2. The quality of the grain was superior on all plots where 

 potash had been applied. The kernels were larger, plumper and of 

 better color than on other plots. 



3. That rye apparently cannot as readily as other cultivated 

 plants appropriate the potash of the soil, has been noticed by other 

 observers. This accounts for the beneficial effects of the applica- 

 tion of this element. 



Our conclusions for rye stated with reference to the questions pro- 

 posed are :. — 



1. Rye shows a more general dependence upon applied fertilizers 

 than the other crops under experiment. The difference in the de- 

 gree of effectiveness of the elements applied (nitrogen, phosphoric 

 acid and potash) is not great. 



2. The same fertilizers are offered in Massachusetts, as a rule, 

 under the name of " grain " ftrtilizers, both for oats and rye. This 

 is not warranted by the facts brought out concerning the two crops. 

 Nitrogen should be most piomiuent in fertilizers for oats ; while for 

 rye, the fertilizer must be richer in potash. 



3. The results of our experiment do not encourage the belief that 

 one-sided phosphate manuring for rye will give most profitable 

 results. 



WitJi White Mustard, Cabbage and Sicedish Tiirnips: — The white 

 mustard was sown as a catch crop, after rye, in 1895 ; the cabbages 

 and turnips were grown oa similar soil, in 1896. 



1. Phosphoric acid in the form of dissolved bone-black benefited 

 all these crops more largely than either nitrogen or potash. 



2. The potash when used in connection with phosphoric acid was 

 also very beneficial to the cabbages and turnips. 



Our conclusio-ns are : — 



1. These crops (all belonging to the same family) are markedly 

 different in their requirements from any of the others experimented 

 with — responding in highest degree to an application of phosphate, 

 which none of the otheis have done. 



2. There appear to be but few "special" fertilizers upon our 

 markets for these crops. 



3. The use of phosphates to supplement farm manures for these 

 crops promises to be profitable.
