In europe if you want organic on the cheap, there's nothing better than this:

Zip, Interesting site. The product that came up on the link has an NPK of 6-8-15 and is made od 80% Seabird Guano and 20% Chicken Manure. Might use that on my Surrogate garden #2 next year.

Another product I'm using the year is Effective Microorganisms (EM). Check out the site for some interesting products.

On the italpollina site it says: RAW MATERIALS: Guano, chicken manure, feather meal, stillage and kieserite.
Not exactly sure where the high K comes from from those ingredients.

Effective microorganisms sounds pretty good for my containers.

zip and Ami, many thanks for those links!
