Nutrient yielding bio-renewable controlled release fertilizer coatings |
| 摘要 |
Animal waste is processed to form a biomaterial that is employed as a coating layer for typical fertilizer particles. The biomaterial coating layer can be used neat or with additives and serves to do one or more or any combination of the following: (a) impart a slow or controlled release property to the fertilizer, (b) prevent or reduce the tendency of the fertilizer particles to cake together, or (c) prevent or reduce the tendency of the fertilizer particles to create dust. The biomaterial coating layer can also release nutrients when used as part of a fertilizer composition. |

1. A fertilizer composition comprising:
a plant nutrient core containing at least one water soluble plant nutrient; and a biomaterial coating layer formed of a biomaterial produced by subjecting animal waste to a pyrolysis reaction, the biomaterial being a resinous thermoplastic substance liquefiable upon heating and the biomaterial imparting a slow release property to the fertilizer. |
