Studying microbes in cropping systems is vital for improving agricultural sustainability and productivity. Microbial communities in soil and around plant roots influence nutrient cycling, enhance plant growth, and suppress diseases. Beneficial microbes can reduce the need for chemical fertilizers and pesticides, lowering environmental impact and production costs. Understanding these interactions helps farmers manage soil health, boost crop resilience to stress, and adapt to climate change. Research also supports the development of microbial-based products, such as biofertilizers and biopesticides. Overall, studying microbes in cropping systems enables more efficient, eco-friendly farming practices and contributes to global food security.
