How to Compost at Home

2. Wet Green Compost Materials

Green materials are the wet, nitrogen-rich ingredients that feed the microbes doing the work. Grass clippings are very high in nitrogen and work well layered into a pile. Manure from horses, cows, chickens, rabbits, and goats adds nitrogen along with other nutrients, and bat guano is especially nutrient-dense, prized by some gardeners as a top fertilizer. Other greens include fruit and vegetable scraps, coffee grounds and paper filters, plant cuttings, flower tops, and seaweed.
