All Soil Health Is Local with Garrett Marsh
There are a lot of similarities amongst farmers, but there is no denying the fact that every farm is different. Never is that more apparent than when you learn about a farming operation in a different part of the country than where you’re from. Louisiana farmer Garrett Marsh shares about some of his early experiences with cover crops, why he switched from flooding to row rice and how that fits into his rotation. Garrett shares about how his lifelong interest in soil eventually led him to cover crops.
“It's worked out really well so far. Like I said, it's cut down on erosion. I hadn't had a whole super lot of weed pressure. So far, it's been working good. I'm kind of wanting to get into some of the other cover crops that cost a little more. Just for the fact of, I want to try to do a little experimenting with the nitrogen savings on it.” - Garrett Marsh
Garrett and his wife farm near Tallulah, Louisiana which is just across the Mississippi River from Vicksburg, MS. His grandfather started out sharecropping in the area, so he is now the third generation of his family to farm that land. They farm around 1700 acres of soybeans, corn, rice, wheat, and cotton. Garrett offers advice to producers considering incorporating soil health practices into their operations.
“Rather than jumping off into it head first and planting every acre you got in it, you know, I would suggest just kind of starting off slow, a couple of fields and experimenting with them. See how you like it. Cause I mean, it's different for everybody. It really is, you know your neighbor is going to do something different than what you are and you just got to find the little niche that's right for you and there's no doubt that it's going to.” Garrett Marsh

Conservation For Both Ecology and Farm Economics with Laurie Isley
We love to talk about soil conservation practices on this show, but it’s always important to frame it in a realistic context that acknowledges farms are businesses. This means that the right thing for the soil has to also be the right thing for the farm’s profitability. Michigan farmer Laurie Isley shares how she’s embraced new practices at Sunrise Farms, from strip tillage to precision technology to biologicals and beyond on today’s episode of Soil Sense.
“We've also found that we continue to be profitable in the same way that we were before using these other practices. And that's really the point we try and get across to the farmers we talk to. Profitability is not this one and conservation this one. They can be very close together. It's not like they're two ends of a spectrum. Some of it isn't that I'm getting a greater yield. It's just, I have fewer costs related to the tillage that I was doing prior to that.” - Laurie Isley
Laurie is one of the owners of Sunrise Farms in Southeastern Michigan along with her husband, Jim and their son Jacob. The family farm grows about 1100 acres of corn and soybeans and implements a lot of different conservation practices including strip tillage, cover crops which they have flown on, filter strips, soil tests, and precision ag practices. Laurie, who also spent decades teaching agriscience at the high school level, now also contributes to the industry as part of the Michigan Soybean Committee and the United Soybean Board, where she is the chair of the Communication and Education Committee.
“It requires people that are open to seeking more information. So I guess my major message to them is don't settle. Be willing to look for what are new opportunities that I can use on my farm that will help me to be more profitable, but also help to ensure that the soil that I leave behind for the generations to come is as good as it possibly can be and still viable for other generations to continue farming in this area.” Laurie Isley

Patience and Persistence Pays Off With Fred Yoder
Improving soil health doesn’t happen overnight, but it’s amazing how a series of small changes, compounded over time, can really make a difference. In this episode, we talk to 4th generation Ohio farmer Fred Yoder about things he’s been implementing over the past four decades to improve his soil health and what he has experienced firsthand that he wants farmers everywhere to experience as well. Along with his wife Debbie and his 2 children, he grows corn, soybeans, and wheat. He also has operated a retail farm seed business for over 36 years and sells seed and other technology products to farmers.
“I think we should be building soil and the things that we're doing today, I think we're building rather than even maintaining, we're actually improving soil. Dad wasn't the first to say it, but I asked him when I bought the farm, any last minute, recommendations. He said, “Just leave it in better shape than what you got it.” And today the farm is the most productive it's ever been and in the best shape it's ever been. And I think that's because of some of the things that we've been doing over the years.” - Fred Yoder
Fred is also a founding board member and now Co-Chair of “Solutions from the Land,” a non-profit that explores integrated land management solutions to help meet food security, economic development, climate change and conservation of biodiversity goals. He also serves as Chair of the “North American Climate Smart Agriculture Alliance,” representing all factions of production agriculture, and working to ensure that farmer-to-farmer education and economics will be the driving force to adapting to a changing climate while feeding the world.
“I look at my soil as my 401k, you won't get instant gratification from it… What they have to be convinced of is the fact if you invest in some of these practices that it'll pay dividends later on down the road. The first couple of years, you have to actually get your soils conditioned for less tillage and for cover crops and things like that. You give me a farmer for three to five years and I'll have him for life because once you go through that transitional change, then all of a sudden it supports itself.” Fred Yoder

Practical Ideas for Building Healthier Soils With John Burk
There is no substitute for experience. Michigan farmer John Burk has a masters degree in crop and soil science, spent 10 years as an ag and natural resources agent for Michigan State University, and has spent over two decades farming full time. Even though he’s been farming full time for over 20 years now, he still remains involved in a lot of cover crop work with the university as well as some conservation districts. His real world experience and knowledge are invaluable in our discussion about the future of soil health.
“Get some green manure back in. You've gotta replenish them soils. You've gotta keep them soils healthy, and you need to keep them in one place so they're not all over the neighborhood. At the same time, I'm gonna tell somebody don't go out tomorrow and this fall and say, I'm gonna plant a thousand acres of rye. You're never gonna do it again. Do a hundred acres of rye. Figure out how you're gonna manage that hundred before you do a thousand.” - John Burk
John shares specifics about his planning strategies and things he has implemented or at least tried over the years. He brings a unique perspective as someone who not only grows corn and soybeans, but also sugar beets and dry edible beans. John says you need to “replenish your soil somehow and tillage isn't gonna do it all.” He recommends cover crops as a natural answer that will provide great benefits to soil health.
“If you really think about it…the more root mass you have in the soil, the harder it is for that soil to compact. Plus it gives more air pockets for the rain to flow through rather than pond on top or pack those soil aggregates together. So that's why I always like to have a bunch of different masses of roots or even the mass up top worked into the soil.” - John Burk
