Agronomic practices-driven response of nitrogen-related microorganisms

Background

The significant variability in agricultural ecosystems leads to considerable differences in soil microbial community responses to nitrogen, attributed to the diverse combinations of agronomic practices, such as planting patterns and fertilization strategies.

Results

There is no doubt that reducing nitrogen fertilizer inputs is a crucial step in minimizing greenhouse gas emissions; however, determining the optimal nitrogen fertilizer inputs for different ecosystems, while maintaining crop yields, remains a significant challenge. The observed differences in microbial community responses to nitrogen appear to provide targeted insights in this regard. We systematically review and discuss the variances in soil microbial responses to nitrogen across different agricultural systems, aiming to assist researchers and farm managers in providing focused references for scaling up agricultural systems.

Conclusion

From a practical standpoint, targeted support for nitrogen management in various agricultural ecosystems is essential to reduce nitrogen waste, maintain soil health, and curb global warming trends. These factors are closely linked to crop types, management practices, and the local environmental conditions of the agricultural systems. Furthermore, the rational utilization of M genes to assist in regulating the assembly of soil nitrogen, cycling-related microbial communities may serve as an effective approach to achieving precision agriculture and promoting ecosystem sustainability.
