Soil Compaction on Vegetable Farms
... Soil texture can also influence the compaction potential of a soil. Particles of similar size will compact less than a mixture of particle sizes, because smaller particles can fill in the pore spaces between larger particles. Thus, soils with a diverse mix of sand, silt, and clay are relatively susc ...
