Summary The sulfur nutrition of Italian ryegrass was studied by a nutrient solution technique. Sulfur-deficient plants were stunted and erect in appearance; upper leaves were an abnormal yellow-green. Shoot growth was affected more than root growth by changes in the amount of S supplied. The sulfate-S values in all plant parts were very low, less than 500 ppm, dry basis. Most of the sulfate-S absorbed was converted to organic-S. Organic-S and total-S determinations are not recommended for diagnostic purposes. Sulfate-S in blade 1 should be used to diagnose the S status of Italian ryegrass. The critical level of S for growth of the ryegrass is about 100 ppm sulfate-S in blade 1 tissue, dry basis. Concentrations below this value indicate S-deficiency for plant growth.
