What is the necessity of using conservation tillage methods?

The rapid and ever-increasing population and the demand for nutrition reveal the necessity of planning to provide sufficient food. The discussion of sustainable agriculture has become more important during the last two decades and a lot of research has been done in this field. One of the fundamental and vital issues in the production cycle of agricultural products is how to perform tillage operations. The high vulnerability of the soil during the tillage operation and the steps after it, has led to the use of more effective methods to protect the soil and increase productivity in the long term. In this regard, the use of conservation tillage methods instead of the usual and traditional methods, in addition to protecting the soil against water and wind erosion, will have positive effects on the soil structure, the environment and the productivity of water resources.
