Home Composting
Have you ever walked through a forest and smelled a wonderful earthy smell? That odor comes from humus on the forest floor. Humus comes from decomposed organic matter (rotted plants and animals). Organic matter is decomposed by soil microorganisms into elements useable by plants. Compost is partly decayed organic matter and is used to increase the humus content in soil.
Why Compost? Compost is an essential component of fertile soil. It affects physical properties of soil such as structure, water retention, and erosion resistance. - Composting is easy and can speed up the natural decomposition process.
- Composting saves money and disposal space.
- Compost protects the aquifer by reducing the need for synthetic lawn and garden chemicals because compost is a natural fertilizer and protects plants from disease.
Types of bins - Holding bins
- Turning bins
- Tumblers
When buying or building a bin, make sure the dimensions are between 3’x3’x3’ and 4’x4’x4’ for optimum composting - too small and the pile won’t heat up; too large and the pile can become anaerobic and smell bad. Compost Uses - Top dress lawns
- Mulch plants and trees
- Dig into clay or sandy soil to improve texture
- Mix into potting soil
