Cover Crop Seed

Testimonial …

“When I decided to start no-tilling and using cover crops I wanted to work with a seed dealer who was into more than just selling seeds. I wanted somebody who was willing to think outside the box with me and come up with innovative solutions to benefit my soils and ultimately my bottom line. I was attending every no-till/cover crop seminar and conference that I could and I kept running into Dave and the folks at Elk Mound Seed. After striking up a conversation that extended into many phone calls back and forth I knew I had my guy. It has been a pleasure talking soils, crops, and anything else when it comes to farming. I believe conservation and production agriculture do not have to fight each other and it is with that motto that I will continue to work with Elk Mound Seed to continue on this path of regenerating my soil health.”
