the soil problem
How can a comic strip effectively illustrate the problem of soil erosion?
The comic strip could start by explaining what soil erosion is, then show examples of it happening in real places. Maybe it has diagrams to show how water or wind causes the erosion. And it could end with suggestions on how to prevent it. That would make for a comprehensive and effective illustration.

blanched soil
The 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.

The fragrance of soil in novels
There was currently a novel called " The Fragrance of Earth ", but there was not much detailed explanation about this novel. There were also some literary works that mentioned " soil fragrance " in the description. For example, in the reading experience of White Deer Plain, it was mentioned that it seemed to smell the fragrance of soil. This reflected that the soil fragrance of the novel might be an expression of the local flavor, rural life scenes, and cultural implications. For example, White Deer Plain showed the local style of the Guanzhong Plain through the story of White Deer Village, people's life and labor, etc. These elements may together form the local characteristics of the novel like " soil fragrance." In addition, when authors created literary works such as novel collections and poetry collections, the names of their works also contained soil elements, such as "The Soil of the Kiln Transformation", which might also be a manifestation of this local flavor in literary works.
