160. METABOLIC RATES: SOIL ORGANISMS 



(See next page for columns G-K of this table) 



In coluinns B D F I the following symbols are used: ;i|i = a millionth of a millionth (lO"^); u = a millionth 

 (10-6); m = a thousandth (10-3); M = million (10°). Values in columns I J K are included to indicate order 

 of magnitude of the nKtabolic activity of populations.
