Soil carbon sequestration has emerged as an innovative approach that may offer a low-risk and an efficient way to mitigate climate change and replenish soil fertility. In various agricultural production systems, byproducts are produced in significant amounts from crop residues such as pecan shells (PC), peanut shells (PS), and cotton gin (CG) that can be used to produce biochar and applied to agricultural soil first to sequester C and second to enhance plant growth by supplying and retaining nutrients, improving soil physical and biological properties.
