In the whole world, chemicals based modern agriculture itself imparts a great role in degradation in soil health, whose priority is always only high crop productivity. In the Agricultural sphere, an extensive knowledge on soil degradation is already present. Consequently, the excessive use of synthetic fertilizers, the systematic deforestation, soil erosion due to high tillage and the action of rains or winds, loss of organic matter and several other factors brought about increasing desertification, the loss of millions of tons of fertile top soil and, indirectly, silted up rivers and lakes, caused soil salinisation, climate changes and loss of biodiversity. Besides the need for constant monitoring and evaluations of physical-chemical and biological processes to achieve better soil health, it is imperious to keep in mind that soil organic matters are the main agents of nutrient cycling and also have a complex interaction with plants.
