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.

Biodegradable polymers on fertilizer nutrients

An ammonia capture and recovery system comprises five process steps, including an ammonia removal step, an ammonia recovery step, a product granulation step, a granulated product wax-coating step, and a granulated product encapsulation step. These steps are modular in that multiple approaches are valid for each step if it meets the process requirements for the next influent. Also, a method of taking ammonia-containing wastewater and producing several water fractions (preferably of decreasing volume and increasing purity) and a time-release ammonium-containing fertilizer, resulting in a sustainable nitrogenous fertilizer product that reduces fertilizer use and subsequent nutrient runoff while being produced from wastewater and not fossil fuel or hydrogen sources.

Production of nitrogenous fertilizer from wastewater

This invention relates to the art of fertilizers and, more particularly, to a coated granular fertilizer in which the dissolution rates of water-soluble fertilizer components are controlled by coating or encapsulating a granular fertilizer. The coating for the timed-release fertilizer is derived from plant cellulose extracted from hemp cellulose, sugar cane cellulose, or other plant-based cellulose.

A method of hydroponic growing of plants comprising hydroponically growing the plants in the presence of a controlled release hydroponic fertilizer composition. The hydroponic fertilizer composition comprises a polymerically coated controlled release fertilization nutrient formulation which further comprises micronutrients and optionally chelated iron.

Method of hydroponically growing of plants

A method of hydroponic growing of plants comprising hydroponically growing the plants in the presence of a controlled release hydroponic fertilizer composition. The hydroponic fertilizer composition comprises a polymerically coated controlled release fertilization nutrient formulation wherein the coated formulation has an N-P-K ratio wherein the N-K ratio is substantially balanced and further comprises micronutrients and optionally chelated iron.

Method of hydroponically growing plants

A fertilizer composition is adapted to stage the controlled release of nutrients such that the composition need only be applied once in a plant's growth cycle, but with individual nutrients releasing at predetermined, staged intervals targeted to the precise needs of plants. Timed release particulate materials are blended to form the composition. The nutrients include a magnesium source (Mg), a potassium source (K), a nitrogen source (N), and a phosphate source (P). The composition is adapted to release each fertilizer nutrient over a period most beneficial to plants' physiological growth.

Compositions for the staged release of nutrients to plants

A polyurethane encapsulated, slow release fertilizer with a coating based upon an isocyanate component and an isocyanate-reactive component comprising a polyether polyol. The process for producing such particles comprises applying an isocyanate-reactive component comprising a polyether polyol onto fertilizer particles to form coated fertilizer particles, applying an isocyanate component onto said coated fertilizer particles; and forming the polyurethane encapsulated fertilizer particles.
