THE CONNECTICUT AGRICULTURAL 



Potash Salts. 



Analyses and Valuations. 

 [See page 60.] 



Four of the samples analyzed are high grade muriates, supply- 

 ing potash at 3.9 to 4.4 cents per pound, and seven are kainit 

 in which the potash costs from 5.8 to Y.4 cents per pound, or 6^ 

 cents on the average. 



During last spring kainit sold in N. Y. in ton lots at point of 

 shipment for cash, at from 110 to $12.60. This included bags and 

 cartage. (Bulletin XXVII, N. J. Experiment Station.) It was 

 therefore possible for farmers in the central and western parts of 

 the State at least, to get it for considerably less than |15 to $18, 

 the price charged by Connecticut dealers. 



Below are given complete analyses of the three potash fertili- 

 zers which are most used here at the present time. The analyses 

 of Muriate of Potash and Double Sulphate of Potash and Mag- 

 nesia were made by Dr. Goessmann, and published in Bulletin 

 No. 3, of the Mass. Experiment Station, pp. 5 and 6. The kainit 

 is No. 937, analyzed at this Station.

From these analyses it appears that the high grade muriate 

 consists of about 80 per cent, of potassium chloride (muriate), 16 

 per cent, of sodium chloride (salt), and 4 per cent, of Avater and 



* Mostly Chlorine.
