My father is a pigeon fancier and uses pigeon manure to keep his lawn green and lush.
Step 1: Submerse 1 part pigeon manure (enclosed in a mesh bag) to approx. 25 parts water.
Step 2: Leave to stand for 2 days, the water should have a pale yellow colour to it, if it looks dark add more water.
Ps. DON’T ASK FOR MANURE ON A RACE DAY!
