Calcium cyanamide fertilizer with triazone

Abstract

The present invention is a liquid fertilizer comprising a calcium cyanamide component that is dissolved, co-applied, dispersed, or suspended in a solution of aqueous triazone urea. The combination of calcium cyanamide and triazone urea produces a slow release of nitrogen that requires fewer reapplications and is more effective than heretofore fertilizers. In one preferred embodiment, the fertilizer or plant treatment is further combined with a soil treatment including polycarboxylate acids and polyaliphatic acid salts in combination with potash to further enhance the properties of the fertilizer.

Claims

1. A nitrogen releasing liquid fertilizer, comprising: aqueous triazone urea solution; solid calcium cyanamide; and potash: wherein the solid calcium cyanamide makes up between 1-25% by weight in the triazone urea solution.

2. The nitrogen releasing liquid fertilizer of claim 1, further comprising a soil treatment including polycarboxylate acids.

3. The nitrogen releasing liquid fertilizer of claim 1, further comprising polyaliphatic acid salts.

Description

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(1) Urea-triazone nitrogen is a stable solution resulting from a controlled reaction in aqueous medium of urea, formaldehyde, and ammonia which contains at least 25% total nitrogen. This nitrogen source contains no more than 40%, nor less than 5%, of total nitrogen from unreacted urea and not less than 40% from triazone. All other nitrogen shall be derived from water-soluble dissolved reaction products of the above reactants. It is a source of slowly released nitrogen that is a safer and more effective material for direct application on plant foliage. In an experimental trial, tomato plant growth was enhanced with foliar application of urea-triazone relative to that obtained from ammonium nitrate or urea. The stability of this nitrogen source from potential losses via ammonia volatilization and nitrate leaching when soil applied was also verified by the results of the experimental field trials.

(2) Calcium Cyanamide is a chemical compound that has previously been used in industrial agricultural fertilizers to help plants reach high yields, thus maximizing profits for farmers. The substance is typically applied directly to the soil, where it breaks down into ingredients that are beneficial to plan growth. Calcium cyanamide also functions in other facets in addition to being a fertilizer. Calcium cyanamide's primary function is that of a fertilizer in industrial agriculture settings. The chemical enriches the soil with beneficial lime and, upon coming into contact with water, begins to break down, releasing nitrogen into the soil by way of ammonia. In addition to acting as a fertilizer, the chemical also functions as an effective pesticide and fungicide by killing insects, soil parasites and harmful fungi. The chemical works as an defoliant and herbicide by preventing weed germination as well.

(3) The present invention combines aqueous triazone with solid calcium cyanamide to yield a liquid fertilizer that can be added directly to the soil for slow release of available nitrogen. Potash, an impure combination of potassium carbonate and potassium salt, can be added to the triazone/calcium cyanamide composition in a preferred embodiment to produce an even more stable and effective liquid fertilizer.

(4) In one preferred embodiment, the calcium cyanamide makes up between 1-25% by weight in the triazone urea solution. Beginning with between 5 and 60 gallons of triazone, calcium cyanamide is added in the range of 0.5 pound to 30 pounds and mixed thoroughly through agitation or other mechanical mixing. This fertilizer can be supplemented with approximately one gallon of potash per acre.

(5) The composition can further be enhanced by incorporating certain plant growth regulators to improve functionality. One such plant growth regulator is IBA Indole-3-butyric Acid (IBA) CAS 133-32-4. This as well as other plant growth hormones (NAA, 6ba, CPPU) increase the effectiveness of the fertilizer and adds efficacy to the triazone and cyanamide as a starter fertilizer. Additionally, adding carbon (granular or powder) or having the option to add more carbon-based sources such as biochar can enhance the efficacy. Currently cyanamide has graphite as a source however there is a pressing issue in agriculture to add biochar and other carbon based elements back into soil during fertilizer application.
