I think you can get Alfalfa pellets at the Feedstore Barbalee.....I myself love mushroom compost, BlackKow (composted manure)
http://www.blackkow.com/, peatmoss and coarse sands in my flower beds...of course I have to add all these goodies, since all I have is limestone and rock with very little soil that the builder threw on the top of those rocks... I wish I can send you my worms...got lots of it here...
