The present invention provides a new fertilizer comprising a nitrogen source, a phosphate source, and an organic potassium source selected from the group consisting of potassium acetate, potassium formate, potassium citrate, potassium succinate, potassium propionate, animal manure, and combinations thereof. The fertilizer has a neutral to slightly alkaline pH, relatively lower salt index and potentially lower phytotoxicity damage compared to other sources of potassium for fertilizer products. The fertilizer composition may further comprise additives such as sulfur, zinc, boron, calcium, manganese, iron, copper, cobalt, magnesium, or a combination thereof.

The invention disclosed herein is a multifunctional agricultural organic bio-complexed composition comprising essential and non-essential nutritional elements; useful as a fertilizer, nutrient, bio-stimulant, complexing agent, pH controller, pH indicator, pH corrector, hard water salts in-activator, surface tension reducer, Spreader, penetrator, adjuvant, alkaline hard water ill effects mitigator, water conditioner and drip system irrigation cleaner. The invention also disclosed herein a process for preparation thereof.

Solvent systems for the formulation of alkyl thiophosphoric triamide urease inhibitors, that provide stable dispersion of alkyl thiophosphoric triamides and/or dicyandiamide for even distribution (in low or high concentrations) onto fertilizers containing urea in liquid or solid form.

A granular cohered MOP fertilizer having one or more micronutrients, and one or more binding ingredients. The fertilizer is prepared by compacting MOP feed material with one or more micronutrients and one or more optional binders to form a cohered MOP composition. The cohered MOP composition is then further processed, such as by crushing and sizing, to form a cohered granular MOP product containing micronutrients. The process yields a fertilizer product containing micronutrients with superior elemental and granule size distribution without comprising handling or storage qualities.

The present invention relates to functionally effective organically chelated micronutrient and method of preparing the same. More particularly, this invention pertains to method of manufacturing of functionally effective organically chelated micronutrient such as zinc, copper, iron, boron and manganese. The said organically chelated micronutrients are having multiple actions such as plant nutrient and plant protection activity.

Verfahren zur Gewinnung von Wertstoffen, insbesondere Phosphat, aus Klärschlammprodukten, nämlich Klärschlamm, Klärschlammasche oder Klärschlammschlacke, durch Extraktion, bei dem man eine Suspension des Klärschlammproduktes in Wasser, Alkohol, Wasser/Alkohol-Gemisch oder wässriger Lösung herstellt, gasförmiges Kohlendioxid (CO₂) oder überkritisches Kohlendioxid (scCO₂) als Extraktionsmittel in die Suspension des Klärschlammproduktes einleitet, ungelöste Feststoffe von dem flüssigen Suspendiermittel abtrennt, Kohlendioxid aus dem Suspendiermittel entfernt und in dem Suspendiermittel gelöste Wertstoffe ausfällt und von dem Suspendiermittel abtrennt.

A trace amount of a tungstate is disclosed for inhibiting corrosion by nitrogen fertilizer solution, in particular, an ammonium nitrate fertilizer solution, (UAN) in contact with ferrous metal storage tanks, piping, and equipment surfaces. Tungstate added with a dispersant polymer is also effective for inhibiting corrosion.
