Go to the guy in the green hood. Talk to him. He will give you the manure.

Green manure is a crop (clover, field beans, etc) that are not harvested, but are ploughed into the soil to feed a later main crop.

Green manure's nitrogen content is very high, and it will burn growing plants. Green manure is great, on the other hand for starting a compost pile, if you mix it with some plant matter. It's also great for turning into a compost pile which hasn't been composting well. The best use of green manure is to dig it lnto the soil by trenching where it will rot and release Nitrogen.
