What are the advantages of fertigation in agriculture?
1. Controlling the alkalinity of irrigation water is possible.
2. Efficient application of Rock Phosphate and all other phosphatic fertilizers is possible.
3. Increased availability of nutrients to plants is possible.
4. Reduction in the leaching of chemical nutrients is possible.
Select the correct answer using the code given below:
Explanation
Fertigation is a process in which fertilizer is dissolved and distributed along with water in
your drip or spray irrigation system. There is abundant research available that supports the
superiority of fertigation as compared to traditional fertilizing techniques.
Advantageous of fertigation:
• Increases nutrient availability (Hence, statement 3 is correct))
• Reduces leaching of nutrients (Hence, statement 4 is correct)
• Allows to alter the pH of the irrigation water (Hence, statement 1 is correct)
Disadvantages of fertigation
• Suitable for readily soluble or liquid fertilizers. Phosphatic fertilizer and some
micronutrients may precipitate in micro-irrigation system. Hence, statement 2 is not
correct. (statement 2 can be eliminated from the given options)
Therefore, the correct answer is (c).
