SOIL TESTS WITH FERTILIZERS FOR POTATOES, 



by William S. Phillips, Jr. 



Average of the nothing plots : large, 63.8 bushels; small, 21.4bushels. 



This experiment was on the acre used in a soil-test with fertilizers for 

 corn in 1889. The land lay fallow during- 1890 ; but the stakes were 

 kept up and the fertilizers were applied upon the same plots as in 

 the first year. The soil is a fine gravelly loam and previous to 1889 

 had been in grass many years without manure. It was in a low state 

 of fertility, but fairly even throughout, as shown by the total yields of 

 the nothing plots. 



The variety of potatoes was the Early Puritan ; the field was 

 planted April 29 and harvested Oct. 27-28. The experiment was 

 well carried out, and the crop carefully cultivated throughout the 

 season.
