Step 1: Understanding the Question:
This question tests knowledge of conservation agriculture principles.
Step 2: Detailed Explanation:
Conservation agriculture involves minimal soil disturbance (no-till or reduced tillage).
Biological tillage (by earthworms and roots) is allowed.
This statement is true.
In the initial years of conservation agriculture, weed infestation is high due to the accumulation of weed seeds on the surface.
Over time, weed seed bank decreases and weed pressure reduces.
This statement is also true.
Thus, both statements are true.
Step 3: Final Answer:
Thus, both statements are true, which corresponds to option (A).
