Full soil profile can be formed during 2000 - 3000 years which depends on environmental conditions. Acording to short-term climatic changes (from warm-dry to the cool-wet phases or in reverse) rates of pedogenesis will be changed and soil profile will formed significantly faster. If the soil will be formed not from the parent rock but, for example, from the soil material previous soil (how can this happen on earth mounds or ramparts) rates of pedogenesis will being more. E.g., 20 cm of humus horizont was being formed during about from 1914 to present. On earth ramparts soil with thickness about 40-50 cm is developing 1000 years. In natural landscapes quite quickly soil evolution takes place also on flood plains
