Aggregate composition
Aggregate composition is the quantitative distribution of soil clumps (aggregates) of various sizes within the arable layer of the soil.

Understanding aggregate composition is crucial for assessing soil structure. Agronomists analyze it to determine water stability and aeration, which directly influence the root development of crops.
Testing is typically performed before planting or following deep cultivation. Ideally, the soil should be dominated by aggregates ranging from 0.25 to 10 millimeters in size. It is important to note that excessive mechanical tillage can pulverize the soil into dust, leading to surface crusting and increased erosion risk.
A common mistake is working the soil at incorrect moisture levels. Working on overly wet soil causes structural degradation and compaction, which hinders seed germination and root penetration.
