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.

The invention relates to a mechanochemical process for decontaminating and/or for eliminating problematic, synthetic, biogenic and biological materials A; for breaking down phosphates B; for immobilising metals and the compounds C thereof; for separating carbon dioxide and carbon monoxide D into elements; and for recovering valuable products E. The process comprises: —providing a material F to be milled containing —at least one material A, B, C and/or D and —at least one type of carbon or carbon-yielding material G, or alternatively providing the components of F and G separately from one another; —filling the material F to be milled into a mechanical mill (1), or alternatively —filling the components of the material F to be milled into a mechanical mill (1) and —milling by means of milling elements (1.2) moved by agitation means (1.4) or by means of rollers (1.4.6); after which —the resulting product I is separated from the milling elements (1.2) or the rollers (1.4.6) and is discharged from the milling chamber (1.1) and worked up. The invention also relates to the use of the products I as valuable materials E, the use of a self-cooling electric motor (4) for driving a mechanochemical mill (1), and mechanochemical mills (1) having new agitation means (1.4).

A coating is applied in one or more layers on a granular material, such as a granular fertilizer material or the like. The coating may include a diisocyanate in either pure form or partially polymerized form, a polyol or polyol mix, and optionally a wax. The polyol or polyol mix may be, for example, a polyester polyol, a polyether polyol, or combinations thereof. In some examples, the polyol or polyol mix may be an aliphatic glycerine initiated polyether polyol, an aliphatic amine initiated trifunctional polyol, castor oil or castor oil derivative, or ethylene diamine that has been propoxylated or ethoxylated, and combinations thereof. The coating is reacted on the granular material.

Systems and methods for producing nitrates, nitric acid, salts thereof, or a mixture thereof are disclosed. The systems may include a feed conduit configured for receiving a feed stream comprising molecular oxygen and molecular nitrogen; an inlet conduit configured for receiving an inlet stream; a plasma reactor fluidically coupled to the inlet conduit, the plasma reactor fluidically coupled to a reactor-outlet conduit configured for receiving the reactor-outlet stream, the plasma reactor configured to produce oxidized nitrogen species; and an absorber fluidically coupled to the reactor-outlet conduit, the absorber configured to receive the reactor outlet stream and to produce nitrates, nitrites, nitric acid, salts thereof, or a mixture thereof from the reactor outlet stream. A recycle conduit may be fluidically coupled to the absorber and the inlet conduit, wherein the recycle conduit is configured to receive the gas-phase stream from the absorber and provide the gas-phase stream to the inlet conduit.

A method for capturing material extracted from biochar is provided comprising the steps of: (i) providing a biochar; (ii) contacting the biochar with an extraction media, where the extraction media causes the removal of residual compounds from the pores and surface of the biochar, creating a resulting extract comprised of the extraction media and removed compounds; and (iii) collecting the resulting extract. The method also can include other steps of extraction and purification. The method further comprises the step of applying the resulting extract to seeds, plants, soil, other agricultural products, or for use in other applications. A biochar having high levels of soluble signaling compounds is also provided, where the biochar is derived from a biomass source that together with predefined pyrolysis parameters produces resulting biochar having increased levels of soluble signaling compounds that are known to increase seed germination rates and early plant growth.

Disclosed herein are methods of increasing nitrogen fixation in a non-leguminous plant. The methods can comprise exposing the plant to a plurality of bacteria. Each member of the plurality comprises one or more genetic variations introduced into one or more genes or non-coding polynucleotides of the bacteria's nitrogen fixation or assimilation genetic regulatory network, such that the bacteria are capable of fixing atmospheric nitrogen in the presence of exogenous nitrogen. The bacteria are not intergeneric microorganisms. Additionally, the bacteria, in planta, produce 1% or more of the fixed nitrogen in the plant.

Utilization of nitrogen oxides contained in the ambient air including a system and a method with which the nitrogen oxides can be utilized for the production of liquid or solid chemicals.

An agricultural paper mulch sheet including a paper based substrate and a nutrient additive. The nutrient additive may be a water soluble nitrogen fertilizer. The agricultural paper may be deployed from rolls and draped over crops in a garden or field, wherein the agricultural paper covers a substantial portion of the soil in which the plants will grow or are growing, while, in some preferred embodiments, providing openings (i.e., holes) for individual plants to emanate from the soil through the agricultural paper set forth around the plant. The sheet is preferably porous, tillable, and biodegradable. The substrate may have an ink pattern printed on it. The method includes applying the nutrient additive to the substrate preferably via a printing process.
