Waste diluted sulphuric acid from titanium dioxide production is converted with calcined magnesite into fertilizer-grade magnesium sulphate.

Fine manganese-sulphur particles improve suspensibility and distribution in micro-irrigation while supporting efficient plant uptake and yield.

Fine manganese-sulphur particles improve dispersibility and suspensibility, boosting nutrient uptake while avoiding uneven distribution in drip irrigation.

An oxygen-releasing fertilizer with biostimulant raises rhizosphere dissolved oxygen to support root respiration, yield, and soil health.

An aqueous wax dispersion with clay and an MgO protective layer keeps NBPT stable on fertilizer granules while reducing ammonia loss.

Sorbent treatment removes refinery hydrocarbons from sulfur-based aqueous compositions, preventing odor return and preserving clear fertilizer products.

Magnesium sulfate stabilizes nBTPT in particulate urea during storage, preserving inhibition and reducing ammonia volatilization.

Manganese salts, elemental sulphur, and excipients form water-dispersible granules or suspensions for more uniform micro-irrigation delivery.

Conventional iron fertilizers oxidize and leach after rainfall; FeSO4, nZVI, and Fe3O4 nanoparticles combine for rapid relief and prolonged iron availability.

Magnesium oxide is inexpensive but poorly soluble; calcium nitrate melt processing creates homogeneous granules with controlled magnesium release.

This case forms crystalline magnesium sulphate-urea phases with controlled water addition to preserve granulate strength and reduce caking.

This case replaces calcium oxide with magnesium oxide to form soluble magnesium sulphate and reduce fertigation clogging risks.

Ferrous ammonium sulphate hexahydrate sequesters soil oxygen to stabilize ammoniacal nitrogen in complex fertilizers.

A multistage desalination process uses phosphate precipitation to remove scaling minerals from seawater before reverse osmosis filtration.

Water insoluble macronutrients combine with low viscosity hydrocolloids to enhance suspensibility and dispersibility in organic formulations.

Replacing oil-based carriers with a water-miscible organic liquid resolves viscosity issues at low temperatures while enabling easy equipment cleaning.

Alkaline additives shift granule pH to neutral, stabilizing phosphoric acid amides that degrade in acidic environments and reducing nitrogen loss.

Compacted composite granules merge polyhalite with potassium sulphate to provide chloride-free nutrients while maintaining structural integrity.

A coating film-forming composition containing an aromatic compound with an amino group and a thio compound creates durable metal surfaces.

A chemical drying method converts wet struvite into a dry fertilizer product using magnesium and phosphate sources.

A water-soluble polymer mediates urea and ammonium nitrate particle interactions to prevent caking.

Attapulgite and kaolin suspension agents prevent nutrient precipitation, enabling high solids carrying capacity without settling.

Segmenting granular magnesium fertilizer into fine powder overcomes slow breakdown and limited soil coverage, ensuring rapid root access.

Dissolving magnesium hydroxide in laundry wastewater eliminates granulation strength-disintegration trade-offs while providing cost-effective soil treatment.

Composite straw carbon loaded with metal oxides removes phosphates without causing pipeline blockage.

Removing inhibitory inorganic salts via ion exclusion and crystallization to boost enzymatic hydrolysis efficiency.

A chemical process converts carnallite into potassium sulphate using sodium sulphate precipitation and flotation separation.

Magnesium sulphate mediates chemical interactions to stabilize phosphoric triamide inhibitors, preventing ammonia volatilization during storage.

Calcined magnesite replaces organic binders during granulation, yielding high breaking strength and immediate water-soluble magnesium availability for crops.

Aqueous magnesium hydroxide suspension with organic anti-foaming agents maintains high particle concentration.

Phosphoric acid and monopotassium phosphate maintain solubility with high calcium or magnesium concentrations without forming precipitates.

Metal oxide and clay particles adsorb phosphorus to buffer release, preventing leaching losses and reducing environmental pollution.

Molten sulfur acts as a binder and lubricant during potash granule compaction, reducing pressing force while improving mechanical stability.
