WebAfter three weeks of acclimation at pH 6.6, the rate of nitrification was approximately 85 percent of the maximum rate observed. Borchardt (1) performed a short term pH-nitrification study utilizing a 0.6 meter pilot RBC treating domestic wastewater effluent from a trickling filter in a laboratory where ammonia, alkalinity and pH were controlled. Nitrification inhibitors are chemical compounds that slow the nitrification of ammonia, ammonium-containing, or urea-containing fertilizers, which are applied to soil as fertilizers. These inhibitors can help reduce losses of nitrogen in soil that would otherwise be used by crops. Nitrification inhibitors are used widely, being added to approximately 50% of the fall-applied anhydrous ammoni…

WebFor Andosol, nitrification was the major contributor of N2O emissions regardless to the sampling timings and to the fertilizer types. Consequently, the efficiency of coated urea in terms of N2O mitigation depended on the soil type and the magnitude of the enhancement of soil processes (nitrification and denitrification) determined this efficiency.
