Question:
Which of the following is NOT the pillar of conservation tillage?
Which of the following is NOT the pillar of conservation tillage?
Show Hint
The 3 Pillars of Conservation Agriculture: 1. Minimum soil disturbance (No-till), 2. Permanent soil residue cover ($> 30\%$), 3. Crop diversification/rotation.
Updated On: Sep 4, 2026
- Minimum soil disturbance
- Soil cover with crop residue
- Nutrient management
- Crop diversification
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Conservation Agriculture (CA) is an agro-ecological farming paradigm standardized by the Food and Agriculture Organization (FAO) based on three fundamental pillars.
Step 2: Detailed Explanation:
The three universally defined core pillars of Conservation Agriculture (CA) are:
1. Pillar 1: Continuous minimum mechanical soil disturbance (zero tillage or direct seeding).
2. Pillar 2: Permanent organic soil cover with crop residues, cover crops, or living mulch (at least 30% ground cover).
3. Pillar 3: Species diversification through spatial and temporal crop rotations and associations.
While nutrient management is a good agronomic practice, it is not one of the three foundational pillars defining conservation tillage/CA.
Step 3: Final Answer:
Therefore, Nutrient management is NOT a foundational pillar of conservation tillage, matching option (C).
