Compost is made from decomposed organic materials. A colloid is a liquid with solid suspended in it firmly like, for example, butter, which is cream with fat suspended in it. Completed compost becomes humus. Additional fermentation is needed for it to become colloidal. When compost reaches the colloid state it can be rolled into a rubbery ball. It will continue to compost and feed itself. This process keeps important plant nutrients from being washed away.
Place grass clippings, dry leaves, kitchen scraps and straw into a shredder. One can be rented from your local equipment rental dealer. Shred organic materials into fine particles.
Add shredded materials to large back trash bag. Add 1 cup of lime to the bag. Add 1 quart of water to the bag. Place the bag in direct sunlight during the summer and into a heated garage or basement in the winter. It takes approximately six to 12 months for this to completely breakdown.
Open the bag after six months. Grab a handful of compost. It should form a rubber-like ball. If it does not form a rubbery ball, close the bag and allow the mixture to decompose for six more months.

- Grass clippings
- Dry leaves
- Kitchen scraps
- Large black trash bag
- The finer the particles used in composting, the easier for the decomposition process to turn the compost into colloidal humus.
