Introduction
What is soil?: the upper layer of earth in which plants grow, a black or dark brown material typically consisting of a mixture of organic remains, clay, and rock particles.
Why do we need soil?: Without the soil, humans would be unable to eat fruits, vegetables and meat. Soil regulates the Earth's ecosystems by supporting a wide variety of flowering plants and enabling farming and food production. The rate of farming has grown exponentially in recent years due to the development of highly mechanized techniques that increase the effectiveness of soil. Fertilizers are also used to improve the quality of soil in farmland so that agricultural products can be grown abundantly and shipped over vast distances.
