The applications of the various chemicals were calculated at the rate of 
320 pounds of sodium nitrate to the acre. The nitrogen carriers were 
used in such proportions as to give an amount of nitrogen to the acre 
equal to that supplied by the application of sodium nitrate. The other 
elements were applied in such proportions as to give amounts to the acre 
equal to those supplied by the nitrogen carriers. The acids were used in 
amounts which were chemical equivalents of their respective neutral 
salts. The exact quantities of the chemicals used to the plot are shown 
in the foregoing table. The chemicals were applied in solution only, and 
25 gallons of water were used in each case. The experiment was con¬ 
ducted in duplicate (series A and series B). An average of the results
