Abstract
Abstract Sulfur deficiency decreased growth and concentrations of nonsoluble N and soluble protein N, increased concentrations of nonprotein N and free amino acids, and had little effect on nitrate N in soybean seedlings. Amide N concentration increased and nitrate reductase activity decreased only in S‐deficient nonnodulated seedlings grown with nitrate N source. Ammonia N concentration increased only in S‐deficient nodulated seedlings grown without an available N source. Nodule hemoglobin concentration was affected little, but nodule quantity and total N 2 fixed were decreased markedly by S deficiency. The capacity of soybean seedlings to fix N 2 was less than their ability to utilize nitrate N.
