This document discusses the potentials of bio-based fertilizers in managing nutrients and soil properties in saline areas. Bio-based fertilizers can help close nutrient cycles and improve soil properties by increasing soil structure and hydrophysical properties. They also help exchange and sorb salts in saline soils. The document provides a table comparing the nutrient content and additional properties of various bio-based fertilizer products. It notes bio-based fertilizers' potential to optimize nutrient release dynamics and technological innovations in production and soil management, making them suitable for improving saline soils.

3. Why bio-based fertilisers?
• Closing nutrient cycles
• Safe recovery from nutrient-rich side-streams
• Bioavailability and agronomic efficency
• Best technologies for site specific management
• Soil improvement and threat mitigation
