Compost is a great way to go. Hen poop for corn, cow poop for the rest of the garden. Needs to be composted, tho. Fresh stuff stinks and won't grow a good garden until it's broken down to soil again by the microorganisms. I've found that earthworms love the broken down stuff. Hmmm, still dreaming of my acre of garden I don't have. The Indians used fish in the holes they planted their corn in.
We all need some good growing space so we can tell Monsanto to go pound sand! Best exercise in the sun you can get. Satisfaction of growing your own stuff. It's the work that turns out to be fun. IMO work is always fun when you're bettering yourself, have control of your own situation. Gives a person a sense of self sufficiency and independence. (along with a good root cellar)
