Solvent systems for the formulation of alkyl thiophosphoric triamide urease inhibitors, that provide stable dispersion of alkyl thiophosphoric triamides for even distribution (in low or high concentrations) onto fertilizers containing urea in liquid or solid form.

The invention relates to agriculture, and specifically to regulators of plant growth and development that can be used for the pre-sowing treatment of cereal crop seeds and are in the form of bis(oxymethyl)phosphinic acid and biogenic metal salts thereof with the general formula (I) Me.sup.n[OP(O)(CH.sub.2OH).sub.2].sub.1, where n may be 1 or 2 and Me may be any of the following: H, Na, Ca, Mg, Co, Cu, Zn, Mn. The claimed compounds of formula I are effective regulators of plant growth and development when acting in concentrations of 1.Math.10.sup.7-1.Math.10.sup.12%. Pre-sowing treatment of the seeds of cereal crops, namely wheat, corn and rice, by means of the claimed compounds increases germination energy and germination capacity up to 13%, also increases plant vigor, and rootlet and shoot lengths increase up to 36%. Crop harvests increase and the quality of the resulting grain improves, which expands the range of effective, environmentally friendly plant growth and development regulators that act at the level of natural phytohormones.

The present invention relates to the use of mixtures containing secondary calcium and secondary magnesium phosphonate for combatting harmful fungi, to the use thereof as fertilizer or plant nutrient, to a mixture, containing secondary calcium and secondary magnesium phosphonate in a specific molar ratio, characterized in that the solid form of the mixture has a water solubility of at most 5 g/l, and to a method for preparing a mixture containing secondary calcium phosphonate and secondary magnesium phosphonate.

A method for processing of municipal and industrial wastewater in waste activated sludge treatment (WAS) as configured to achieve enhanced biological phosphorus removal (EBPR), and include design elements that promote the development of aerobic granular sludge (AGS) with excellent settling properties, and may be incorporated into existing or new wastewater treatment systems. A WAS with polyphosphate accumulating organisms are transferred into a batch flow tank to release a soluble phosphorus under anaerobic conditions to promotes fermentation. The polyphosphate accumulating organisms within the WAS are transferred to a reactor vessel to release the soluble phosphorus and then to form a liquid supernatant and a settled WAS solids. The liquid supernatant is withdrawn and the settled WAS solids are retained within in the reactor vessel to ferment and form a liquid WAS phase over a settled WAS solids phase and release a soluble phosphorus component of the settled WAS solids into the liquid WAS phase, and then separate the liquid WAS phase enriched with the soluble phosphorus component from the settled WAS solids phase to create a phosphorus rich feedstock.
