In the years 1977–1980, studies were conducted on the effect of sodium used to supplement low (K = 800 mg/5 kg) and high (K = 1400 mg/5 kg) potassium doses on the content of mineral components, their accumulation in the yield and the percentage of their utilization. The study was carried out on root celery – Apium graveolens L. var. rapaceum (Mill.) and stalk celery – Apium graveolens L. var. dulce (Mill.). The results obtained in these experiments point to the following conclusions: it was found that potassium and sodium mutually limit each other's uptake. Sodium was more antagonistic towards the uptake of calcium than was potassium. However, no clearly antagonistic effect of these elements on the uptake of magnesium was determined. The accumulation of potassium and sodium by the experimental plants rose while the percentage of utilization of these elements decreased as their level in the nutrient medium increased. Sodium exerted a more distinct effect on the accumulation and utilization of other mineral elements than did potassium.
