What type of soils is classified under Class 0?

Class 0 soils, often referred to as organic soils, are characterized by their high organic matter content and are typically formed in wetland regions. These soils are rich in decomposed plant material known as peat, which gives them a dark color and a spongy texture. Organic soils are essential in ecological systems, contributing to water retention, providing habitat for various organisms, and influencing nutrient cycles.

In contrast, alluvial soils are deposited by running water, sandy soils are composed predominantly of sand particles and have good drainage but poor nutrient retention, while clay soils have fine particles that compact easily and tend to hold water. Each of these soil types has distinct properties, uses, and classifications based on their texture and formation processes, but it is the organic soils that specifically fit the criteria for Class 0 due to their unique composition and environmental significance.
