This soil is "Terra Rossa" (Red Soil), classic Mediterranean soil type is generally a mix of clay soil. The reddish color is because of "Hematite" (Fe[SUB]2[/SUB]O[SUB]3[/SUB]) which is generally 4-6% of the soil. Although the parent rock is limestone it's not too much limey because of washing effect. Because of the warm climate, humidity and abundant rains (except summer) everything decomposes and oxidises quickly, so it does not contain enough humus (organic matter). This type of soils are generally located at mountain slopes. Because of these facts, it's not a rich soil and generally used as growing olive and it's also popular for wine production. On the other hand, although it has good amount of clay its drainage is really good because of the bigger particle size.
