Nitrous Oxide Emission Reduction in Agriculture

Detailed overview of innovation with sample startups and prominent university research


What it is

Nitrous oxide (N2O) emission reduction in agriculture focuses on mitigating the release of this potent greenhouse gas from agricultural practices. N2O is nearly 300 times more potent than carbon dioxide (CO2) in terms of global warming potential and contributes significantly to climate change. Agriculture is a major source of N2O emissions, primarily from nitrogen-based fertilizers and animal manure management. Addressing these emissions is crucial for building a more sustainable and climate-friendly food system.

Impact on climate action

By implementing advanced techniques in agriculture, like improved soil management and precision fertilization, the innovation significantly decreases nitrous oxide emissions. This reduces the overall carbon footprint of agriculture, contributing to global efforts in combating climate change by addressing a potent greenhouse gas, thus fostering more sustainable farming practices.

Underlying
Technology

Nitrous oxide emission reduction strategies in agriculture revolve around managing nitrogen inputs and optimizing farming practices:

  • Precision Fertilizer Management: Applying nitrogen fertilizers at the right time, in the right amount, and using the right placement methods can minimize nitrogen losses to the environment and reduce N2O emissions.
  • Nitrification Inhibitors: These chemicals slow down the conversion of ammonium to nitrate in the soil, a process that releases N2O.
  • Controlled-Release Fertilizers: These fertilizers release nitrogen gradually over time, matching crop nutrient needs and reducing nitrogen losses.
  • Improved Manure Management: Practices like anaerobic digestion and composting can reduce N2O emissions from manure storage and application.
  • Cover Crops and Crop Rotation: Planting cover crops and rotating crops can enhance soil health and reduce the need for synthetic nitrogen fertilizers, indirectly lowering N2O emissions.
