Soil Organic Carbon Sequestration: Experience from the ground

  1. 1. Soil organic carbon sequestration: experience from the ground Ag.Eng. Maria B (PILU) Giraudo Farmer, Consultant and Honorary President "RECSOIL: Recarbonization of global soils” Wednesday 17 June 2020, 15:00-16:30 CEST"
  2. 2. Farmer-to-Farmer Learning and Leadership
  3. 3. • Physical, Chemical and Biological fertility, the biome builds the foundation of the soil structure, cycling, delivery and absorption of nutrients, growth, crop health and yields • Efficient Use of Water, availability, surplus • Incorporation and sequestration of C, synthesis of MO, better Carbon Balance • Biodiversity ALWAYS GREEN AGRICULTURE AND THE SERVICES TO THE SYSTEM

NSAP SUMMARY CONCLUSION ✓ GAP is more similar to NE than NSAP and it is in between those situations (Growth promoters, phosphorus availability, pathogens as controllers, etc) GAP BIOlogía del Suelo y Producción Agraria Sustentable (Soil Biology and Sustainable Agricultural Production) NE A DREAM… : i) interpretation of the biological processes that occur in soil and its impact on productivity ii) the impact of soil pathogens causing and controlling diseases iii) the use of biological soil variables as indicators of environmental performance iv) the use of microorganisms with specific agronomic applications.
