Nitrification inhibitors at a glance: A number of compounds like dicyandiamide (DCD), nitrapyrin and 3,4-dimethylpyrazole phosphate (DMPP) have been reported to inhibit the nitrification process in soils (Zerulla et al.
These differences are attributed to the effects of zinc in the coating and the effectiveness of the dicyandiamide catalysts.
In recent decades, dicyandiamide (DCD) has been used extensively as a nitrification inhibitor (NI) because of its highly effective inhibition of nitrification, and its non-volatile and non-biocidal nature (Trenkel 1997).
In this new method, GUP is synthesized by the complete reaction of dicyandiamide, phosphoric acid, and water at a reaction temperature between about 90[degrees]C and 120[degrees]C, whereas prior to reaction, the mole ratio of dicyandiamide to phosphoric acid is 1.
When the laminate is heated, dicyandiamide can interact with copper causing adhesion loss.
