Biofortification of Spring Barley Grain with Microelements through Sulfur Fertilization by Bożena Barczak, Magdalena Jastrzębska, Marta K. Kostrzewska

“…It was demonstrated that, in the fertilization of spring barley, supplementation of NPK with sulphur can be regarded as an agronobmic method of biofortification of grain with micronutrients because it beneficially affects the content of manganese, iron, zinc, and copper in the grain. An increase in the content of these micronutrients was found in the grain of plants fertilized with sulphur in comparison to plants that were not fertilized with this nutrient in each of the growing seasons. …”
