土壤中的碳含量是大气中的两倍，大多数土壤碳来自最近的光合作用，光合作用将碳带入根系结构，并通过分泌物进一步进入地下储存。然而，许多天然作物和大多数农业作物的根仅延伸到地下约1米处。是什么决定了地下各种形式的碳的寿命还没有得到很好的理解，因此了解这些过程是优化它们以增强碳封存的关键。大多数土壤（尤其是底土）的有机碳远未饱和，计算表明，可能进一步被隔离的碳量（）实际上非常大。因此，培育具有理想的地下碳螯合特性的作物，并在其相关环境中利用针对个别物种优化的伴随农艺措施，是重要的目标。这些带来了与改善土壤结构和其他养分和水的使用有关的额外好处。
The soil holds twice as much carbon as does the atmosphere, and most soil carbon is derived from recent photosynthesis that takes carbon into root structures and further into below-ground storage via exudates therefrom. Nonetheless, many natural and most agricultural crops have roots that extend only to about 1 m below ground. What determines the lifetime of below-ground C in various forms is not well understood, and understanding these processes is therefore key to optimising them for enhanced C sequestration. Most soils (and especially subsoils) are very far from being saturated with organic carbon, and calculations show that the amounts of C that might further be sequestered () are actually very great. Breeding crops with desirable below-ground C sequestration traits, and exploiting attendant agronomic practices optimised for individual species in their relevant environments, are therefore important goals. These bring additional benefits related to improvements in soil structure and in the usage of other nutrients and water.
