blanched soilThe bleached-layer soil is a layer of soil formed by the loss of clay particles and/or free iron dioxide, sometimes accompanied by the in-place condensation of iron dioxide. Its color was mainly determined by the sand particles and powder particles that formed the whiteness. The bleached layer was usually composed of bleached substances, including segregated iron-Mn agglomerations, agglomerations, and patches. The whiteness itself showed the characteristics of the color, such as a tint lower than 2, a moistened lightness greater than 3, a dry lightness greater than 6, and so on. The thickness of the blanched layer was generally between 20-30cm. Its distribution and formation in the soil are related to the clay content, iron dioxide content, water eluviation and drainage of the soil. There was a specific level of diagnosis for the bleached layer in the soil systematic classification. For example, there was a classification for the bleached layer in both the Chinese soil systematic classification and the American soil systematic classification. However, there were still some disputes and differing views on the cause and nature of the bleachers.
