Do a search for Gabe Brown's cover crop seed mix, he does 14+ different seeds. On 5 acres, you don't need more than one bag of anything but maybe oats or wheat. You can buy bird seed and
feed oats from the farm supply, and
deer plot mix for clover and chicory, and grocery store bulk. Anywhere you can get them, cost isn't a big driving factor as much as just get the seed in the right quantity.
Don't till. Maybe a little disking if you have to to incorporate the seed, but any tillage reduces organic matter and releases
carbon to the atmosphere.
I have seeded 30 acres with a riding
lawn mower, pull behind spreader, and a scrap of
cattle panel and old tires as a drag. I have also over seeded the same field walking with a bag of seed and a $10 handheld Scotts spreader.
