The invention relates to (thio) phosphoryl triamides of the general formula (I) and to methods for producing them and to their use as an agent for regulating and/or inhibiting the enzymatic urea hydrolysis. The invention also relates to fertilizers that contain said compounds. The inventive (thio) phosphoryl triamides represent extremely effective urease inhibitors that have an excellent hydrolytic resistance and that can be produced at low costs and with little technical effort.
摘要:
The invention concerns a method for the production of nitrate containing products (fertilizers, technical products) from undercooling melts, wherein a XN - water solution is evaporated up to a content of 50-99.8 weight % XN, where X is one or more selected from Ca, Mg, NH4, Na and K, and N means nitrate. The preferred range of XN is 70-99.5 weight %. The melt is cooled down to and kept at a temperature at or below the crystallisation point and finely divided solid XN powder consisting of the equilibrium phases is added to the melt. Melt drops are then formed and allowed to cool and solidify during up to 70 seconds. It is preferred to use a cooling belt for solidification of the particles. The belt is cooled by air, water, oil or another medium.

Processes and structures for using calcium cyanamide fertilizer in a manner to greatly enhance its most effective soil treatment form prior to its application. Calcium cyanamide transformation structures have both fertilizing and pesticidal qualities; however, it is difficult to obtain uniform, efficient effectiveness from dry calcium cyanamide's liquid transformation structures. In the process of this invention, dry, dusty granules and fines of calcium cyanamide are placed directly into tanks of liquid for transformation or within biodegradable bags through which water can freely flow. The bags are submerged in a tank of water. The insoluble calcium and carbon components thereof remain as solid residuals within the bags. Hydrolysis occurs and the solution is biocidal and ready for immediate application. The solution can be sprayed or irrigated onto a targeted soil area with conventional dispersal equipment. The remaining non-dissolved material in the bags can be dispersed on and into the plant crop soil. Additives of other fertilizers into the above solution can be used to enhance effectiveness. When the calcium cyanamide is placed directly into the liquid, the mixture will become slurry-like. In the processes herein, when the solids of calcium cyanamide are not isolated during hydrolysis, the slurry mixture is utilized in recent modern specialized solids fertilizer suspension dispersed equipment having sufficient agitation to keep the solids in suspension.

Calcium cyanamide compositions and methods for their use are disclosed. The compositions and methods stabilize active ionic compositions comprising calcium cyanamide and enhance the effectiveness of calcium cyanamide alone or synergistically in combination with nitrogen containing materials such as urea and organics, for example, manures. The compositions and methods also facilitate controllable site directed delivery of the contents of the stabilized compositions. The compositions and methods are effective for fertilizing, soil amending, metal stabilizing and odor and organism inhibition. The compositions are stable, easily calibrated, and non-clogging for spray delivery to target sites.

摘要:
Dicyandiamid wird auf die Oberflächen von ammonium- und sulfatgruppenhaltigen Düngemitteln bei einer Temperatur des Düngemittels von 6O bis 13O °C durch Vermischen mit feinteiligem Dicyandiamid aufgebracht. Gleichzeitig oder unmittelbar anschließend wird eine Calciumnitrat enthaltende wäßrige Lösung unter weiterem Vermischen aufgebracht.
