"The difference is very easily seen, and we are forced to conclude 

 that. our fertilizers are deficient in potash." 



NEW JERSEY. 1883. 



By John Voqrhees, South Branch, Somerset Co, Annual Report 

 ' for 1883, page 52. Soil — Red shale loam. 



"Plots on which potash was used, both alone and in combination 



with phosphoric acid and nitrogen, show an enormous increase in yield. 



. Plot 4 (potash alone) shows that an outlay of $3.25 per acre 



increased the yield of corn 29.5 bushels, and stalks 1,000 lbs., a net 



profit of $16.00. 



"The application of potash yields large profits in every case; phos- 

 phoric acid was profitable in one case only, and that when in combina- 

 tion with potash; nitrogen does not increase the yield in any case. 



"The quality of corn was also favorably influenced by the use of 

 potash, a fact indicated by the increase in yield of soft corn, which in 

 every case varied considerably. These results confirm those obtained 

 last year by Rev. Henry P. Thompson, of Readington, whose farm is 

 situated about three miles northeast of Southbrook, 



"Both experiments show that large profits were derived from the 

 use of potash and phosphoric acid, though the effect of potash alone is 

 more striking in the case of Mr. Voorhees, the soil of this section 

 being mostly red shale loam. And it is more than probable that these 

 experiments by Mr. Thompson and Mr. Voorhees may serve as guides 

 in the use of fertilizers to all farmers upon similar soils."

"Muriate of potash, both alone and in combination, had a notice- 

 able effect upon both grain and stalks." 



By J. W. Dalrymple, Hopewell River, Mercer Co. P'ifth Annual 

 Report. Soil — Red shale. 



"Potash and its combinations being relatively cheaper, give 



largest profits."

 Report. 

 "Of all elements, potash influences stalk development most favor- 

 ably, and when used alone, its yields excel those from its combinations.'
