Every soils map represents an area dominated by one to several to many different kinds of soil. These different kinds of soil are called components. Components are each individual soil with individual properties that are grouped together for simplicity's sake when characterizing the map unit.

Soil can begin from anywhere above the un-weathered bedrock. Which can be only 1 foot deep in areas ,, and 20 feet deep elsewhere.
When you are dealing with peat and acid bogs ,, the defination is usually governed by local Laws and assumptions. ( So , bogs are measured differently in America and Germany.)
According to the Law it is usually conveniently 4 feet on the soil maps.
One way to distinguish componentry is to say the organic versus mineral content
OR also to distinguish layers of A , B , C
Or even layers 00 , 0 , A , B , C , D.
(** and in fact adding a B3 layer indicates a slower , more deliberate "aging" of the soil.)(Regions of 70-80" rainfall may be absent of C and D layer.)
There is a very marked change in soil morphorlogy between soils above and below 60" of annual rain.
80% of the world's soil-types are found in areas below 55" of annual rain. Due to persistance of minerals Ca , K and brine.

i might decide to understand extra relating to the properties of the soil to respond to this good. What are the climate? do you opt to understand the quantity of distinctive gradations of soil? it is oftentimes finished with sieve diagnosis.you will hit upon out the air quantity by utilising saturating the soil and taking the mass then placed it interior the oven and take the mass decrease returned as rapidly as thoroughly dry. you will then understand the wieght of the water and for this reason the quantity for the reason that a million gram H2O = a million cm^3.
