North Dakota State University (NDSU) researchers are investigating how microbial communities interact within agricultural environments to understand their effects on soil health and crop productivity. Assistant Professor Samiran Banerjee is leading research focused on understanding the factors that influence microbiome development, stability, and resilience.
Microbiomes are communities of microorganisms that contribute to important agricultural processes, including nutrient cycling, carbon dynamics, and plant growth. Banerjee's research examines how these communities form, interact, and respond to environmental conditions using microbial ecology, biological analysis, experimental methods, and computational modeling.
A major part of the research involves the North Dakota Agricultural Microbiome Project, a statewide initiative focused on understanding microorganisms that contribute to soil health. Banerjee's research team has collaborated with more than 100 North Dakota farmers and Extension personnel across all seven NDSU Research Extension Centers, collecting more than 3,000 soil, root, grain, and groundwater samples.
These samples help researchers study microbial communities across different soil types, crops, farming practices, and climatic conditions. The diverse agricultural landscape of North Dakota also provides opportunities to examine microbiome behavior across multiple locations and environmental settings.
The research team is identifying microbial keystone taxa, which are microorganisms that play particularly important roles in maintaining the structure and functioning of microbial communities. By studying their positions within microbial networks, researchers aim to determine which organisms have consistent ecological importance across different agricultural environments.
The team uses DNA sequencing, multi-omics analysis, microbial culturing, molecular biology, and machine learning to investigate microbial interactions. Controlled experiments using synthetic microbial communities also help researchers understand how removing specific microorganisms affects the stability and performance of these communities.
The findings could provide farmers with better information about maintaining healthy soils, improving fertilizer-use efficiency, and strengthening agricultural resilience. Understanding how soil properties, crop management, and microorganisms interact may also support more effective and sustainable farming practices.
Banerjee's upcoming research will connect statewide field observations with additional controlled experiments and computational models. The team aims to understand how microbial interactions influence microbiome stability and plant resilience across different agricultural and environmental conditions.
Through this research, North Dakota State University aims to improve the understanding of agricultural microbiomes and develop more reliable approaches to soil management and long-term crop productivity.
