Mikroaggregates

Mikroaggregates are small, discrete clusters of soil particles that are held together by organic matter, microbial byproducts, and clay. These aggregates play a crucial role in soil structure and health. They are typically less than a millimeter in diameter and are the building blocks of larger soil aggregates. The formation of mikroaggregates is a dynamic process influenced by the types of soil, the amount of organic matter present, and the activity of soil organisms.

The presence of stable mikroaggregates contributes to improved soil aeration and water infiltration. This is because the spaces between these small aggregates allow for better gas exchange and water movement through the soil profile. Furthermore, mikroaggregates can protect organic matter from rapid decomposition, contributing to the long-term carbon storage in soils. They also provide habitats for beneficial soil microorganisms, supporting a diverse and active soil food web.

Factors such as tillage, compaction, and extreme weather conditions can disrupt the formation and stability of mikroaggregates, leading to soil degradation. Sustainable land management practices, including reduced tillage and the incorporation of organic amendments, are important for promoting and maintaining mikroaggregate formation. Understanding the role of mikroaggregates is essential for soil scientists and farmers aiming to improve soil quality and agricultural productivity.
