Soil microaggregates
Soil microaggregates are microscopic clusters of soil particles, typically smaller than 0.25 mm, bound together by organic matter, fungi, and minerals.

The importance of microaggregates lies in their ability to improve soil porosity and structure, which facilitates better water infiltration and root respiration. These structures act as protected micro-habitats that store organic carbon and protect it from rapid decomposition by soil microbes.
In field management, maintaining these aggregates is crucial for soil health. Typical mistakes include excessive tillage and the use of heavy machinery, which break down microaggregates, leading to soil compaction and reduced productivity. Avoiding soil inversion during wet conditions helps preserve these fragile structures.
To support microaggregate stability, agronomists recommend regular application of compost or manure and the use of cover crops. High biological activity and sufficient soil organic matter are the key factors in keeping these aggregates stable and promoting a healthy soil environment.
