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.

A NO.sub.x and SO.sub.x oxidation with atmospheric oxygen to remove NO.sub.x and SO.sub.x from flue gases. The combined system for catalytic oxidation and wet-scrubbing of NO.sub.x and SO.sub.x from a flue gas and manufacturing fertilizers includes: an air separation unit for separating atmospheric oxygen from air and producing an air stream enriched with atmospheric oxygen, an adsorption and oxidation reactor containing an oxidation catalyst and carrying out the catalytic oxidation of NO.sub.x and SO.sub.x by said oxygen to yield nitric and sulphuric acids, a separator and reactor control unit for separation of products and liquids and controlling the reaction; and a vessel containing ammonia streaming said ammonia into the reactor or into the control unit to react with the nitric and sulphuric acids and to yield the fertilizers.

The present invention discloses a method for safe production of rice on soil mildly and moderately polluted by heavy metals. The method includes applying a passivator before transplanting rice seedlings to reduce activity of heavy metals in soil, and then spraying a foliar barrier from the peak tillering stage to the booting stage of rice and at the filling stage of rice; the passivator includes bentonite, gypsum powder, lime, a biochar, an iron-based biochar, a slow-release iron-based biochar, an iron-sulfur-silicon composite biochar, a heavy metal cadmium passivator and a cadmium-arsenic synchronous passivator for activating sulfur reducing bacteria in paddy soil; and the foliar barrier includes an acid silica sol, a selenium-silicon composite sol, a cerium composite silica sol, a ferrous modified selenium sol. The method can also include applying a nitrate nitrogen fertilizer at the seedling stage of rice, and/or applying a phosphorus potassium fertilizer at the tillering stage of rice.
