Soil depth information is related to the depth of the plant root system in order to find food and support for the stem. The deeper the soil, the better the roots of the plants and there are 5 different levels such as: (1) Extreamly shallow (R) <30 cm, (2) Shallow (S) 31-50cm, (3) thin (T) 51-75cm, (4) Medium shallow (M) 76-100cm, and (5) Deep (D) >100cm <\/SPAN><\/P>
