Is organic carbon stock affected by core ring volume used for bulk density measurement?

Puntos clave

• Organic carbon stock varies significantly with different core ring volumes used for bulk density measurement, impacting accuracy.
• The study shows that using various core ring volumes results in fluctuations in organic carbon estimates by 15% or more.
• Soil samples were collected under standardized conditions to analyze variations in carbon stock based on ring volume.
• Such findings highlight the need for standardized methodologies in bulk density measurements for reliable carbon stock assessment.
