The present technology relates to a micronutrient fertilizer comprising immediate release and sustained release components contained within a hydrated polyelectrolyte solution. The fertilizer is readily dispersed and stable over long periods of time.

The invention relates to a conditioning agent for reducing water absorption and dust formation of a particulate fertilizer, comprising 10 to 50 weight % of wax, 40 to 90 weight % of mineral oil and 1 to 15 weight % of a resin being mineral oil-soluble and miscible with wax and mineral oil, wherein the agent further comprises 0.1 to 1 weight % of a viscoelastic elastomer selected from the group of polyisobutylene and styrene-isoprene-styrene block copolymer which is soluble in mineral oil and has an average molecular weight of 30.000 to 5.000.000. The invention further relates to a particulate fertilizer composition, preferably a urea-ammonium sulfate (UAS) fertilizer, a urea fertilizer or a calcium nitrate fertilizer, comprising a particulate substrate, preferably an hygroscopic fertilizer, preferably a nitrogen-containing fertilizer, and 0.05 to 2 weight % of said coating thereon for reducing moisture uptake and dust formation of said fertilizer.

The present application relates to a nanoparticle compositions and methods for targeted delivery of a bioactive agent to a plant. In one embodiment, the nanoparticle composition includes a coronatine-coated nanoparticle formulated to deliver one or more bioactive agent through plant stomata. A variety of bioactive agents may be included in the nanoparticles, including one or more bactericides, fungicides, insecticides, acaricides, miticides, nemanticides, molluscicides, herbicides, plant nutrients, fertilizers, plant growth regulators, or combinations thereof.

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.

An activated-release, water-insoluble or slowly-soluble coating is utilized on fertilizers, pesticides, seeds, medicine, and other granules to precisely time the release of the active ingredient of the granules, for purposes such as fertilizer and pesticide release as well as to initiate seed germination. An external stimulus, or activating agent, including, but not limited to, microwaves, ultrasonic waves, X-rays, radio waves, electromagnetic waves, radar waves, sonar waves, magnetic induction, (or pulses of any of the foregoing), specific chemical, bacteria, or fungus organism (such as ionic or non ionic surfactants, organic solvents, specifically cultured bacteria, fungi or catalytic agents) is used to break the coating, thus allowing for the release or germination. An activating device may be mounted on or in a tool bar, cart, or other apparatus pulled by a tractor, all-terrain vehicle (ATV), airplane, helicopter, or other implement and passed over a field, sprayed onto or injected into the soil, when the granule content is actually needed or germination is sought. The present disclosure also relates to liquid fertilizers of complex chemistry that are not readily available to plants; activation will degrade the nutrient compounds to readily-available forms.

The present invention relates to a method for applying biochar to turf and landscape to allow the turf and landscape to be effectively maintained under reduced water and/or reduced fertilizer applications.

The present invention relates to a method for applying biochar to turf and landscape to allow the turf and landscape to be effectively maintained under reduced water and/or reduced fertilizer applications.

The present invention relates to a composite microorganism enzyme, a method for preparing a plant nutrient solution by using the composite microorganism enzyme, and a fertilizer synergist. The method comprises the following steps: mixing fresh kelp pulp with a composite microorganism enzyme; and performing enzymolysis on the mixture of the fresh kelp pulp and the composite microorganism enzyme in an enzymolysis vessel to obtain the plant nutrient solution; the composite microorganism enzyme comprises more than one kind each of cellulase, pectinase, protease and amylase, the mass percentage of the cellulases and the pectinases being far greater than that of the proteases and the amylases. The present method for preparing a plant nutrient solution involves a simple enzymolysis process, mild reaction conditions, low costs and no other chemical compositions during the reaction processes, and maintains more of the active ingredients of the fresh kelp.
