Soil structure refers to the arrangement of soil particles and the spaces between them. It influences how air, water, and nutrients move through the soil, affecting plant growth. Soil can have different structures, such as granular, blocky, or platy, each impacting its ability to retain moisture and support root systems. Good soil structure promotes healthy ecosystems by allowing roots to penetrate easily and facilitating the movement of organisms like earthworms. It is essential for agriculture, as it affects crop yields and soil fertility. Maintaining soil structure is crucial for sustainable land management and environmental health.
