The other plots in the lie Id received aii application of 

 materials practically the same in kind and quantity as have 

 been recommended in Bulletin No. 58 for corn on soils poor 

 in organic matter. The principal difference between the 

 manuring of these plots and the others is that they receive 

 slightly more nitrogen, nuich less phos})horic acid and con- 

 sidera])ly more })otash. The materials supplied to the sev- 

 eral plots are shown in the following table : —

The variety of corn grown this year was Sibley's Pride of 

 the North. The growth was vigorous and healthy, and un- 

 affected, so far as could be seen, by any abnormal conditions. 

 The yields were as follows : —

Average Yield per Acre.

It will be noticed that the yield of grain on the "special" 

 fertilizer exceeds that on the fertilizer richer in potash, the
