Difficulty: EasyPlant Science and Agricultural Technology

With reference to modern agricultural techniques, consider the following statements regarding 'Fertigation':
1. Fertigation is the application of water-soluble fertilizers to crops through an irrigation system.
2. It significantly reduces nutrient leaching into groundwater compared to conventional broadcast fertilizer application.

Which of the statements given above is/are correct?

  1. A
    1 only
  2. B
    2 only
  3. Both 1 and 2Answer
  4. D
    Neither 1 nor 2

Answer

Both 1 and 2 are correct.
Fertigation is the method of applying fertilizers through an irrigation system (most commonly micro-irrigation or drip irrigation). By spoon-feeding water-soluble nutrients directly to the root zone at required times, it minimizes nutrient losses caused by leaching, volatilization, and surface runoff.

Step-by-Step Solution

1
Define Fertigation
Fertigation combines fertilization and irrigation by injecting liquid or soluble fertilizers directly into the drip or micro-irrigation network.
To verify the accuracy of the first statement.
2
Analyze Environmental and Efficiency Impacts
Because nutrients are supplied directly to the active root zone in controlled quantities, fertilizer efficiency increases and runoff/leaching into groundwater is minimized.
To verify the accuracy of the second statement.
