What is a Kurosol soil?
Kurosols (Australian Soil Classification) are soils that have strong texture contrast between the surface (A) horizons and the clay subsoil (B) horizons. The subsoil is strongly acid, i.e. pH is 5.4 or less in water, and non-sodic (at least in the upper horizons).
What are Podosols?
Podosols (Australian Soil Classification) are mainly sandy soils with accumulations of organic materials and aluminium (with or without iron compounds) in subsoil horizons. These deep sandy soils are strongly acidic and have accumulations of ‘coffee rock’ in the subsoil.
What type of soil does NSW have?
The main soil types are Vertosols, Chromosols and Ferrosols. In both regions the dominant winter crop is wheat with canola, barley, triticale and a variety of winter pulses including chickpea, lupin, faba bean and lentil also produced during winter.
How are Calcarosols formed?
Calcarosols (often called ‘mallee loams’,’mallee sands’ or ‘calcareous earths’) are soils formed on calcareous aeolian sediments of variable texture. They generally have a small, gradual increase in clay content with depth (ie. not as strong texture contrast between surface soil and subsoils as compared to Sodosols).
What are podzolic soils?
podzolic soil, podzolic also spelled podsolic, also called lessivé soil, soil usually forming in a broadleaf forest and characterized by moderate leaching, which produces an accumulation of clay and, to some degree, iron that have been transported (eluviated) from another area by water.
What is Ferrosol soil?
Ferrosols are soils lacking strong texture contrast between surface (A) horizons and the upper subsoil (B21) horizon. These soils are also characterised by relatively high levels of free iron oxide i.e. free iron oxide content greater than 5%.
What is soil Gleization?
Gleization – A process of soil formation under an anaerobic environment and leading to the development of a gley horizon with green-blue colors, related to the reduction of soluble ferrous iron under water-logged conditions.
What soil is loamy?
What Is Loam? Loam is soil made with a balance of the three main types of soil: sand, silt, and clay soil. As a general rule, loam soil should consist of equal parts of all three soil types. This combination of soil types creates the perfect soil texture for plant growth.
Where is the most fertile soil in Australia?
The Lockyer Valley is rated among the top ten most fertile farming areas in the world, and the intensively cultivated area grows the most diverse range of commercial fruit and vegetables of any area in Australia.
What is Tenosol soil?
Tenosols have a weakly developed soil profile which is typically very sandy and without obvious horizons. Tenosols form from highly salicious parent material and where rainfall is from 0 to 1400mm. Ground-water contamination can be a potential problem due to the high permeability of these soils.
Is podzolic soil good?
Most Podzols are poor soils for agriculture due to the sandy portion, resulting in a low level of moisture and nutrients. Some are sandy and excessively drained. Others have shallow rooting zones and poor drainage due to subsoil cementation.
