Module Overview

The movement and retention of water and gas in soil play a fundamental role in soil health, plant growth, and overall ecosystem function. These physical processes influence critical factors such as root respiration, nutrient availability, microbial activity, and soil structure. Understanding how water and gases behave within soil can help inform land management practices and support the design and development of sustainable soils. This module covers the physical properties of gas and water in soil and their key roles in soil health and suitability. It highlights how these properties affect critical processes like oxygen depletion during waterlogging and aids in diagnosing issues such as drainage problems. Case studies are included to illustrate examples of drainage challenges and effective solutions in various soil environments.
