The main difference between the ZERYA Pesticide Residue-free and ZERYARegenerativa programmes lies in their approach and objectives. The ZERYA Pesticide Residue-free program focuses on the production of food that guarantees a final product without detectable pesticide residues, using a technical management system that includes prevention, biological control and rational use of phytosanitary products. On the other hand, ZERYARegenerativa encompasses agricultural practices focused on the regeneration and improvement of agricultural ecosystems, promoting biodiversity and soil health. Both programmes seek sustainability and food security, but from complementary perspectives.
