Detailed explanation-1: -To compost grass clippings traditionally in a pile or bin: Add dry grass that hasn’t been treated in the last 14 days to your compost pile. For the correct 30:1 carbon to nitrogen ratio, mix about 50% grass clippings and 50% brown material, like brown leaves, branches or newspaper.
Detailed explanation-2: -You can add clippings to the backyard compost pile. Composting involves mixing grass clippings and other plant materials with a small amount of soil containing microorganisms that decompose organic matter. Grass clippings are excellent additions to a compost pile because of their high nitrogen content.
Detailed explanation-3: -The end product is compost – a dark, crumbly, earthy-smelling material. Microorganisms feed on the materials added to the compost pile during the composting process. They use carbon and nitrogen to grow and reproduce, water to digest materials, and oxygen to breathe.
Detailed explanation-4: -Green materials include fruit and vegetable scraps, used tea, coffee grounds, crushed eggshells, grass clippings, green plant cuttings, old flowers and many weeds. Brown materials are things like straw, paper and cardboard, dry leaves, woody prunings and sawdust (but not from treated wood).
