The regional director of extension programs for the USDA’s Sustainable Agriculture Research and Education (SARE) program will share results of a new national cover crop economics assessment that will look at how cover crop seeding benefits the entire farm operation — from longer-term effects on crop yields over several years to their impact on fighting herbicide-resistant weeds and soil compaction, to revenue diversification via grazing programs
University of Wisconsin Extension Specialist, Organic Agriculture
One growing method of cover management in no-till systems is terminating overwintering cover crops using a roller/crimper before, during or shortly after planting. This can be an especially valuable tool for organic operations that must avoid using herbicides for this task, or for growers wanting another tool to fight weeds.
Erin Silva will describe the successful organic no-till production techniques that including rolling and crimping cereal rye at soybean planting, which keeps a living root in the soil longer and leaves a mat of plant residue on the soil surface to suppress weeds and build biomass and soil organic matter. She’ll also share some tips for setting up and operating a roller-crimper system successfully in a conventional or organic no-till operation.
Cover Crop Applicator and Co-Owner of Dairyland Aviation
Many no-tillers complain aerially seeded cover crops result in poor stands. But Damon Reabe has spent the last 7 years studying stand failures and says there are some strategies no-tillers can employ to dramatically increase the chances of getting better stands.
The aerial cover crop applicator and co-owner of Dairyland Aviation from Waupun, Wis., will explain the necessary steps to ensure a successful cover crop stand, including what seed species work best when broadcast, the best timing of application, how sunlight can affect success rates and what soils have the greatest success rate. He’ll also touch on some successful work he’s done seeding cereal rye in March into corn and soybean residue to offer an alternative timeline to get a cover crop established before planting.
Farmer, Shenandoah, Iowa
Chris Teachout will outline his progression of cover crop seeding approaches on his 1,850-acre farm in southwestern Iowa — from broadcasting the seed early on to offset planting covers into corn at V3-V4. Then he’ll share yield and biomass data from his on-farm trials last year planting corn at higher populations in 60-inch rows vs. 30-inch rows and seeding cover crops in between the wider rows.
The fifth-generation farmer will also have data to share from planting early soybeans into cereal rye on his farm.
