We’ve used covers on my family farm since 2013. Overall I’d say they’ve been a net positive and provide a lot of value if you own cattle. We’ve used cereal rye and typically have little issues getting it established. We did have issues getting it killed this year for the first time ever. From what I’ve been able to decipher, the issue was the form of glyphosate we used which was power max 3. We planted some triticale this fall and I think we’ll like it from a field value standpoint. We’ve planted some rape seed, red clover, radish’s and turnips. In our geography you better get them established early part of September to give you any benefit as a cover. We seed most of ours with a valmar seeder attached to an aerway. It does a good job. We had to fly some on this year with a drone due to a government program. Flying covers on has been hit and miss from what I’ve seen. We’ve planted into tall rye before. Shark tooth wheels seem to work good. When we got hydraulic downforce on our planter it worked really well planting into the tall rye. We do not use a no-till coulter. We burn the rye down and plant into it. Our closing wheels are copper head poly spike wheels. We’ve had rye wrap around those before. One year was really bad. I believe the year it was really bad, we were planting beans and they were on 15 inch rows and the narrower rows might of had something to do with it but I can’t remember.
Have we seen increases in organic matter? Not really
Have we seen increases in nutrient levels in the soil? No
You can reach out to me with any further questions. I can give you more experiences that I’ve had with covers good and bad. It’s gets to be a lot to post on here.
1. You mentioned livestock with covers. Are you saying silage makes it possible to get cover crops planted early enough to be worth attempting? Or are you using the covers for the livestock, or other?
2. You said covers are beneficial, but then you mention it hasn’t really shown a benefit with this or that. What are the benefits you gain?
3. You allude to getting govt payments for planting cover crops. Would you continue to use them if you had no payments and had to foot the machinery, fuel, and seed costs yourself? Would cover crops be a positive sustainable deal on their own?
I remember plowing down clovers for dad when I was 8 years old, and have continued to grow a small bit of cover crop on this farm ever since. It’s difficult in a northern wet climate, but I’m not against cover crops at all. I’m just curious how one can quantify a gain from them on a large number of acres? I enjoy these threads and you have provided food for thought.
