Drought is no longer an exceptional risk for agriculture; it is the new reality of the system. Uncertainty in precipitation regimes, prolonged water scarcity, and sudden heat waves not only make production difficult but also unpredictable. Today, the main question is: How can production be made sustainable with less water? The answer to this question does not lie in a single application, but in a new approach that addresses plant physiology, soil structure, and the entire production system together.
