biogeochemicalbiogeochemisch (ger.)

  • Biogeochemistry: the branch of biochemistry that deals with the relation of chemicals found in the soil to living organisms; the biological application of geochemistry. (OED 2011)

    The mass of living matter on the earth is certainly not accidental. Is it characteristic of our planet? Is it constant? This problem has been in our minds since the time of Buffon and it has received very different answers. What relations exist between the total masses of different categories of organisms? Do these relations change? How are the different categories related quantitatively in respect of nutrition? What are the quantitative relations between, say, holophytic, holozoic, saprophytic, saprozoic, herbivorous, and carnivorous organisms? Is there any relation between the total mass of a category of organisms and its rate of reproduction? Is there a constant of reproduction? The solution of these (and other) problems require new data which can only be obtained as the result of the work of a special bio-geochemical institute. Their solution will lead to new problems and will introduce numerical data into a department of science (geographical distribution of plants and animals) in which this precision has been sadly lacking.

    This is the claim advanced by Professor V.J. Vernadsky […] after investigations conducted at the Russian State Radium Institute and the Biogeochemical Laboratory.

    Life in the biogeochemical aspect is the living matter of the biosphere, that is, the total of all the living organisms present in the biosphere at a given moment

    The chemical elements, including all the essential elements of protoplasm, tend to circulate in the biosphere in characteristic paths from environment to organism and back to the environment. These more or less circular paths are known as “inorganic-organic cycles” or biogeochemical cylces.
