How much amount of urea will be required for supplying 1 kg of nitrogen?

🌿 Key Points
→ Nitrogen:
Promotes rapid plant growth and improves grain yield and grain quality.
N is the most limiting nutrient as it is needed in large amounts and is easily lost through volatilization (gas loss) and leaching (washing out of the root zone).
→ Phosphorus:
Can be applied as rock-phosphate or as mineral fertilizer.
→ Red Soils:
Contain significant amounts of iron oxide.
Farmers need to apply large quantities of phosphorus fertilizer for availability to plants in such soils.
→ Potassium:
Mainly found in compound fertilizers, such as 10-20-20.
