Question

Which of the following is not a method used in sustainable agriculture?

• A. Composting
• B. Biogas production
• C. Fodder production from plant waste
• D. Use of chemical fertilisers

Answer 1

The correct option is D

Use of chemical fertilisers

Sustainable agriculture is a step adopted to reduce the use of chemical fertilisers and pesticides. This method also emphasises on the use of agricultural wastes efficiently and aims at reducing environmental pollution. Composting, biogas production and fodder production from plant waste are all methods of sustainable agriculture. Addition of chemical fertilisers to increase soil fertility leads to environmental pollution. These chemicals can also enter the food chain and cause human health issues.
