Why is the soil so red?
Materials that remain are composed mostly of iron, aluminum, and silica, and it is the iron that gives the soils the red color. The red color is not just from iron, but more specifically from unhydrated iron oxides. The red soils are generally on convex landforms that are well drained.

Which soil is best red or black?
Soil colour Pale soil needs plenty of organic matter and mulching. Red soil usually indicates extensive weathering and good drainage, but often needs nutrients and organic matter. The red colour is due to the oxidising of iron compounds (‘rusting’) in the soil.
