SYMBIOTIC NITROGEN FIXATION ON SOYBEAN INTRODUCTION Legume plants receive nitrogen from Rhizobium which makes them possible to grow in nitrogen poor soil. In return‚ legume plants supply Rhizobium with carbohydrate‚ which is energy. This process is called nitrogen fixation‚ also known as the symbiosis of legume and Rizobium. However‚ it would be inefficient for plants in nitrogen rich soil to transfer their energy to Rhizobium in exchange of nitrogen when sufficient amount of nitrogen is present

Transportation is the largest single source of air pollution Today’s on-road vehicles produce over a third of the carbon monoxide and nitrogen oxides in our atmosphere and over twenty percent of the global warming pollution. This air pollution carries significant risks for human health and the environment. Through clean vehicle and fuel technologies‚ we can significantly reduce air pollution from our cars and trucks‚ while cutting projected U.S. oil use in half within the next 20 years. Cars and
