The present invention discloses biomass compositions for improving shelf life, increasing fruit water retention, and/or decreasing needle-drop in conifer species and methods for making the same. The composition comprises pasteurized microalgae selected from Chlorella, Aurantiochytrium, Scenedesmus, or any combination thereof.

There is provided herein a granule comprising Polyhalite and phosphogypsum, in a ratio of between 40:60 to 60:40, respectively.

There is provided herein a fertilizer granule comprising Urea, Polyhalite and Ammonium Sulphate.

A method for producing potassium chloride granulates from a crystalline potassium chloride raw material. The potassium chloride raw material is treated, prior to granulation, with at least one alkali metal carbonate and at least one phosphate additive selected from alkali metal monophosphates, alkali metal pyrophosphates, linear alkali metal polyphosphates and mixtures thereof, in the presence of water.

A method for producing potassium chloride granular materials from a crystalline potassium chloride raw material, wherein, before the granulation process, the potassium chloride raw material is treated with at least one alkali metal carbonate and at least one metaphosphate additive in the presence of water.

A method for producing potassium chloride granular materials from a crystalline potassium chloride raw material, wherein, before the granulation process, the potassium chloride raw material is treated with at least one alkali metal carbonate and at least one hydrogen phosphate additive in the presence of water. The alkali metal carbonate is anhydrous sodium carbonate, sodium carbonate monohydrate or sodium carbonate decahydrate.

A biological-laden dry fertilizer includes a dry fertilizer granule and a coating inoculated with a biological agent and applied to the dry fertilizer granule. The biological coating is a solution or suspension comprising water or oil and at least one biological agent, or an emulsion of an oil and a solution or suspension comprising water and at least one biological agent. The at least one biological agent is a biological chemical, plant extract, microbial agent, and/or a living organism.

A method for separating a particulate stream of an evaporite mineral feedstock, the method comprising passing the stream to an air classifier configured to separate the particulate stream into a fine component and a coarse component.

An aqueous composition comprises at least one oxidizable sulfur-based compound. A concentrated extract of the aqueous composition includes a gas chromatography/mass spectrometry-detectable amount of contaminating refinery hydrocarbons but the aqueous composition is free of refinery odor when stored for at least 24 hours at room temperature and 60% relative humidity. The aqueous compositions are prepared from a gas stream obtained from a petroleum refinery process, a coke oven, or the like, containing at least about 4 mol %, more specifically about 15 mol %, of hydrogen sulfide (H.sub.2S) and/or sulfur dioxide (SO.sub.2) and/or ammonia (NH.sub.3), and at least about 0.1 mol % of contaminating refinery hydrocarbons. The aqueous compositions are suitable for use in fertilizers, mining and industrial applications.

According to some embodiments of the present invention there is provided herein a compacted granule of Polyhalite, Potassium salt and an inorganic binder comprising a strength of 2.7 KgF/Granule when measured after production.
