The college I go to here in Maine offers the students garden beds each year and fortunately I was able to plant in one this year! I am allowed to grow over winter in this bed, so I am constructing a hoop house. This growing season I noticed there was not a lot of fertility in the soil, and I've been learning about green manure and cover cropping, and how they really help with adding organic matter and fertility to the soil. With this hoop house I would like to plant a winter hardy cover crop to grow until mature and then cut down and use as mulch for my vegetables in the spring.
Is this a realistic idea? I figured maybe I could get two rotations/life cycles of a cover crop by spring and start building my soil as soon as possible. Also, any ideas for a good cover crop that provides phosphorus, nitrogen and does not get too tall? My hoop how will probably only leave two or three feet for plants to grow.
I am very new to cover cropping so I could use any advice you have to offer, especially regarding my situation! Thanks
