Plant species and varieties within species differ in their response to mineral stresses and toxicities. To achieve maximum yields, the plant and the soil must be compatible. In the past, the soil has been changed to fit the plant. In this study, the authors considered changing the plant to fit the soil, recongizing that plant species and varieties within species have specific nutrient requirements. Ten soybean (Glycine max (L.) Merr.) varieties, representing the germplasm currently used in soybean production in the United States, were subjected to Fe, Zn, and Cu stresses, and Mn and Al toxicities to determine their nutrient requirements or tolerance to mineral elements. Seven soils, which had produced the above nutrient stresses and toxicities in other crops, were used in this study. The soybean varieties showed a differential response to Fe stress by developing severe (Forrest), moderate (Hodgson), or no Fe chlorosis (Bragg). Leaves dropped from Forrest and Bragg soybean as they developed severe Mn toxicity symptoms. In contrast, Lee soybean developed only slight Mn toxicity symptoms. Most soybean varieties grew well when subjected to Zn and Cu stresses, or when grown on Al-toxic soil.
