How can pulse crops be useful for soil?
Answer and explanation
Correct answer: They improve soil fertility by increasing nitrogen content
Pulse crops have Rhizobium bacteria in their root nodules. These bacteria help fix atmospheric nitrogen into forms useful for the soil, improving soil fertility and benefiting subsequent crops. Pulses do not normally remove all soil moisture or increase the sand content. Exam tip: associate pulses with nitrogen fixation and crop rotation.
