TI - Studies on sulfur in alfalfa: Sulfur content of alfalfa grown on a low-sulfur soil more than doubled by application of gypsum in tests near Delhi JF - California Agriculture JO - Calif Agr Y1 - 1955/06/01 VL - 9 IS - 6 SP - 9 EP - 14 PB - University of California Agriculture and Nature Resources SN - 0008-0845 UR - http://www.ucanr.edu/sites/calagjournal/archive/?article=ca.v009n06p9 AB - Alfalfa protein is relatively low in the sulfur-containing amino acids, and the alfalfa's nutritive value may thereby be limited. This has been indicated at several laboratories in biological assays—feeding tests with small animals. Increasing the sulfur content of alfalfa, therefore, may improve its value as a feed.
