Did you know that Broad beans "Fava beans" are one of the world’s most powerful nitrogen fixers?
Nitrogen fixation is the process by which nitrogen changes into an available and useful form source for the plant. Legume plants like broad beans draws nitrogen from the air and converts it into a form that can be stored in their roots, and this can be done with the help of nitrogen-fixing bacteria that live on their root nodules.
While the plant is growing, it holds the converted nitrogen in its roots. But as soon as the plant dies, it’s released into the soil, this nitrogen will be used by other plants. Nitrogen is essential for plant growth, so nitrogen fixers are hugely helpful to farmers and gardeners alike.
All plants need nitrogen to grow successfully. They use it to manufacture amino acids, proteins, nucleic acids and other components necessary for life. Without nitrogen, they can’t survive, and because of its critical role in plant health and growth, gardeners often add nitrogen to the soil in the form of artificial fertiliser.
Not only broad beans enrich the soil, they also eliminate the need for artificial fertiliser, making them a hugely sustainable crop to grow!
