What is Type C soil?
What is Type C soil?
Type C soil is the least stable type of soil. Type C includes granular soils in which particles don’t stick together and cohesive soils with a low unconfined compressive strength; 0.5 tons per square foot or less. Examples of Type C soil include gravel, and sand. Clumps mean that the soil is cohesive.

What is a Type B soil?
Type B soil has medium unconfined compressive strength; between 0.5 and 1.5 tons per square foot. Examples of Type B soil include angular gravel, silt, silt loam, and soils that are fissured or near sources of vibration, but could otherwise be Type A. Type C soil is the least stable type of soil.
What is the type of soil in the Manila series?
The Manila series consists of very deep, well drained, slowly permeable soils that formed in colluvium and alluvium from sedimentary rocks. Manila soils are on alluvial fans, mountain slopes, hills, and fan terraces and have 0 to 50 percent slopes.
Where can I find official soil data and maps?
Search for lab data on a map, via custom filters. Web Soil Survey (WSS) provides official soil data and maps produced by the National Cooperative Soil Survey. It provides access to the largest natural resource information system in the world. More than 3,750 block diagrams (line drawings) from published soil surveys.
What is the pH of acidic soil in biology?
In strongly acidic soils (pH 5.5 to 4), important nutrients such as phosphorus, potassium, calcium and magnesium are in short supply. The availability of phosphorus, iron, copper, zinc and manganese is reduced in slightly to moderately alkaline soil (pH 7 to 8).
Where are Mollisols found in the Philippines?
Chernozems (Mollisols). These are very fertile soils due to their organic matter-rich topsoil. They can be found in limestone areas in Leyte, Bohol, and other islands. Old uplands were formed by volcanism or geologic uplift millions of years ago.
