NMSU: Nitrogen Fixation By Legumes
When nodules are young and not yet fixing nitrogen they are usually white or gray inside As nodules grow in size they gradually turn pink or reddish in color indicating nitrogen fixation has started (Figure 2) The pink or red color is caused by leghemoglobin (similar to hemoglobin in blood) that controls oxygen flow to the bacteria (Figure 2)

Ammonia Synthesis for Fertilizer Production
synthesis is the Haber-Bosch process created by Fritz Haber in 1905 and developed for industry by Carl Bosch in 1910 The overall process synthesizes ammonia from molecular nitrogen and hydrogen by feeding the reactants over iron catalysts at a high pressure and temperature requiring bulky well-insulated reactors to house the process

THe Haber Process
The Haber Process is a good example of the use of equilibrium principles The equation for the reversible reaction is : N2(g) + 3H2(g) -- 2NH3(g) + 92 kJ Because raising the temperature will increase the speed of both the forward and reverse reactions a high temperature should bring the reaction to equilibrium rapidly
