ABSTRACT:
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.
