Start some composting bins. I use pallets lined with burlap; three or four of them, and keep one empty.
Put some old moldy hay on the bottom, a layer of chicken poop and shavings with the majority of chicken poop, a layer of green stuff, trimmings, grass and the like, then some more brown matter like more moldy hay and make layers.
Then wet it down well. It needs to have the constant moisture content of a damp sponge. In dry climates like mine, I have to water it at least once a week for a three foot deep compost pile.
Turn it over at least once a week. This is my purpose of the empty bin. I just rotate things in and around.
If your pile smells strongly ammonia, you'll need more brown matter and more turning. Turning keeps it aerated for the microbes. Anaerobes in a compost pile smell like ammonia.
Compost is about ready to use when the red worms appear and are active and the content is dark and smells like loam; a wet forest floor.
A word of warning: If you use petro-chemicals and/or herbicides like Weed and Feed on your lawn don't put grass clippings in the compost bin.
Also if you're watering it with treated water, it would be best to put the water in a bucket for 24 hours to let the chlorine and other chemicals settle. They can kill some of the microbes. The best thing that happened to my composting piles was when I got irrigation water. Or you can make poop tea by putting some poop in a bucket of water, letting it sit a day and then pouring it on the piles.
You'll love making your own fertilizer and your plants will thank you for it.
Good luck, Mary
