A soil aggregate is "a group of primary soil particles that cohere to each other more strongly than to other surrounding particles." Soil aggregates form through the combined action of aggregation and fragmentation processes. That is, attractive and disruptive forces act on the particles in the soil to cause greater cohesion among some individual particles and groups of particles than others.
