1. Fertilization
2. Fertugation
3. Fertigation
4. Ferguration

Answer 1

Correct Answer - Option 3 : Fertigation

The correct answer is Fertigation.

• The mixing of fertilizer or chemicals in irrigation water is called Fertigation.

• Fertigation is a method in which fertilizer is mixed within the irrigation water by the drip system.
• In this system, fertilizer solution is distributed evenly in irrigated land.
• The availability of nutrients is very high therefore the efficiency is more and reducing the losses.
• In this method, both liquid fertilizers, as well as water-soluble fertilizers, are used. By this method, fertilizer use efficiency is increased from 80 to 90 per cent. 
• Advantages of fertigation:
  • Nutrients and water are supplied near the active root zone through fertigation which results in greater absorption by the crops.
  • As water and fertilizer are supplied evenly to all the crops through fertigation there is a possibility for getting a 25-50 per cent high yield.
  • Fertilizer use efficiency through fertigation ranges between 80-90 per cent and helps to save a minimum of 25 per cent of nutrients.
