Soil structures refer to the arrangement and organization of soil particles and the spaces between them. This arrangement affects how water, air, and nutrients move through the soil, influencing plant growth and ecosystem health. Soil structures can be classified into various types, such as granular, blocky, and platy, each with distinct characteristics. The formation of soil structures is influenced by factors like climate, organisms, and parent material. For example, the activity of earthworms and other soil organisms can enhance soil structure by creating channels that improve aeration and drainage. Understanding soil structures is essential for effective land management and agriculture.
