  The amount of easilysoluble potash obtained from the soil  
d p  of itheiplots that received no potash is not as small as was ,  
e E expected, nor that from the ones that received potash fertilizers `  
Q j as large, though the difference between the soil which received J  
) 5 potash salts and that which received none is quite marked. It ` — 0  
,f   was to be expected that the soil of Plot 5 would contain less  
h 3 available potash than that of 7Plot»6. The difference actually  
d  _ shown is very slight. The nitrogenous fertilizer used on Plots  
;S _   5 and 9 appears not to_ have affected the percentage of nitrogen
