"The growth upon the plots which had either received no fer- 

 tilizer, or one which did not contain potash, turned yellowish, ceased 

 to grow, and produced a few imperfect ears, while upon the plots 

 which had been fertilized with a manure containing potash, it retained 

 its healthy appearance, reached its normal height, and produced a 

 liberal number of perfect ears." 



Conclusions from three years' experiments: "The beneficial in- 

 fluence of a p jtash supply on the yield of fodder upon our experimental 

 plots is in every instance unmistakable; while the application of a lib- 

 eral supply of phosphoric acid and nitrogen, either separately or com- 

 bined, on the whole, does not materially effect the annual yield, when 

 compared with the unfertilized plots." 



1888. 

 By C. a. Goessmann, Directc«. Sixth Annual Report. 



"The results of the past season confirm the conclusion presented 

 in our previous annual report. An exceptional deficiency of the soil 

 in available potash, produced by continual rotation of grasses arid 

 corn fodder, without any substantial provision for an exceptionally 

 large consumption of potash, proves still the first cause to a reduced 

 annual yield of corn fodder."

NEW YORK (Cornell Station), 1894. 

 By E. G. Lodeman. Bulletin No. 76. 



Speaking of the "shelling" of grapes, it is stated: "Probably 

 more vineyardists agree upon attributing the shelling of grapes to a 

 want of potash than they do upon any other cause advanced. There 

 are several facts which favor the theory." 



"An experiment was made by Mr. F. W. Howard, of Fredonia, NY., 

 who applied fertilizers at the rate of 200 lbs. per acre as follows: 



16 rows, applied a mixture of equal parts Muriate of Potash 

 and Bone. 

 6 rows Muriate of Potash. 

 6 rows Bone. 



6 rows Tankage. 



64 rows equal parts Tankage, Bone and Potash. 



7 rows Potash and Bone. 



4 rows, nothing. •
