soil structure
Ground particle arrangement
Soil structure describes how individual soil particles clump together into larger aggregates.
Good structure creates pores for air and water movement, root growth, and organism activity: The clay soil had poor structure and drained slowly.
Farmers and gardeners work to improve soil structure through adding organic matter, minimizing tillage, and avoiding compaction.
