The long-term application of ammonium nitrate and calcium chloride to unlimed soddy-podzolic soils decreased the biological value of winter rye grain. This took place through a change in the fractional composition of protein that increased the nonprotein nitrogen and gliadin nitrogen but also decreased the content of the essential amino acids. The application of these fertilizers on limed soils and especially with the simultaneous application of lime, manure, and complete mineral fertilizer increased the biological value of winter rye grain through an increase in water-soluble nitrogen concentration, albumin nitrogen, and fractions of the following essential amino acids: lysine, threonine, valine, methionine, leucine, isoleucine alanine, and tryptophan.
