The invention relates to a method and apparatus for in situ production of liquid nitrogen fertilizer and plasma activated water for agricultural nutrient management and irrigation water treatment. In the invention, there are two different kinds of plasma reactors operates in tandem.

A method of producing a fertiliser composition, the method comprising: (a) providing partially decomposed organic matter; (b) contacting the organic matter with: (i) an anaerobic digestate; (ii) a source of nitrate ion; (iii) a source of ammonia; and (c) contacting the mixture obtained in step (b) with a source of carbon dioxid. Also claimed is a fertiliser composition comprising partially decomposed organic matter admixed with an anaerobic digestate, a source of nitrate ion, a source of ammonia and carbon dioxide.

A method of producing a fertiliser composition, the method comprising: (a) providing a composition comprising an amino compound; (b) contacting the composition provided in step (a) with a composition comprising carbon dioxide; and (c) adding a composition comprising cellulosic fibres to the mixture obtained in step (b).

The present disclosure concerns a method for producing fertilizer particles comprising an alternative source of boron. It is found that certain colemanite and ulexite powders can be supplied to a fertilizer melt shortly before granulation essentially without dissolving into the melt. Accordingly, the fertilizer particles produced from the melt may contain negligible amounts or non-detectable levels of sodium borates or boric acid. Furthermore, the fertilizer particles can be homogeneous which is desirable for boron supplying fertilizers. It is also found that the fertilizer particles can supply boron to plants at a rate comparable to borax pentahydrate.

The present invention provides a method for reducing plant water stress which comprises contacting plants with dry milled fibre, particularly wheat fibre and pea fibre. Said contacting is carried out in a manner selected from the group consisting of coating seeds with a mixture comprising dry milled fibre, pelletizing seeds with a mixture comprising dry milled fibre, applying a mixture comprising dry milled fibre in the form of granules, and applying a mixture comprising dry milled fibre in the form of tablets. Prior to said contacting, dry milled fibre is admixed with soil for plants, and the resulting mixture may optional comprise further additives such as fillers, binders, inert powders, colouring agents, fertilizers, fungicides, growth hormones, or microorganisms for inoculation.

The present invention provides for methods of and compositions for enhancing microbial conversion of nitrate into ammonium. The methods and compositions alter the end products of microbial nitrate reduction to improve agricultural efficiency and lead to more sustainable and economically profitable agricultural practices.
