Abstract

Humans need food to survive, which is obtained from the presence of water and soil. Soil is a valuable element in the continuity of the earth and one of the most valuable vital resources because it ensures the growth of plants and meets more than 97 percent of the world's food needs. Therefore, it plays an important role in the production of agricultural products and food security, and saving the lives of all creatures is related to saving this vital substance.
Agricultural productivity in any country is closely and tightly linked to the quality and depth of its agricultural soil, and it can be said that any country that has richer, more fertile and abundant soil resources and exploits them in the best and most appropriate way has guaranteed its stability, sustainability, security and prosperity.
Although scientifically, soil is considered a renewable natural resource, in practice it is considered a non-renewable resource due to the slow process of its formation.
Given that soil is a non-renewable natural resource and has multiple and vital roles in nature, its preservation is essential for a sustainable future, and it is seriously time to preserve and protect the soil and keep it alive for present and future generations with the efforts of people, experts and officials.
