Horse manure - composting

Tom Wegner

Local campaigns encourage backyard composting of grass clippings or leaves. Like yard wastes, horse manure and bedding contain the carbon and nitrogen necessary for successful composting. The challenge is to ensure the proper proportions of water, air, carbon, and nitrogen get piled, turned, and aged without contaminants.

Simply piling horse manure is not composting. Composting involves the managed, accelerated decomposition of materials. In decomposition, microorganisms break down organic materials like horse manure into smaller particles. Composting kills weed seeds and reduces pathogens, odors, and volume.
