Having some empty spots in the field last summer we decided to experiment with cover crops. This so called green manure will bring beneficial nutrients to our soil, so next season we can use this space for planting vegetables, which require a lot of nutrients. We will make sure to include cover crops in our plants rotation every season.
To cover our soil we used milo-soybean mix, sudan grass and buck-wheat.

Buck-wheat next to corn

Sudan grass
This fall we also planted some winter hardy hairy vetch, which is a good nitrogen fixing legume.
