Actually, alfalfa is a nice choice.  You might want to reconsider mowing
before you till to reduce ware-and-tate on your tiller, reduce tangels
in the tines, and to speed decomposition.  Alfalfa (Medicago sativa) is
kind of pretty.  It has clusters of small purple flowers.  I'd say the
best characteristic of alfalfa is that it grows very deep roots that
will bring up potash from deep within the soil.  Often there is plenty
of K in the soil but it is not available to the more shallow rooted
garden plants.  K is also very easily leached from the soil by watering
and rain.

You might even want to try a mix of cover crops.  If you plant just
about any vetch (genus Vicia) you'll get some nitrogen fixing results as
well.  Although legumes do have some good N fixation qualities, they can
become a nuisance.  Of course this is true of most cover crops that you
let go to seed.  You might even want to try several different cover
crops in the same season.  Grow some vetch and then till in under.  Then
grow some alfalfa and then till it under.  Oh, by the way, vetch also
has pretty little purple colored flowers.  If you want more information
on cover crops, send a request via E-mail and I'll get my literature
from home; it's fairly comprehensive.

The following is a list of cover crops/green manure crops that you may
find useful.  This material was extracted from Rodale's Organic
Gardening "Best Ways To Improve Your Soil" which Rodale Press, Inc gave
me at no cost.

Other sources that I've found useful are Rodale's Organic Gardening
"Today's Best Gardening Ideas", and _Rodale's Illustrated Encyclopedia
of Gardening and Landscaping Techniques_.  I'm not selling Rodale Press,
Inc.

Keep in mind that the characteristics of each green manure crop will
vary according to climate and growing conditions.  Before resorting to
the seed sources listed, you may want to check out local garden centers
and farm supply stores for varieties that will grow best in your area.

Contact your Cooperative Extension Service for local planting dates.
