Introduction

The regeneration of agricultural soil and its transformation into a carbon sink is an innovative and sustainable strategy to combat climate change. This approach not only improves soil fertility and its ability to produce abundant crops, but also helps reduce greenhouse gas emissions by improving soil structure and its ability to retain nutrients and water. However, once crops are harvested, common agricultural practices such as burning crop residues, plowing residues into the soil, or biodigestion can actually release significant amounts of CO2 into the atmosphere at a ratio of nearly 1:1, essentially a break-even ratio between absorbed and re-emitted CO2.
“This cycle of carbon absorption and release is a critical aspect in the sustainable management of agricultural land as a carbon sink”.
