Osmotic tension was found to reduce nitrate production and CO 2 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 CO 2 evolution is much more tolerant of osmotic stress and shows no definite individual salt effects.
