Fertiliser prices and shortages are hamstringing our farmers. But we have other options
Compost, manure and food waste can be turned into biofertilisers made from natural materials.
Nitrogen fertilisers are crucial for feeding the world's population. However, recent disruptions have led to increased prices and supply challenges. Nitrogen fertiliser production relies on natural gas, which has become more expensive due to global conflicts and geopolitical tensions. Farmers are now facing higher costs, which ultimately impact the prices of everyday food items.
Biofertilisers, made from organic materials, show promise as a more sustainable alternative. However, they are less concentrated in nitrogen and may not work under all conditions. Further research is needed to fully understand the potential and limitations of biofertilisers, ensuring they can effectively support farmers while protecting the environment.
