Chicken manure, also known as poultry manure, is one of the most highly prized manures for gardening purposes, according to the University of Florida. It has been used for years as a source of nutrients for plants and to amend soil. Chicken manure has different nutrient amounts, depending on the type of chicken manure you get: broiler chicken manure or layer chicken manure.
Figure out the nutrient value of the chicken manure before you apply it. (ref 2) Send a sample of the manure to your local university's horticultural department for a nutrient value test.
Calculate the size of the land you are applying the chicken manure to and what kind of nutrients the crops need. Some crops need more chicken manure applied, such as corn and grasses, while vegetables need less. (Ref 1)
Place the chicken manure in your manure spreader. Add between 100 to 200 lbs. of manure per acre to your manure spreader depending on the crops. (Ref 1)
Drive the manure spreader over the area in which you wish to apply it. Turn on the manure spreader and put your foot on the gas. Press the button or pull the lever to release the manure once you are over the area in which you wish to apply it. Drive the manure spreader slowly in a straight line down one end of the area in which you are applying the manure. Turn around at the end of the area and drive in a line next to the one in which you already spread manure on. Keep driving the manure spreader back and forth over the given area in this fashion until all of the land is covered with manure. Do not cover the same area in manure twice.
