What is burmeister soil classification system?

Burmeister soil classification system is a soil classification system that was developed by Dr. Herman Burmeister of Germany in 1890. This system is based on the concept that soils are defined by their physical properties, including texture, structure, and color. There are seven basic soil classes in the Burmeister system, including sands, loamy sands, sandy loams, loams, silt loams, clays, and peats. These classes are based on soil particle size, with sands having the largest particles and clays having the smallest particles.

The Burmeister system also includes subdivisions for each soil class based on additional physical properties, such as drainage, organic matter content, and soil depth. The subdivisions are identified by adding a letter after the soil class name, such as "S" for poorly drained sands or "C" for clayey soils.

This soil classification system was widely used in the early part of the 20th century but has since been replaced by more modern systems, such as the USDA Soil Taxonomy and the FAO Soil Classification System. However, the Burmeister system is still used in some parts of the world, especially in Germany and other European countries.
