What is the term for the amount of water held in the soil after drainage occurs?

Water Holding Capacity
course textured particles
Soil Testing
Nomenclature

The correct answer is: Water Holding Capacity

Water Holding Capacity refers to the amount of water that can be held in the soil after excess water drains away. This term is essential for understanding soil's ability to retain water, which is crucial for the growth and health of trees and plants. Options B, C, and D are not related to the concept of the amount of water held in the soil after drainage, making them incorrect in this context. Option B, coarse textured particles, refers to the size of particles in the soil. Option C, Soil Testing, is a general term for analyzing soil properties, which can include determining water holding capacity but is not the specific term for it. Option D, Nomenclature, pertains to the system of naming things rather than a term related to water holding capacity in soil.
