| Masa soil had the lowest threshold of SWC and erosivity to initiate erosion followed by Sand soil, Oxisols and Andosols. |
| The resulting soils, called oxisols, are deep red in colour, are infertile, and may even harden irreversibly into bricklike laterite after being drained and cultivated. |
| Structure is subangular blocky to semi-angular blocky for Ultisols and subangular blocky to strong granular for Oxisols. |
| These soils used to be called latisols, but are called oxisols and ultisols by the USDA and ferralsols or acrisols by the UN these days. |
| Oxisols occupy 7 percent of the nonpolar continental land area on Earth, mostly in the equatorial regions of South America and Africa. |
| Because the present climate can never produce enough weathering to produce oxisols, torrox soils are always paleosols formed during periods of much wetter climates. |
