生物地球化學發表關于環境化學的生物控制或生態系統結構和功能的地球化學控制的原始和合成論文。循環被認為是生態系統中單個元素或特定種類的自然或人為化合物的循環。特別強調了元素循環的耦合相互作用。該雜志涵蓋了從分子到全球的范圍，闡明了生物地球化學循環通過空間和時間驅動模式的機制。當自然生態系統和人工生態系統的研究有助于對生物地球化學的一般理解時，就會發表這些研究。

Biogeochemistry publishes original and synthetic papers dealing with biotic controls on the chemistry of the environment, or with the geochemical control of the structure and function of ecosystems. Cycles are considered, either of individual elements or of specific classes of natural or anthropogenic compounds in ecosystems. Particular emphasis is given to coupled interactions of element cycles. The journal spans from the molecular to global scales to elucidate the mechanisms driving patterns in biogeochemical cycles through space and time. Studies on both natural and artificial ecosystems are published when they contribute to a general understanding of biogeochemistry.
