Composting: An Alternative for Livestock Manure Management

Composting is more than just piling the mate-rial and letting it sit, however. Composting is the active management of manure and bedding to aid the decomposition of organic materials by micro-organisms under controlled conditions. Efective composting is afected by four major factors: Aeration. Nutrient balance.
