A few reasons:
First off, we need to improve our soil. Our land has been row cropped for quite a few years and the soil is in need of some serious TLC. We can compensate with lots of purchased compost like last year but it's a pricey way to do it. We have our own compost but still not enough. So we must till and do lots of work to loosen up the soil down 2-3 feet and add organic material to the soil and pull up rocks. We're going to have to do that one patch at a time. So less members = less patches. It's going to take a while before we can move up to a larger CSA base as we need to get a good acre or so of soil worked.
Second, we need to learn how to use row covers for spring crops and drip irrigation for summer and a smaller area is better to learn how to do this.
Third, we like the small CSA. Last year we started to find out what you liked and we tried to grow what you asked for (this year I've learned the secrets for Kohlrabi so it'll be better) and so we really want to make sure each person gets what's fresh as well as extras that you like.
So, send Mike an email if you are interested. The deadline for signing up is Feb 15th. We are only taking 8-14 folks for next year so sign up now. If you can't decide by Feb 15th, we'd be more than happy to give you our recommendations for another CSA in the area if you want to join one after Feb 15th.
