Abstract
A controlled release fertilizer includes a core including plant nutrient particles and a biodegradable coating composition forming at least one layer surrounding the core, the composition comprising cellulose, the at least one layer being structured as a semi-permeable surface membrane configured to release the plant nutrients from the core in a linear manner.
Claims20
A controlled release fertilizer comprising:
- a core including plant nutrient particles;
- and
- a biodegradable coating composition forming at least one layer surrounding the core, the composition comprising cellulose, the at least one layer being structured as a semi-permeable surface membrane configured to release the plant nutrients from the core in a linear manner.
A biodegradable fertilizer comprising:
- a nutrient substrate encapsulated in a cellulosic coating including a plant-based cellulose and having a micro-porous structure including release channels arranged to release nutrients from the substrate in a controlled manner, the substrate and the cellulosic coating being biodegradable.
A controlled release fertilizer comprising:
- nutrient particles, each enclosed in a cellulose-based semi-permeable biodegradable coating, the nutrient particles being structured to diffuse from the fertilizer via the coating, the coating structured to degrade after diffusion of the nutrients is complete.
