Nitrification increases soil fertility and a higher rate of grain production in cereal and leguminous crops. However, differential response of the nitrifying microbes and net nitrification rates (NNRs) of chemical fertilizers in cereals and leguminous crop soils of Bangladesh are unknown. Hence, the current research was undertaken to find out the differential response of the nitrifying microbes and NNRs of chemical fertilizers in some cereals ( Triticum aestivum and Zea mays ) and leguminous crops ( Lins esculenta , Pisum sativum , and Cicer arietinum ) soils. The NNRs and occurrence of ammonia-oxidizing archaea (AOA)/ammonia-oxidizing bacteria (AOB), and nitrite-oxidizing bacteria (NOB) were enumerated by mass spectrophotometer and q- PCR, respectively. The ranges of NNRs were 2.84±0.41 to 12.86±1.09 mg kg −1 h −1 and significantly higher ( p
