The effects of sodium chloride on some turf plants and soils

The effect of phosphorus and sodium chloride on some common turf plants and soils was studied in a series of greenhouse and laboratory experiments. Phosphorus stimulated the growth of the plants, but sodium chloride in the concentrations used was apparently toxic in some cases and stimulative in others. The toxicity of the sodium chloride was decreased somewhat by the phosphoric acid. Metropolitan bent grass was more tolerant to sodium chloride than Kentucky bluegrass, seaside bent grass, Bermuda grass, or Dutch white clover. Highly significant differences in the effect of phosphorus and sodium chloride on the growth of the different plants were obtained. The total exchangeable base content of the soil was decreased by the treatment with sodium chloride. The results indicate that sodium chloride alone or in combination with phosphate fertilizers may be used on sandy soils for metropolitan and seaside bent grass. However, these experiments are preliminary in nature and further work with nitrogen and potassium fertilizers applied along with salt and on different soil types is necessary to permit of broader conclusions and such work would certainly be very desirable.
