What is water that drains from the macrospores called?

Water that drains from the macrospores is referred to as gravitational water. This type of water moves through the soil due to the force of gravity, filling the larger pores or macrospores of the soil. When precipitation occurs or when soils are saturated, gravitational water is the excess water that drains downward, typically beyond the reach of plant roots. It's important for understanding soil moisture dynamics, especially in terms of how water availability can affect plant health and growth.

Capillary water, on the other hand, refers to water that is held in the smaller pores of the soil, where it is available to plants. Saturation water describes the condition when all the soil pores are filled with water, which may not be usable by plants. Groundwater describes water that is stored beneath the earth's surface in aquifers and is not specifically related to the drainage from macrospores. Understanding these distinctions enables arborists and soil scientists to manage and predict water availability in relation to plant health and soil management practices.
