摘要：

Very few compounds have been shown to possess both urease and nitrification inhibitor activity. The ability to control both of these processes by the addition of a single additive is, however, highly desirable. During our work with the urease inhibitor thiophosphoryl triamide (TPTA) we have discovered that this material affects inhibition of urea hydrolysis by urease and ammonium oxidation by nitrifiers. This discovery suggests the pursuit of a new class of agrochemical compounds which can be designated as ammonium/nitrate ratio control agents because of their potential ability to provide controllable levels of ammonium and nitrate to cro in systems.
