Assertion and Reason:Assertion: Biofertilizers are organisms that enrich the nutrient quality of the soil.Reason: Organic farming is the farming technique in which no chemical is used as fertilizers or insecticides.The assertion is correct but the reason is incorrect.Explanation:Biofertilizers are living organisms that enrich the nutrient quality of the soil. They are natural and eco-friendly alternatives to chemical fertilizers. They contain microorganisms like bacteria, fungi, and algae that help in fixing atmospheric nitrogen in the soil, solubilizing phosphorus, and enhancing the availability of other essential nutrients like potassium and sulfur. Biofertilizers are used in organic farming as well as conventional farming practices to improve soil fertility and crop yield.On the other hand, organic farming is a farming technique that excludes the use of synthetic fertilizers, pesticides, and genetically modified organisms. It relies on natural inputs like compost, manure, and biofertilizers to maintain soil health and fertility. While the use of biofertilizers is common in organic farming, it is not the only technique used.Therefore, the assertion that biofertilizers enrich the nutrient quality of the soil is correct, but the reason that organic farming excludes the use of chemical fertilizers is not entirely accurate. Organic farming may use certain types of natural fertilizers that are not considered biofertilizers, such as bone meal or blood meal.
