The permissible maximum biuret content of urea produced in India is?

✅Explanation:In India, the maximum allowable biuret content in urea is 1.50%. Biuret is a byproduct formed during the production of urea, and while small amounts are generally safe, higher concentrations can be harmful to plants. Excessive biuret can cause toxicity and inhibit plant growth, so it is regulated to ensure safe agricultural use of urea fertilizers.
