2. The Amount of Fertilizing Constituents Used on Differ- 

 ent Plots. 



The amount of mixed fertilizer used on an acre is only a pai'tial 

 ecord of facts. In comparing different fertilizers, it is a matter of

 phosphoric acid and potash were applied. In the table below we 

 give this information in regard to each plot, basing the figures on 

 one acre.
