生物地球化学发表关于环境化学的生物控制或生态系统结构和功能的地球化学控制的原始和合成论文。循环被认为是生态系统中单个元素或特定种类的自然或人为化合物的循环。特别强调了元素循环的耦合相互作用。该杂志涵盖了从分子到全球的范围，阐明了生物地球化学循环通过空间和时间驱动模式的机制。当自然生态系统和人工生态系统的研究有助于对生物地球化学的一般理解时，就会发表这些研究。
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.
