One or more embodiments of the present disclosure provide a special water-soluble fertilizer for delaying decay of a Huanglongbing (HLB)-affected tree. The raw materials of the special water-soluble fertilizer may include, in parts by weight, 3-5.5 parts of ammonium polyphosphate, 7.0-12 parts of ammonium nitrate phosphorus, 13-22 parts of potassium nitrate, 7.5-13.5 parts of ammonium sulfate, 0.8-1.5 parts of urea, 10.5-18 parts of EDTA chelated calcium, 12-21 parts of calcium magnesium nitrate, 3.5-7 parts of citric acid and 150-400 parts of straw vinegar; and a solid content of the straw vinegar may be greater than or equal to 15%. The raw materials may further include 1.3-2.5 parts of EDTA chelated manganese and 1.5-3 parts of manganese sulfate monohydrate. The raw materials may further include 0.25-0.5 part of disodium tetraborate pentahydrate.

Methods and system for increasing the water solubility and availability of zinc in granular fertilizers using acid treatments. The treatment of granular fertilizers with an acidic solution increases an amount of water-soluble zinc, which in turn, increases the efficiency of zinc uptake and reduces the costs and equipment otherwise needed to mitigate zinc deficiencies.

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 containing wax. 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.

An agricultural product as well as its manufacturing method, the product being solid, disintegrable and including at least one agricultural active ingredient and one matrix based on a plant-origin material, the matrix having a plant protein content of at least 30% by weight relative to the dry weight of the plant-origin material and a lipid content of at most 10% by weight relative to the dry weight of the plant-origin material, and being present in the product in a proportion of at least 75% by weight relative to the weight of the product, and the agricultural active ingredient being dispersed, in a homogeneous way, in the matrix, the product having a density from 1300 to 1500 kg/m.sup.3.

Disclosed herein is a composition comprising fertilizer particles being coated with at least two layers of superabsorbent polymers such that leachate of nitrogen in the soil is substantially decreased.

Interpolymers useful for mixing with a fertilizer for the purpose of enhancing the efficacy of fertilizer nutrients in agricultural applications; and methods of inhibiting the precipitation of, and/or dispersing, inorganic elements in the fertilizer.

The present disclosure describes a combination of at least two compositions in which, the first composition includes one or more active agents and one or more non-aqueous solvents, and the second composition includes a sulfopolymer. The combination of compositions can further comprise a rosin. The non-aqueous solvent can be a water-immiscible solvent, such as oil. The present disclosure also describes the use of the combination of compositions to kill pests around plants or to increase the growth of plants.

A controlled-release fertilizer composition includes coated fertilizer particles having granules substantially encapsulated with a polyurethane coating layer formed from a polyol composition and an isocyanate curing agent. The polyurethane coating layers include inorganic particles. Methods of making and using the controlled-release fertilizer compositions are also disclosed.

A particle is provided that includes 5 wt % to 90 wt % of agricultural biomass, combustion residues, biosolids, or a combination thereof. A binder intermixed with the agricultural biomass, combustion residues, biosolids, or a combination thereof retains the mixture in the form of a particle. The resultant particle creates a use for existing waste streams while also improving soil quality. A process of stabilizing agricultural biomass, combustion residues, biosolids, or a combination thereof particles is also provided that includes combining agricultural biomass, combustion residues, biosolids, or a combination thereof with mineral and/or synthetic chemical fragments having a bulk density of greater than about 40 pounds per cubic foot and a sizing of about 100% passing through a 30 mesh screen and about 50% or more passing through a 200 mesh screen. By adding binder, a particle is formed that is deodorized and/or stabilized.
