A farmer was planting wheat crops in his field. He added nitrogen-rich fertiliser to the soil to get a good yield of crops. In the neighbouring field, another farmer was growing bean crops, but she preferred not to add nitrogen fertiliser to get healthy crops. Can you think of the reasons?

The bean crop farmer didn’t use nitrogen fertiliser because legumes like beans have root nodules that contain nitrogen-fixing bacteria. These bacteria naturally enrich the soil with nitrogen, reducing the need for additional fertilisers.

    1. The bean farmer avoided nitrogen fertiliser because legumes like beans have a natural advantage. Their roots contain nodules that host nitrogen-fixing bacteria. These microbes convert atmospheric nitrogen into forms usable by plants. This natural process provides enough nitrogen for healthy crop growth, unlike wheat, which lacks such bacteria and needs nitrogen fertilisers. Thus, legumes help in maintaining soil fertility without external inputs.
