Arcillosos
Arcillosos refers to soils predominantly composed of clay minerals. These soils are characterized by very fine particle sizes, typically less than 0.002 millimeters in diameter. Due to their small particle size, clay particles have a high surface area, which leads to strong cohesive forces when the soil is wet. This cohesiveness is responsible for the plasticity of clay soils, allowing them to be molded when moist but hardening significantly when dry.
The properties of arcillosos soils can vary widely depending on the specific clay mineralogy, the amount of
Despite their limitations, arcillosos soils are fertile due to their ability to retain water and nutrients.
