An ideal way to recycle cottonseed meal that has gone bad is to toss it into a compost pile. Cottonseed meal is high in phosphorus and other macronutrients essential to plant growth. But while cottonseed meal is a nutritious compost addition, your compost pile must consist of more than just meal. Compost piles need a balance of nitrogen-rich material like cottonseed mix and carbon-rich material like straw or dried leaves. The more varied the material, the more nutritious your compost will be.
Add the cottonseed meal to your compost pile.
Add twice the amount by volume of carbon-rich compost material.
Turn the compost pile with a shovel until the ingredients are mixed well.
Repeat steps 1 through 3 each time you add cottonseed to your compost bin. Stop adding to the compost bin once the bin is full or the material in it reaches between 3 and 5 cubic feet.
