A use of 1,9-decanediol in retarding urea hydrolysis in soil is provided. It is found that 1,9-decanediol has a dual regulatory effect, which can not only inhibit the nitrification process, but also retard urea hydrolysis and reduce the transformation of urea to other nitrogen forms. As a fat-soluble root exudate, 1,9-decanediol has high stability in soil, is not easy to be leached away, and causes less environmental pollution. It further broadens an application field of 1,9-decanediol and improves an industrial value of 1,9-decanediol.

The present disclosure belongs to the technical field of ecological environmental protection, resource development and utilization and new materials, and particularly relates to a method and device for rapidly forming artificial clay and artificial organic ecological mud. The method comprises the following steps: raw material and water storage preparation; preparing nutrient aqueous solution; preparing mineral muddy water; preparing flocculent mineral solution; and reacting and dehydrating to form artificial clay or artificial organic ecological mud. The device comprises a grinding mill, a feeding system, a silo, a belt conveyor, an agitator, a dehydration system and a reservoir. In accordance with the present disclosure, the formation period of natural clay is greatly shortened by artificial means, making the clay become a renewable resource.

The present disclosure is related to a solid, particulate urea ammonium sulfate-based composition, the particles comprising a core comprising urea ammonium sulfate, and a coating layer surrounding and contacting the core, comprising from about 95 weight % to about 99.9 weight % of urea and a urease inhibitor. The composition displays a higher stability of the urease inhibitor. The present disclosure also provides a method to manufacture the solid, particulate urea ammonium sulfate-based composition.

The invention relates to a composition formulated to produce improved budbreak, flowering and disease resistance in perennial fruit crops and/or ornamental trees, comprising: (a) one or more compounds represented by the structure: in which R′ is OH or OCOCH.sub.3, and R″ is H, a monovalent cation, any C1-C10 alkyl group (saturated, unsaturated, linear or branched), any C7-C10 alkaryl group, or a phenyl group; and (b) an alkoxylated amine represented by the structure: in which A is selected from N, N.sup.1R.sub.1, or N.fwdarw.O, and wherein R.sub.1 is H, methyl or benzyl, R.sub.2 is any C8-C22 alkyl group (saturated, unsaturated, linear or branched), R.sub.3 is any C2-C4 alkyl group (linear or branched), x is in the range of 0 to 4 and y+z is in the range of 2 to 50. A method of use is also included, as is a method for preparing the composition.
