Cover crops

The cover crops/green manures are up in both the main garden and the field plot. They need to get established before it gets too cold, but they won't do a lot of growing through winter.

Crimson clover is in all the beds in the main garden. It's mainly a nitrogen fixer, but will make tons of growth in early spring and add plenty of organic matter when it's turned under before planting. You can see the winter crops that are left (not as much as I'd hoped with no cold frames).

The field plot cover crop mix is slower to establish, and won't put on much growth at all over winter. In spring it will start early, and grow into a thick, waist-high stand before being cut and turned under in late spring before planting summer crops. This mix contains Austrian field peas (nitrogen-fixer, organic matter), hairy vetch (nitrogen-fixer), cereal rye (deep, penetrating root system and tall stalks for legumes to climb), and canola/rape seed (organic matter). All four will decompose quickly (~2 weeks) after turning under in spring. During the winter, they'll help control erosion and runoff, and keep nutrients from leaching out.

A colleague at work was reading your blog Ty, and commenting on the same thing. Then they all laughed at me and said "Just like his dad!".
Oh well.
