Sulfur and Nitrogen Content of Alfalfa Herbage During Growth1
- F. V. Pumphrey and
- D. P. Moore2
Sulfur fertilization increased the sulfur and nitrogen content and yield of alfalfa herbage. Percent sulfur was highest in the young growth and dedlned at a near linear rate for both deficient and nondeficient plants. The use of a critical level of sulfur in alfalfa herbage needs to be associated with a definite stage of growth. The nitrogen to sulfur ratio in the herbage was nearly constant at all stages of growth and was much narrower in the nondeficient than in sulfur-deficient herbage.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
