Q. With reference to Sulfur-coated Urea, consider the following statements:
1.Sulphur-coated urea is a type of fertilizer that releases nitrogen rapidly, causing plants to experience excessive nutrient uptake and leading to environmental pollution.
2.Sulphur-coated urea helps to minimize nitrogen leaching in waterlogged conditions for rice and wheat cultivation.
Select the correct statements using the codes given below:
Answer: B
Notes:
Explanation –
Statement 1 is incorrect. Sulphur-coated urea is a type of controlled-release fertilizer that is made by coating urea with sulphur and wax that increases nitrogen efficiency, improves plant growth and reduces water pollution. The purpose of the coating is to slow down the release of nitrogen into the soil, providing a more gradual and sustained supply of nutrients to the plants. In addition, sulfur itself is a secondary nutrient and it does not pollute the soil when applied appropriately.
Statement 2 is correct. Sulphur-coated urea helps to minimize nitrogen leaching in waterlogged conditions for rice and wheat cultivation.
