Soil Carbon Saturation - Do Soils Have a Carbon Storage Limit, and If So, What Controls It?

Explore the concept of soil carbon saturation in this informative webinar featuring Dr. Katerina Georgiou and Ph.D. candidate Maura Slocum. Delve into the question of whether soils have a finite capacity to store organic carbon and examine the factors determining soil carbon storage capacity. Learn about global-scale soil carbon storage and losses, mineral-associated carbon, and the balance between inputs and outputs. Investigate biotic and mineralogical controls across soils, estimating mineralogical capacity, and the relationship between mineral-associated organic carbon and clay + silt content. Discover management implications, challenges, and take-away messages related to soil carbon sequestration. Gain insights into C-loading in African Dark Earths and specific surface area considerations. This one-hour webinar, part of a series sponsored by the International Soil Carbon Network and various agricultural organizations, provides valuable knowledge for those interested in effective soil management practices and durable scientific concepts related to soil carbon sequestration.
