Selenium (Se) is an essential nutrient for humans and animals, but is toxic at high concentrations in leaves. It is chemically similar to phosphorus (P), an essential plant macronutrient. The objective of this pot experiment was to investigate the effects of P- and Se-application rate on alfalfa gro...
