Biuret formation in urea is kept at minimum (< 1 %), because it is___________________?
Correct answer: C. Toxic and harmful to some crops
- A. Corrosive in nature
- B. Helpful in decomposition of urea
- C. Toxic and harmful to some crops
- D. Explosive in nature
Explanation
Biuret can inhibit seed germination and damage or become toxic to sensitive crops, so its concentration in urea is controlled below about 1%. Its main concern is crop injury, not corrosion or explosiveness.
