What does the term 'carbon sequestration' refer to in agriculture?

The term 'carbon sequestration' in agriculture refers to the process of capturing atmospheric carbon dioxide and storing it in a stable form, such as in soil or plant biomass. This process is vital in mitigating climate change, as it reduces the amount of carbon dioxide, a greenhouse gas, in the atmosphere.

In agricultural contexts, practices that enhance carbon sequestration include improved land management techniques, such as no-till farming, cover cropping, and agroforestry. These practices not only help in retaining carbon but also improve soil health and fertility, thereby benefiting crop yields.

The other terms relate to different agricultural practices. Irrigating crops involves managing water supply rather than carbon. Storage of nutrients in soil is important for plant growth but does not directly pertain to carbon. Lastly, the management of crop waste focuses on waste reduction and utilization but does not encapsulate the concept of sequestering carbon from the atmosphere.
