This is the reason for the recognized long-lasting and uniform nitrogen effect of calcium cyanamide. Therefore it is mistaken to aim for a strongly ammonium-based nutrition of plants by applying a fertilizer that has a high ammonium content. Functional Chemicals; Product Summary. Using it during cultivation would risk damaging the plants. for the preparation of cyanogen melt and cyanide and dicyandiamide, melamine; for the manufacturing of nitrogenous fertilizer, pesticide carbendazim; as metal heat treatment agent . According to the U.S. Environmental Protection Agency, commercially available calcium cyanamide preparations appear as a lumpy powder that is dark gray to black in color. So it is a naturally occurring compound. The lime (calcium carbonate) content is so small that it cannot counter the acidifying effect of the nitrogen, so CAN has a slight acidifying effect on the soil. It is not typically used in home gardens. Below I try to give some more information on this product. By contrast, calcium cyanamide contains nitrogen (19.8%) almost exclusively in the form of a calcium cyanamide bond, and the nitrogen is chemically bonded to the lime. As soon as calcium cyanamide comes into contact with soil moisture, the calcium cyanamide dissolves from the fertilizer grain and decomposes immediately into calcium hydroxide and cyanamide. The highly effective lime in calcium cyanamide improves soil structure, prevents silting and allows rainwater to seep in more quickly. 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. Calcium Cyanamide is a chemical compound used in industrial agricultural fertilizers. 10 days), during which phase the calcium cyanamide in the soil works to counteract the eggs and larvae of pasture parasites. What Is Curling;How To Play Curling On Ice? At the same time the cyanamide phase also has a certain counteractive effect on freshly germinated weeds and rosette plants such as dandelions. This hygiene effect ensures healthier pastures: No other fertilizer can achieve this effect! These forms of nitrogen have different effects. But with calcium cyanamide the further conversion to nitrate is then greatly delayed because the fertilizer inhibits nitrate-forming bacteria in the soil. This exothermic reaction then proceeds spontaneously once it has been triggered. This process proceeds very rapidly even at low temperatures: with adequate moisture and good soil contact for the fertilizer granules - by working in the fertilizer to a shallow depth, for example – practically all of the nitrogen is available as cyanamide in the soil solution after just one day! Under natural conditions most of the ammonium is converted by soil bacteria into nitrate (nitrification), and in doing so becomes effective.

The interaction of cyanamide with alcohol is well-known. This is because a small part of the cyanamide in the soil is initially converted into dicyandiamide (DCD). Manufacturing of the fertilizer usage begins in 1936 that will be hit next year of establishment, and sales as agricultural chemicals begin in 1957. Environmental Protection Agency: Calcium Cyanamide, Centers for Disease Control: Calcium Cyanamide. What is important is the carbamide nitrogen as contained in urea, or the ammonium and the nitrate nitrogen as contained in calcium ammonium nitrate. Unintentional absorption of cyanamide can therefore take place only through the inhalation of dust or prolonged contamination through the skin. As new microbiological studies show, the soil microflora is only temporarily impaired by using  calcium cyanamide:  even at extremely high application rates the microbial populations exceed their initial levels after only few days. To give you a summary answer: calcium cyanamide is a chemical that is not allowed in organic farming . Calcium cyanamide is the inorganic compound with the formula CaCN 2. Remains of the fertilizer granules which you can still see lying on the soil are the lime and carbon portion of the fertilizer. Applications. Nitrate moves freely in the soil. This process happens relatively speedily, and depending on the soil temperature takes between 1 to 4 days.
