OBJECTIVE FORESTRY

Detailed explanation-1: -Sub soil:-it is the middle layer of the soil. the roots of the trees and plants reach up to the subsoil. Bed rock:-it is the last layer of the soil. it is fully covered with rocks so it is called the bed of rocks.

Detailed explanation-2: -In general, most tree roots can grow anywhere from two to six feet deep. However, there are some tree roots that have been known to grow much deeper than that. The world’s deepest tree root was found in South Africa, and it reached a depth of 24 feet!

Detailed explanation-3: -As the stem and leaves grow on the surface, additional roots expand underground. Lateral roots branch off the tap root. These form close to the surface of the soil where most of the water and nutrients are found. Thus a wide matt of roots radiates out from the trunk, parallel with the soil, creating a “root plate”.
