Excerpt from Toxic Effect of Salts on Plants A few investigations have been made regarding the action or single salts on plants, but in the majority of cases the object has been to determine the limit of endurance or the highest concentration at which certain plants could live in the pure salt solutions. These concentrations varied with the salts used and one could not from the tabulated results tell the difference in growth or plants in the various salts of the same molecular solution, nor would it be safe to asswne this ...

Excerpt from Toxic Effect of Salts on Plants A few investigations have been made regarding the action or single salts on plants, but in the majority of cases the object has been to determine the limit of endurance or the highest concentration at which certain plants could live in the pure salt solutions. These concentrations varied with the salts used and one could not from the tabulated results tell the difference in growth or plants in the various salts of the same molecular solution, nor would it be safe to asswne this difference to vary uniformly in all concentrations. In experiments on Lunularia, not yet publishedgthe reverse was found to be true, as the comparative dense of toxity of certain solutions at one concentration might be entirely different at another. Again, time was found to be a very important factor in changing this relation, so that experiments lasting only a short period could not be considered. Conclusive. The work done by previous investiga tors differs so greatly in method and the results are so scattered that no comparison with my results is possible.
