Abstract Background Nanofertilisers can enhance the efficiency of nutrient utilization in crop production. Nevertheless, it is unclear how soil microbial and enzyme activities are affected by the application of nanofertilisers to wheat inter‐root soil. Aims The study aims to investigate the influences of nanocarbon (NC) and nano‐calcium carbonate (NCC) on soil enzyme activities and microbial community in the open field setting. Methods The effects of nanofertilisers on soil wheat rhizosphere soil were studied through the evaluation of soil microbial quantity, enzyme activity, and microbial diversity. Results The findings revealed that the combined utilization of nanofertilizers and compound fertilizers (CF) led to an augmentation in the diversity of the soil microbial community. When comparing the effects of 100% composite nanofertilizers (100% CF + 50% NC + 50% NCC) with the control (CK) (100% CF), it was observed that the activities of urease (EC 3.5.1.5), catalase (EC 1.11.1.6), alkaline phosphatase (EC 3.1.3.1), sucrase (EC.3.2.1.26), as well as the number of fungi, actinomycetes, and bacteria, increased by 22.4%, 7.7%, 17.8%, 9.3%, 35.9%, 27.7%, and 26.0%, respectively. Similarly, the employment of 70% composite nanofertilizers (70% CF + 35% NC + 35% NCC) also resulted in an enhancement of these aforementioned indicators. The magnitude of increase over the 100% CF was 19.0%, 6.6%, 13.6%, 6.2%, 26.8%, 21.3%, and 23.5%, respectively. Notably, there was no significant diffe...
