WebMar 1, 2024 · The preliminary study found that when using red soil as a substrate to treat livestock wastewater in the constructed wetland, the anaerobic zone of the substrate bed underwent a strong iron reduction phenomenon; that is, in the anaerobic zone of a wetland rich in organic carbon, iron oxide in red soil can be reduced to ferrous in large ... Soil color is produced by the minerals present and by the organic matter content. Yellow or red soil indicates the presence of oxidized ferric iron oxides. Dark brown or black color in soil indicates that the soil has a high organic matter content. Wet soil will appear darker than dry soil. However, the presence of water also affects soil color by affecting the oxidation rate. Soil that has a high water content will have less air in the soil, specifically less oxygen. In well drained (and therefore o…
