The adoption of biofertilizers represents a significant step towards climate-neutral agriculture, offering substantial potential for reducing greenhouse gas emissions and mitigating the environmental impact of conventional farming practices. Biofertilizers, which are composed of living microorganisms, contribute to improved soil health and plant nutrition while simultaneously addressing climate change concerns.

One of the primary climate benefits of biofertilizers is their ability to reduce reliance on synthetic nitrogen fertilizers. The production of synthetic fertilizers is energy-intensive and contributes significantly to agricultural greenhouse gas emissions. By contrast, biofertilizers, such as nitrogen-fixing bacteria, can provide plants with essential nutrients through natural processes, thereby reducing the need for synthetic inputs and associated emissions.

Furthermore, biofertilizers enhance soil carbon sequestration. By promoting the growth of beneficial microorganisms in the soil, these products contribute to increased organic matter content and improved soil structure. This not only leads to better water retention and nutrient cycling but also helps to lock carbon in the soil, effectively removing it from the atmosphere and contributing to climate change mitigation.

The use of biofertilizers also has indirect climate benefits through improved crop resilience.
