Agronomy QUESTION #2051
Question 1
Conservation agriculture (CA) is based on three core principles. Which combination correctly identifies all three?
  • Deep plowing + high input use + crop rotation
  • Minimum soil disturbance (no/minimum tillage) + permanent soil cover (mulch/crop residues) + crop species diversification (rotation/intercropping)✔️
  • Organic farming + biological pest control + rainwater harvesting
  • Precision irrigation + slow-release fertilizers + integrated pest management
Correct Answer Explanation
FAO defines Conservation Agriculture by three linked principles: (1) minimum mechanical soil disturbance, (2) permanent organic soil cover with crop residues or cover crops, and (3) species diversification through crop rotations and/or intercropping. All three must be practiced simultaneously for CA to deliver its full benefits.
