They generally are less than 2 inches thick and are massive Crusts are created by the breakdown of structural units by flowing water or raindrops or through freezethaw action Soil crusts are generally only a temporary condition Typically the soil im Compaction changes soil structure reduces the size and continuity of pores and increases soil density bulk density Wheel traffic or pressure weight per unit area exerted on the soil surface by large animals vehicles and people can cause soil compact The significance of bulk density depends on the soil texture Rough guidelines for the minimum bulk density at which a root restricting condition will occur for various soil textures are gcc stands for grams per cubic centimeter Bulk Density extur gc A biological crust is a living community of lichen cyanobacteria algae and moss growing on the soil surface and binding it together A chemical crust or precipitate is white or pale colored and forms in soils with a high content of salts Both chemica Dr. Zamanzadeh (Zee).
