Disclosed is a method of producing a fertilizer from a marine source.

Disclosed is a method of producing a fertilizer from a marine source.

A granular fertilizer product having at least two sources of boron having different solubilities to tailor boron availability during the entire growing season of a plant, while reducing the risk of boron toxicity. A first source of boron can include a sodium-based or highly water soluble boron compound such as sodium tetraborate and/or boric acid, while a second source of boron can include a calcium-based boron compound such as colemanite (CaB.sub.3OH).sub.3.(H.sub.2O)) (e.g. when the carrier fertilizer is N- or K-based) and/or boron phosphate (BPO.sub.4) (e.g., when the carrier fertilizer is P-based). The solubility of the first source of boron is higher than the solubility of the second source of boron such that the sources of boron have different release rates into the soil.

Disclosed herein are feedstock materials which can be used for the manufacture of industrial products and consumer goods. The feedstock materials comprise particles of a comminuted paper product having fibrous portions on an outer surface thereof distributed throughout a diagenetically formed mineral aggregate comprising gypsum, syngenite and magnesium hydroxide and/or magnesium sulphate. The feedstock material, and products produced therefrom, is adapted to degrade when buried. Also disclosed herein are methods for producing the feedstock materials, and products produced from the feedstock materials.

The present disclosure relates to a process for the production of potassium sulphate based mineral fertilizers, by means of an exchange reaction between potassium chloride and ammonium sulphate (2KCl+(NH.sub.4).sub.2SO.sub.4<.fwdarw.K.sub.2SO.sub.4+2NH.sub.4Cl) in controlled conditions. The process, subject of the invention, makes it possible to obtain, in a single reaction stage, a crystalline product classifiable as low-chlorine-content mineral fertilizer, containing potassium sulphate, with K.sub.2O in an amount of between 40% and 50% by dry weight, ammoniacal nitrogen in an amount of less than 5% by dry weight and chlorine in an amount of less than 3% by dry weight, with a high potassium-conversion efficiency (calculated as the ratio between what the amount found in the solid main product and the amount introduced as KCl to the reaction with ammonium sulphate) and a by-product, which can be used directly as NK fertilizer (containing nitrogen (N) and potassium oxide (K.sub.2O) both in an amount comprised between 15% and 20% by dry weight) or as raw material for the production of complex fertilizers.
