Chromosols soil
WebAncient and highly weathered soils with very low levels of natural phosphorus (P) dominate much of Australia. Many of our agricultural soils are therefore among the most acutely … WebAs an example, there are sodic and vertic subgroups for Chromosols, which respectively indicate affinities with Sodosols and Vertosols . Another situation arises when similar soils are placed in different orders because B horizon pH is say 5.4 in one soil and 5.6 in another; by definition the former soils are Kurosols and the latter Chromosols .

Impact on Soils: Weathering of gabbro releases nutrient elements, such as calcium and potassium, which produce initially alkaline soils.
WebChromosols (Australian Soil Classification) are soils that have strong texture contrast between the surface (A) horizons and the clay subsoil (B) horizons.The subsoil is also not strongly acid i.e. pH is greater than 5.5 in water.
