What Are The Common Urinary Enzyme Inhibitors?

According to experts, urease, also known as urea hydrolase, is a type of nickel-containing (Ni) metalloenzyme secreted by many soil microorganisms. Its main function is to promote the decomposition of urea. Under the participation of water, urea is decomposed into ammonium carbonate, which is then dissociated into ammonia (NH3) and carbonic acid. Ammonium can be adsorbed by soil without being easily lost, and can be absorbed and utilized by crop roots. However, in the case where a large amount of urea is applied and the crop cannot be absorbed or utilized in time or exceeds the soil holding capacity, excessive free ammonia may cause loss of volatilization or the like. Moreover, ammonia is further nitrated into nitrate nitrogen in the soil. The characteristics of nitrate nitrogen are that it can not be preserved by soil preservation and may be denitrified under weather conditions to form a gaseous loss. Therefore, when using a single urea or urea-based compound fertilizer for surface application or large-scale application, in order to prolong the fertilizer efficiency period and avoid the loss of a large amount of free ammonia accumulation, a urease inhibitor may be added to the urea.

Common urease inhibitors: hydroquinone, phenylmercury acetate, copper sulfate, o-phenylphosphoryl diamine (PPD), catechol, thiophosphoric triamide (NBPT) and the like.
