Aggregate(s) [clump(s)]
a group of soil particles that cohere to each other more strongly than to other surrounding particles.
Discussion—Soil aggregates can be natural (a ped) or formed by human activities (a clod). Often the genesis of evidentiary soil aggregates is unknown, so aggregate is often a preferred term in
descriptions of soil evidence.
Discussion—This use of the term aggregate is distinct from this term’s use in construction as the sand or crushed rock mixed with cement to form mortar, grout, or concrete.
