Best results are secured from fertilizer by applying broadcast when 

 fitting seed bed. An amount of more than 150 lbs. per acre, drilled in 

 the rows, may cause concentration of corn roots close under the hill, 

 or injure sprouting seed, thus leaving the crop in poor condition to with- 

 stand periods of drought. On light soil, when planting late under dry 

 conditions, the use of not more than half this amount may be advisable.^

 ported by Professor V. M. Shoesmith in the annual report of the State 

 Board of Agriculture for 1917, Farm Crops Division : 



20. Acid Phosphate, other commercial fertilizers, or lime are most conveniently applied 

 at time of fitting the seed bed. An application of from 200 to 250 pounds of Acid Phosphate 

 usually gives marked increase in yields of corn and hastens maturity.
