The hidden plant-driven biological pathways that regulate soil water holding capacity
Soil water holding capacity is one of the most important and most misunderstood properties in soil science. Most conversations around it start and end with texture. Sand, silt, clay. It is a familiar framework, easy to measure and easy to compare. But here is the deeper reality: two soils with the same texture can behave very differently when it comes to holding water. So what is really controlling it? The answer sits below the surface, in something we do not always measure directly. Soil structure, and more importantly, how that structure is built. “Water retention is not just a physical property. It is a biological outcome, one that reflects the health and activity of everything living below […]
