Field C, Chemical Fertilizers and Manure for jNIarket- 



Garden Crops. 



On this field during the past twenty-six years we have grown 

 practically all the market-garden crops common in this State. 

 The fertilizer schedule is so arranged that we are able to study 

 the effect of manure used alone and with different combina- 

 tions of chemicals, and we are also able to compare, as sources 

 of nitrogen, sulfate of ammonia, nitrate of soda and dried 

 blood; and as sources of potash, muriate and high-grade sul- 

 fate. 



The unsatisfactory results obtained from time to time on the 

 sulfate of ammonia plots led to the belief that an application 

 of lime would improve conditions. Accordingly, in 1911 all 

 plots were divided, and half of each plot received an application 

 of marl at the rate of 1 ton per acre. The same half of each 

 plot also received an application of hydrated lime at the rate 

 oi \}/2 tons per acre in 1916. The following table shows the 

 results obtained this year due to liming with the two crops 

 onions and beets: —
