    Abstract

    Nutrient elements applied to the soil not only give crop production but cause certain interactions with chemical constituents of the plant. Studies on four different plants, perennial ryegrass, sugar-beet, poplar and birch, demonstrated that regardless of difference in natural environment, each plant needed an optimum organic salt content as a condition to achieve optimum growth.

    The total amount of organic salts present in tissue and the relative proportion of the individual organic salts could easily be influenced by application of certain nutrient elements. The total organic salt content required for optimum growth was about 1000 m-equiv. per kg dry matter for herbage of perennial ryegrass, 3500 m-equiv. in young leaves of sugar-beet plants, 1100 m-equiv. in poplar leaves and 550 m-equiv. in birch leaves.

    The uptake of ammonium nitrogen led to decrease of organic salt content in plant tissue. This is probably not due to utilization of nitrogen in a plant but to competition between other cations and ammonium during nutrient uptake.
