The invention relates to the technical field of agricultural planting, in particular to a controlled-release bacterial fertilizer for peanuts and a preparation method of the special controlled-release bacterial fertilizer. The special controlled-release bacterial fertilizer is composed of an inner layer and an outer layer; after the outer layer is released completely, the inner-layer network structure gradually absorbs water and preserves moisture, and has good slow release and controlled release properties, thereby achieving the gradual release of the inner layer, high fertilizer utilization rate, exerting the efficacy of the microbial agent and facilitating the large-area promotion.

In embodiments, the present invention relates to liquid formulations containing hydrophobic, biodegradable polymers disperse within a Non-aqueous Organic Solvent Delivery System (NOSDS) that is designed to coat fertilizer granules with a hydrophobic film utilizing simple application equipment such as mixers, blenders and tumblers. This film can impede the dissolution of fertilizer components by water improving fertilizer efficiency. The NOSDS can be aprotic solvents, protic solvents and mixtures of prone and aprotic solvents which are environmentally friendly, have flashpoints above 145° F. and we inherently rated safe for contact with humans and animals. The hydrophobic polymers an the reaction product of aldehyde(s) and nitrogen containing compounds.

A controlled release fertilizer containing ammonium polyphosphate includes fertilizer core particles and fertilizer envelopes coated on a surface of the fertilizer core particles respectively. P (phosphorus) is only from ammonium polyphosphate, and ammonium polyphosphate has a degree of polymerization in a range of 5 to 20. A preparation method of the controlled release fertilizer includes steps of (1) weighing the phosphorus source, the nitrogen source, the potassium source and the multiple metallic medium and trace element sources in the above weight parts, pulverizing, and obtaining powders by sieving through a sieve with a mesh number of 80; (2) preparing fertilizer core particles; (3) preparing polyurethane envelopes on a surface of the fertilizer core particles respectively, and (4) adding the agglomerant in the above weight parts into the fertilizer core particles coated with the polyurethane envelopes and cooling to 20° C.

There is provided a nitrogen fertilizer granule in which the nitrogen release can be timed and the nitrogen release rate can be controlled according to the needs of the plants to be fertilized. The smart release nitrogen-containing fertilizer granule comprises a nitrogen-containing fertilizer core; an organic functional layer covering the core, wherein the organic functional layer comprises at least one functional organic compound that is an enzyme inhibitor, a microbial suppressor, a phosphorus solubilizer, and/or a plant hormone; a controlled release layer covering the organic functional layer, wherein the controlled release layer comprises water-swellable copolymeric nanoparticles; and an anticaking layer covering the controlled release layer, wherein the anticaking layer comprises water-insoluble copolymeric nanoparticles.

Disclosed is a method of coating fertilizer particles with a coating, the method comprising providing fertilizer particles in a coating unit, one or more steps of applying a coating layer by applying one or more coating components to the fertilizer particles in the coating unit, and at least, partially curing or hardening the coating layer, wherein said curing or hardening involves a chemical reaction of said one or more coating components, discharging the coated fertilizer particles from the coating unit, optionally after a final cure or hardening step, wherein the coating unit comprises a stationary frame and at least two movable elements.

A particle is provided for delivery of humics, and biochar that is water-dispersible into constituent granules. The resulting particles are amenable to broadcast application, for example via rotary or drop spreader. As a result, a dust-free particle is formed that simultaneously addresses the prior art problems of the friable nature of humics and the sooty dusting property of biochar to facilitate ease of handling, broadcast field spreading, and gain the synergistic effects of dosing soil with both humics and biochar. The particle provides improved storage capabilities for materials improving the quality of the delivered material and decreasing negative storage consequences such as odor emanation or degradation. The resulting particles upon dispersion have a pH of between 3.3 and 8.1.

The present invention relates to improving the efficacy of man-made and/or natural organic-based animal manure fertilizers by administration of an organic solvent formula containing polyorganic acids and/or their salts. The formulation liberates nutrient(s) that are normally bound in the soil as insoluble salts and complexes. These delivery formulations also provide an environmentally sound and inherently safe solvating system that improves diffusion of polyorganic acids to the granule fertilizer. These delivery formulations enable safe storage, transport and subsequent application or blending with solid or liquid fertilizers. The combined formulation and fertilizer can be applied to soil to provide improved efficacy of fertilizer by liberating nutrients bound in the soil for uptake by plant life.

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.

The present disclosure is related to a conditioning agent for reducing water absorption and dust formation of a particulate fertilizer, comprising 50 to 60 weight % of wax, 30 to 40 weight % of oil, 1 to 15 weight % of a resin being oil-soluble and miscible with wax and oil, and optionally 0.01 to 2.0 weight % of a viscoelastic elastomer which is soluble in oil. The conditioning agent may be applied to a particulate substrate, in particular a fertilizer particulate substrate, to reduce the moisture uptake and the dust formation of the substrate, in particular wherein the substrate is blended with other particulate compositions.
