Which crop is most effective for nitrogen fixation in soil?
Wheat
Rice
Soybean
Maize
Soybean
Soybean is a leguminous crop that forms a symbiotic relationship with Rhizobium bacteria residing in its root nodules. These bacteria convert atmospheric nitrogen into ammonia, which the plant utilizes for growth and which enriches the soil's nitrogen content for subsequent crops.

Nitrogen fixation is a critical biological process in soil chemistry and sustainable agriculture, forming the basis of the Nitrogen Cycle taught in UPSC and State PSC Geography sections.
Leguminous plants like soybean are essential for crop rotation to reduce reliance on chemical urea fertilizers.
Rhizobium bacteria are the primary nitrogen-fixing microorganisms found in legume root nodules.
Soybean is globally recognized as one of the most efficient nitrogen-fixing oilseeds.
Nitrogen fixation increases soil fertility, making it a sustainable practice for soil health conservation.
Wheat, Rice, and Maize are cereal crops and are non-leguminous; they typically deplete soil nitrogen rather than fixing it.
Option A, B, and D are Cereal crops that require nitrogen-based fertilizers for optimal yield rather than contributing nitrogen back to the soil.
C is correct тАФ Soybean is a leguminous crop that facilitates nitrogen fixation through symbiotic bacteria in its root nodules.
When studying agricultural geography for competitive exams, always link 'Leguminous crops' to 'Soil Sustainability' and 'Green Manuring' to better understand the Nitrogen Cycle.
