Reduction of nitrogen losses in agriculture by fertilizer additives: Appeal for more detailed scientific work—Comments on Guo et al. “Efficacy of four nitrification inhibitors for the mitigation of nitrous oxide emissions under different soil temperature and moisture,” Journal of Plant Nutrition and Soil Science (2022), 185(1), 60–68

In Guo et al. (2022), the difference between pure nitrification inhibitors (NI), fertilizers treated with NI, and formulations containing NI was insufficiently considered. Presented results are misleading and inappropriate to evaluate the efficiency of an NI application by pure NI as well as NI‐treated products such as ENTEC® 26 and PIADIN®, in particular with respect to practical field conditions.
