_ Nitrate of boda y tankage and barnyard manure were used 



as carriers of the phosphoric acid, potash and Nitrogen. 

 The same variety of seed, Original Kleinwanzlebener, was 

 planted on all the plots. 



Results on Black Sand. 



More satisfactory results were obtained from the ferti- 

 lizer tests on black sand, the increase of yield of the 

 fertilized plots over the unfertilized being very decided. The 

 test included a series of five plots, the first and fourth 

 being left unfertilized. The results shown in Table VII, 

 page 72, set forth the interesting facts that acid phosphate 

 alone increased the yield 260 pounds to the acre ; the com- 

 bination of phosphoric acid and potash shows better results, 

 by increasing the yield 3,980 pounds per acre; the combi- 

 nation of phosphoric acid, potash and Nitrogen shows the 

 best results, giving an increase of 8,070 pounds per acre.
