Assertion : Nowadays people realised that there is a large pressure to switch to organic farming. Reason : Biofertilizers are organisms that enrich the nutrient quality of soil.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Organic farming is an agriculture practice which uses renewable resources, causes minimum pollution and maintains optimum yield. The various components of organic farming are Biofertilizers, Biopesticides and non-use of artificial fertilizers and chemical pesticides.

Which one of the following is symbiotic biofertilizer?
1 Azotobacter
2 Clostridium
3 Beijerinckia
4 Rhizobium
Explanation:
Rhizobium is a symbiotic nitrogen fixing organism which fixes atmospheric nitrogen to ammonia and forms root nodules in legume plants thus, responsible for increase in nitrogen content of soil.
