Answer 2

Soil acts as complete living system. The soil can be fertile, barren or even sick. Soil needs to be full of minerals and nutrients to provide the plants with maximum benefits to live.  Biologically, minerals can be replenished into soil by adding compost to it, which is created using wastage via several techniques. In addition, all the living beings carry minerals. These minerals transfer to the soil upon the death of the living being as the body gets decomposed in soil and replenishes the minerals of the soil.
