Terra rossa is a polygenetic relict soil, formed during the Tertiary and subjected to hot and humid periods during the Quaternary. Color:

Vary from orange to reddish brown and various shades of red in color Origin: Developed on limestone or dolmite. Type: Heavy and clay-rich (silty-clay to clayey) soil,

B Depth of the soil

Clay erosion Grain erosion Sand erosion Gravel erosion Terra Rosa (Heavy Soil) Can be used for agriculture due to the codensation of organic matter due to soil erosion

Section B-B Soil Types

Color is Brighter in the sample 2 Due to the accumulation of Calcium from the soil erosion. Organic matter: No natural organic matter due to the human agricultural Behaviour

Plant Extraction of water due to soil porosity

Crust

The Soil have a crust surface which prevents water and air from getting throught the soils pores

Which makes it harder to plant in. And increases the possibility of water floods. In addition to the destruction of the soil and its erosion due to the closness to the water flow. Soil Shrinkage

Due to the polarity of water (H2O), when it gets through the soil it inflates it. when the water dries out. the soil shrinks through time this leads to the cracking of the soil and the reduction of its benifits
