A process for preparing an elemental sulphur-containing composition for use as a fertilizer and/or soil improver comprises wet milling elemental sulphur in a liquid to produce a micronized sulphur slurry for application to soil, and further comprises adding a preventive scavenging additive for fixating sulphur dioxide and hydrogen sulphide gases that are released downstream of the mill.

The present technology relates to a micronutrient fertilizer comprising immediate release and sustained release components contained within a hydrated polyelectrolyte solution. The fertilizer is readily dispersed and stable over long periods of time.

A method for inoculating a plant with a nitrogen-fixing bacteria such as Gluconacetobacter diazotrophicus, said method comprising administering the nitrogen-fixing bacteria to a wound of a growing plant, for example to recently cut grass. Inoculation in this manner leads to enhanced growth characteristics including increased greenness of grass. Novel compositions suitable for use in the method are also described and claimed, together with kits for producing these.

A plant (10) for treating poultry manure comprises:—an apparatus for the first treatment (11) of the poultry manure, configured to carry out dilution, homogenization and hot, damp alkaline hydrolysis of the diluted poultry manure and to supply at exit a stream of inert materials (18) and a stream of hydrolyzed poultry manure (19); —a second treatment unit (20) configured to carry out a flocculation of the stream of hydrolyzed poultry manure (19) and to supply a hydrolyzed and flocculated stream of poultry manure (22);—a solid-liquid separation unit (24) configured to separate the stream of hydrolyzed and flocculated poultry manure (22) into a solid fraction (26) suitable for anaerobic digestion and a liquid fraction (28);—a liquid post-treatment unit (30) of the liquid fraction (28) supplied by the solid-liquid separation unit (24) configured to recover water (32, 60), ammonium sulfate (31, 56) and salts (34, 54, 54a) from the liquid fraction (28).

Disclosed is a stable fertilizer composition including: a sulfur-containing compound; and a reaction product of a potassium-containing compound and a humectant selected from the group consisting of polyhydric alcohols, esters of polyhydric alcohols, polyalkylene glycols, and hydroxylated carboxylic acids. One version of the fertilizer composition also includes a nitrogen-containing compound; a phosphorous-containing compound; and at least one more additional macronutrient or micronutrient. The macronutrient may be selected from the group consisting of calcium and magnesium, and the micronutrient may be selected from the group consisting of zinc, manganese, iron, copper, calcium, magnesium, cobalt, boron, nickel, and molybdenum. The fertilizer composition may be essentially free of chelated metals and chelated metal salts. Methods of using a solution of the fertilizer composition for supplying plant nutrients to a plant are also disclosed.

A fertilizer including a growth enhancing component, in at least one example a co-polymer of fulvic acid and poly-metallic humates is present in the amount of from about 80% to about 90% by weight, based on a total weight of the fertilizer; a plurality of elements present in the amount of from about 3% to about 7% by weight, based on the total weight of the fertilizer; and one or more secondary nutrients, micronutrients, and biologically active heteromolecular trace-metal complexes present in the amount of from about 3% to about 10% by weight, based on the total weight of the fertilizer.

The present invention relates to a process, methods and materials for generating fertilizers from seawater resources, especially in conjunction with seawater desalination plants. Here, we demonstrate that varying compositions of fertilizers such as nitrogen/potassium, nitrogen/phosphorus/potassium, nitrogen/potassium/sulfur, and nitrogen/phosphorus/potassium/sulfur, potassium/sulfur, potassium along with micro and secondary nutrients can directly be generated as part of the extraction process to meet the requirements of both starter and sustained phases of plant growth.

The disclosure relates generally to a synthetic agricultural product and methods and systems for producing a synthetic agricultural product or composition. The method of producing a synthetic agricultural product may comprise providing an effective amount of fertilizer and/or other agricultural product sufficient to effectuate a response in a plant, an effective amount of a mineral substance having a high cation exchange capacity, and an effective amount of water sufficient to effectuate a desired result in a plant. The fertilizer and/or other agricultural product and mineral substance may be added into the effective amount of water, thereby creating the synthetic agricultural product. Known ions, such as fertilizer ions, and native ions in the native mineral substance may be exchanged to produce a synthetic agricultural product.
