What is the result of small amounts of water in soil?

Small amounts of water in soil contribute positively to the aggregation of soil particles. When water infiltrates soil, it forms a thin film around individual particles, promoting cohesion. This moisture acts as a binding agent that helps particles clump together, enhancing soil structure and stability. These aggregates increase the soil's ability to retain nutrients and water, ultimately fostering a healthier ecosystem for plants.

In contrast, while excessive water may lead to problems like erosion or landslides, small amounts typically improve the physical properties of the soil rather than deteriorate them. This balance is essential for maintaining productive agricultural and natural landscapes.
