What method involves pre-digging to create a denser root system?

Field Capacity
Buffering Capacity
Root Pruning
Macropores

The correct answer is: Root Pruning

Root pruning involves cutting or trimming specific roots to encourage the development of a denser root system. By selectively removing certain roots, the plant is stimulated to produce new feeder roots in the pruned area, resulting in a more concentrated and efficient root system. This technique is often used to manage root growth, improve tree stability, and promote overall tree health. Regarding the other options: - Field Capacity refers to the amount of water soil can hold against gravity, which is unrelated to root pruning. - Buffering Capacity is the ability of soil to resist changes in its pH level, which is also not related to root pruning. - Macropores are large soil pores that allow for the movement of air and water within the soil, but they are not associated with the process of root pruning.
