Consider the following statements with reference to manure and organic farming:
- 1Vermicompost is rich in organic matter and nutrients.
- 2Biofertilizers and bio-pesticides are not used in organic farming.
- 3Crop rotation is beneficial in controlling insects, pests and weeds.
Which of the statements given above is/are correct?
General KnowledgeBiology
- A1 only
- B1 and 3 only
- C2 and 3 only
- D1, 2 and 3
Explanation
Vermicompost produced by earthworms is rich in humus, organic matter, and plant-available nutrients, so statement 1 is correct. Organic farming does permit biofertilizers (such as Rhizobium and Azotobacter) and biopesticides (such as neem formulations); only synthetic chemicals are banned, so statement 2 is false. Crop rotation disrupts pest and disease cycles and suppresses weeds, so statement 3 is correct. Hence statements 1 and 3 only are correct.
