Secrets of soil-enriching pulses could transform future of sustainable agriculture

From lentils to chickpeas, and even the humble baked bean, pulses are perhaps best known as an alternative, plant-based source of protein. These plants are environmental heroes: they work together with soil microbes to “fix” nitrogen from the air, enriching the soil with nutrients to allow them to thrive. As their nitrogen-fixing capacity is becoming better understood, scientists are hoping to find ways to increase productivity, and eventually apply some of these effective soil-enriching characteristics to other crops such as cereals. With the ability to fix nitrogen, crops would need less nitrogen fertiliser and soil health would simu......
