PLANTS DO NOT FIX FEEE NITKOGEN 



TABLE I. Summary of the Results of Experiments made at Rothamsted to 

 determine whether Plants assimilate free Nitrogen. 



These results seem to exclude the possibility - of any 

 fixation of nitrogen by living plants, and as they had been 

 obtained with plants of three different natural orders, and both 

 without and with manure to induce an initial vigorous growth, 

 for many years the whole trend of scientific opinion was against 

 the possibility of the fixation of nitrogen by living plants.
