As the amount of CO2 in the atmosphere continues to rise, soybean plants will likely exhibit enhanced rates of photosynthesis, which will lead to greater synthesis of starch and other carbohydrates for supporting increased growth and development. In addition, if the atmospheric ozone level continues to rise, the rising CO2 content of the air will likely protect soybeans and other crops from the adverse effects of ozone that reduce productivity, growth, and yield.
