Multiple Choice

The Plant Available Moisture Pool is increased by irrigation.

Explanation:
The key idea is that the Plant Available Moisture Pool is the amount of water in the root zone that plants can use, bounded by wilting point and field capacity. Irrigation directly adds water to the soil profile, so the moisture in the rooting zone increases. As long as the soil isn’t already at field capacity, this additional water increases the portion of water available to plants, expanding the Plant Available Moisture Pool. If the soil is already at field capacity, extra irrigation won’t raise the pool and can lead to drainage, but in typical cases irrigation does increase plant-available water.
