✦ Synopsis

The increase of inorganic nitrogen subsequent to the addition of organic matter was investigated in replicate lake-water aliquots . Two experiments used freshly killed bacteria as the organic addition . In both, inorganic nitrogen in the water column increased only after a lag period following the organic addition, and only if the amount of organic matter added exceeded a threshold value . Two other experiments used freshly killed algae as the organic addition ; in these, neither the lag period nor the threshold value were seen . A qualitative explanation for these observations is offered .
