with what has been said before on that subject, an increase in 

 potash (kali) appears in all cases as only advisable. 



EXPERIENCE WITH POTASH IN THE 

 UNITED STATES. 



It would be erroneous to believe that the value of potash has 

 been recognized only on the other side. The experiments made 

 at the various experiment stations here bear out the assertions 

 of the German Agricultural Chemists on that subject. So we 

 read, for instance, in the bulletins issued by the experiment 

 station in Kentucky, "That the results of the experiments 

 regarding potash are so marked as to strongly indicate that for 

 corn, potash is the fertilizer needed on the soil of the experi- 

 ment station," and the report continues to say, "that this holds 

 true also for potatoes, that the results on hemp and tobacco 

 prove the same to apply to these crops, and that there are strong 

 indications that wheat will likewise be benefitted by the appli- 

 cation of potash. Therefore," it continues to say, "it would 

 seem that the soils of like character in the Blue Grass region 

 would be benefitted by potash fertilizers." 



Very striking results have been obtained in the State of New 

 Jersey by the use of potash salts. 



In the Second Annual Report of Texas Agricultural Experi- 

 ment Station, we read on page 80, "Of the fertilizers, kainit 

 has proved the most beneficial. Many correspondents in other 

 cotton States mention kainit as valuable in keeping cotton root- 

 rot in check." 



But of singular importance appears also what Dr. Dabney, as 

 Director of the North Carolina Experiment Station, wrote as 

 long ago as 1882 with reference to kainit. A comparison of 

 what he says on that subject, with what Prof. Wagner has more 

 recently established, proves conclusively, that the investigations 

 carried on by Dr. Dabney corroborate in full those of Prof. 

 Wagner. Referring to what Schultz and Rimpau had accom- 

 plished by rational potash fertilization, Dr. Dabney says: "A 

 large portion of all the South Atlantic States are covered with 

 just such lands, while nearly all the arable land in the eastern 

 portions of these States are exactly of the same character which
