Hummus acids act as a natural chelating factor, binding metal ions in an alkaline environment and facilitate their uptake by the root system.
Chitosan is obtained from chitin, which has a higher plant to very high biological activity min . increasing plant resistance to adverse environmental conditions for fungal and bacterial infection .
