Influence of Salts on Ammonium Oxidation and Carbon Dioxide Evolution from Soil1

Osmotic tension was found to reduce nitrate production and CO2 evolution from soil in a linear manner. This is essentially the result which would have been predicted using principles derived from studies on the influence of salts on the growth of higher plants. Nitrification showed the influence of individual salt species, with NaCl being the most toxic. Total microbial activity, as measured by CO2 evolution is much more tolerant of osmotic stress and shows no definite individual salt effects.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
