<p>A soil product is provided which is inexpensive to manufacture, which uses a base material that is abundant and economical, which is light in weight and thus easy to handle, store and ship, which has desired moisture retention qualities, which decomposes at a relatively slow rate, and which releases a nutrient as it decomposes. The base material is straw and is coated with a water urea formaldehyde resin, to provide slow decomposition of the straw and also providing slow nutrient release as it decomposes. After applying the coating, the coated product is formed into blocks for handling and storage and subsequently ground into particles to provide a soil-like texture for use as a potting soil or nursery bed soil.</p> |
