Welll, it all depends on the size of the garden you have, the weather, etc. I can tell you how I do it. Not saying its the ideal - I don't do all the fancy aeration/additives stuff - but it works for me.

I have a 55 gal plastic barrel with a removable top. It sits in the shade by the garden shed. I fill it with water about the time I do the spring tilling. I fill all the old cotton tube socks that have gone to the darning pile over the winter (I have read that some use pantyhose) with finished or almost finished compost, tie off the tops (usually about 10 of them) and toss them in the barrel. Put the top on and let it sit. As needed I dip out a bucket full, dilute it as needed (usually at least 2:1 or 3:1) and water with it or spray for foliar feeding. About mid-summer I refill the barrel and add some fresh socks. ;)

Hope this helps.

Dr. Elaine Ingham says to make compost in a 5 gallon bucket you need 2-1/2 gallons of compost. The article below was in an old issue of Kitchen Garden and is by Dr. Ingham, although this may be more information than you want.
