Interpretive Summary: Mineral undernourishment is of concern throughout the world, and plant-derived foods are considered a major dietary source contributing to adequate daily mineral intake. Soybeans and soy ingredients are consumed daily by humans and animals. In this study, we demonstrate the climate thresholds for optimum weather conditions (OWC) that optimize nutritional mineral content in soybeans. For example, the OWC maximizing Ca, Mg and Mn were defined by maximum and minimum daily air temperatures over 30.1°C and 17.1°C respectively. Soil features, mainly soil pH, and soybean-genotypes affected micronutrients concentrations in soybeans. Mo and Se were significantly positively correlated with soil pH. Taken together, the environment affected the mineral concentration in soybeans contributing to the nutritional and safety features of soybeans and soy foods. The information will lead to a better understanding of the linkage between agricultural production and human health, and will be useful for scientists, soybean producers and health-care professionals who are interested in plant-derived foods.
