If we have a dark colored, coarse soil and reddish smooth soil for comparison, we can find lots of differences in them.
- The dark soil will have bigger layer of humus, while the reddish one will have a very small almost unnoticeable layer of humus.
- The color differs a lot, while the dark soil will have a dark brownish color, the reddish one will have intense orange-red color.
- The vertical profile of the soils will differ a lot; the dark one will have much bigger top two layers, while the reddish one will have very small upper layers and dominant middle layer.
- The dark soil will be rich in biomass, while the reddish one will be rich in iron and clay.
