What are 3 shared features does a soil series share?
Each series consists of soils having major horizons that are similar in color, texture, structure, reaction, consistence, mineral and chemical composition, and arrangement in the soil profile.
What is soil series in the Philippines?
There were nine groupings of the Philippine soil series, based on physiography, the kind of parent material and mode of formation, and the kind of soil profile. The alluvial soils were placed in groups 1–5, group 6 was basically a mix of alluvial and residual soils, and groups 7–9 were residual soils.
What is a soil series example?

How many soil series are there?
More than 14,000 soil series are recognised in the United States. This permits very specific descriptions of soils. A soil phase of series, originally called ‘soil type’ describes the soil surface texture, slope, stoniness, saltiness, erosion, and other conditions.
What are Type 3 soils?
Class III (3) soils have severe limitations that reduce the choice of plants or require special conservation practices, or both. Class IV (4) soils have very severe limitations that restrict the choice of plants or require very careful management, or both.
What are the 3 main types of soil?
The particles that make up soil are categorized into three groups by size – sand, silt, and clay. Sand particles are the largest and clay particles the smallest. Most soils are a combination of the three.
What is the purpose of soil mapping?
Generally, soil maps are used to simply identify soils and their properties, but are sometimes required for more specific purposes, such as determining the suitability of a soil for particular crops, or the land drainage capabilities of an area. Like all maps, soil maps can be created in different scales.
