Description

Effects of several herbicides on soil nitrification in volcanic ashes soil were examined by use of the soil perfusion technique.<br>The herbicides could be ranged in the following order of increasing effectiveness as inhibitors of oxidation of ammonia to nitrate: prometryne, lenacil<diphenamide, trifluralin<vernolate<MCPA<<swep, PCP.<br>PCP and swep were extremely inhibitory of nitrification, giving virtually complete inhibition in 215ppm or 200ppm, respectively. And these herbicides at their normal field rates could have a little inhibitory activity.<br>Nitrification proceeds by two successive steps, the oxidation of ammonia to nitrite and the subsequent oxidation of nitrite to nitrate. Inhibitory actions of swep was mainly on the process of NH4+→NO2-, and PCP was on the both process of NH4+→NO2- and NO2-→NO3-.
