Explanation: 

Detailed explanation-1: -Vegetation plays an important part in the formation of soils from solid rock. The acids released by the roots of some plants act to breakdown the rock on which the soil is forming. The vegetation on a soil is particularly important in supplying the soil with precious organic matter.

Detailed explanation-2: -Among these, the conversion from forest to agricultural land triggers one of the most severe changes: the loss of soil organic carbon. Other impacts include the use of pesticides, which decreases soil biodiversity, intensive irrigation leading to soil salinisation, and the accumulation of heavy metals in polluted soil.
