Which nutrient is primarily provided by leguminous crops, making them essential for soil nitrogen fixation?
Nitrogen
Potassium
Phosphorus
Calcium
Nitrogen
Leguminous crops like pulses and beans house Rhizobium bacteria in their root nodules, which convert atmospheric nitrogen into ammonia for plant uptake. This biological nitrogen fixation process naturally enriches the soil, reducing the requirement for synthetic nitrogenous fertilizers.
Leguminous crops like pulses and beans house Rhizobium bacteria in their root nodules, which convert atmospheric nitrogen into ammonia for plant uptake. This biological nitrogen fixation process naturally enriches the soil, reducing the requirement for synthetic nitrogenous fertilizers.
The Indian Council of Agricultural Research (ICAR), established in 1929 under the Societies Registration Act, 1860, remains the apex body for coordinating and managing research and education in agriculture, including soil science and nitrogen management.
Rhizobium bacteria share a symbiotic relationship with leguminous plants.
Nitrogen fixation is essential for maintaining soil fertility in intensive cropping systems.
Crop rotation with legumes is a standard agricultural practice to restore soil nitrogen levels.
Legumes enrich the soil specifically with nitrogen, unlike Potassium (B), Phosphorus (C), or Calcium (D) which are primarily sourced from minerals or synthetic fertilizers.
Option B (Potassium) is an essential macronutrient but is typically provided through fertilizers like MOP (Muriate of Potash).
Option C (Phosphorus) is vital for root development and energy transfer, usually sourced from DAP (Diammonium Phosphate).
The process of nitrogen fixation is a cornerstone of sustainable organic farming in India.
A is correct тАФ Leguminous crops facilitate the fixation of atmospheric nitrogen into the soil through symbiotic bacteria.
In Geography and Economy, link this to the Green Revolution; while the Green Revolution focused on high-yield varieties requiring heavy synthetic fertilizers, modern Sustainable Agriculture focus points are shifting back to natural nitrogen fixation methods like green manure.
