A product form comprises an inanimate substrate comprising i) an active agent; and ii) carrier particles including at least an outer surface comprising an organic matter constituent, wherein the said active agent is combined within and/or on the surface of the carrier particles, the carrier particles being a) in dry, particulate form and carrying at least an electrostatic surface charge, and b) being at least substantially uniformly distributed over the outer surface of the substrate.

A coated fertilizer comprises a fertilizer granule; and a coating disposed on a surface of the fertilizer granule, wherein the coating comprises a poly(lactic acid); a second polymer comprising a poly(butylene succinate), a cellulose triacetate, or a combination comprising at least one of the foregoing; and a sealant. Methods of making the coated fertilizer are also disclosed.

The present disclosure is related to a fertilizer (inorganic/organic/natural/synthetic) enriched with acclimatized (preferably halotolerant) effective microorganisms (AEM) and optionally with an organic emulsion (OE). The present disclosure provides a bioaugmented fertilizer enriched with AEM and optionally OE. Provide product (fertilizer) specific AEM, and method for producing such fertilizers. Fertilizer enriched with AEM, OMP, and OE renders it an Integrated Plant Nutrient Management (IPNM) principles based product (fertilizer). This makes it superior in performance over conventional fertilizers (inorganic/organic/natural/synthetic) due to better nutrient use efficiency.

A nitrogen activator additive to stabilize nitrogen fertilizer, where the activator is coated onto the nitrogen fertilizer, is provided. The nitrogen activator additive contains the novel compound ABT-PNB, a potassium compound, and chitosan, and provides controlled release of the nitrogen fertilizer which fertilizes crops using reduced levels of the nitrogen fertilizer and reduces the release of greenhouse gasses. Urea is an exemplary nitrogen fertilizer that can be used in this regard.

The invention relates to formulations for controlled release both in water and in soils, and to the components and processes that enable effective coating of cores in various forms. The technology used for implementing the invention, i.e., multilayer coating of cores with the addition of various additives and active ingredients, enables modulation of release of the active ingredients in the desired times and modes. Release is regulated according to the desired targets. The technology does not use any organic solvent, but is based upon a thermodynamic technology that uses the phase transitions through control of the heat introduced into or removed from the system. The invention uses low-cost compounds, mostly of natural derivation and in any case biodegradable. Hence, the materials and technology necessary for implementing the present invention have a low environmental impact.

A fertilizer composition including a base fertilizer granule with a hydrophobic or super-hydrophobic coating that reduces fertilizer caking and dust formation. The coating can include a roughening component, which creates micron-scale surface roughness, and a hydrophobic coating. Together, the components of the coating act to physically protect water soluble fertilizers granules from the ingress of moisture and from caking, and increase the resistance of the granules to abrasion.

A controlled release fertilizer includes a plurality of prills, each prill within the plurality having a nutrient core including nitrogen (N) and potassium (K), and a coating structured to release nutrients from the core over a predetermined period of time, the plurality of prills having an overall ratio of N:K of about 1:8 to 1:2.

Biodegradable coatings, particles that are coated with such biodegradable coatings, and methods of making such coatings and coated particles. Coatings with urethane linkages, urea linkages, or a combination thereof may be degradable over time with a microbial powder or solution applied to the particle, between layers of the coating, or on top of the coating.
