Biogeochemistry is the scientific study of the chemical, physical, geological, and biological processes and transformations that control the composition of the natural environment, including the biosphere, pedosphere, and atmosphere. It focuses on the cycles of matter and energy in Earth's systems, examining how elements and compounds are transported and transformed through various environmental compartments. Key areas of study include the biogeochemical cycles of major elements such as carbon, nitrogen, phosphorus, and sulfur, which are essential for life.

The field integrates concepts from biology, geology, chemistry, and environmental science to understand the interactions between living organisms and their physical surroundings. Biogeochemists investigate how biological activity, such as photosynthesis and respiration, influences the cycling of elements, and conversely, how geological and chemical factors, like rock weathering and atmospheric deposition, affect biological systems. This interdisciplinary approach is crucial for understanding phenomena ranging from nutrient availability in ecosystems to climate change.

Applications of biogeochemistry are wide-ranging, including environmental pollution assessment, soil fertility management, understanding marine ecosystems, and addressing global environmental challenges like climate change and ocean acidification. By studying the movement and transformation of elements, biogeochemistry provides fundamental insights into the functioning of Earth as a complex, interconnected system and helps develop strategies for sustainable resource management and environmental protection.
