Table VIll— AVERAGE RESULTS OF TWO YEARS' TESTS WITH PERU- 

 VIAN GUANO AND NITRATE OF SODA ON COTTON. 



' In 1904. 85 pounds of kainit was applied instead of 50 pounds of manure salt: but the actual 

 amount of potash in both were identical, hence the applications are taken as the same. 



- 50 pounds of the nitrate applied at planting with other materials; and the other 50 pounds of 

 nitrate applied as a side-dressing about July 1. 



^ All nitrate applied with other materials at planting. 



* 100 pounds of the nitrate applied at planting with other materials; and the other 50 pounds of 

 nitrate applied as a side-dressing about July 1. 



RESULTS OF PERUVIAN GUAKO-NITRATE OF SODA TESTS WITH COTTON. 



Results of 190 Jf. — ^At the Edgecombe farm the most profitable ap- 

 plication was one consisting of 200 pounds of acid phosphate, 85 

 pounds of kainit and 150 pounds of nitrate of soda per acre, this 

 giving a gain over cost of fertilizer applied of $57.16 per acre. 

 On this plat the nitrate application was divided and applied at the 

 rate of 100 pounds per acre with other materials just before plant- 

 ing, and the remaining quantity being applied as a side-dressing about 

 the first of July. 



The plats receiving applications of Peruvian guano were the next 

 two most profitable ones, as is shown in Table IV, where 500 and 300 

 pounds of Peruvian guano yielded respectively profits of $49.27 and 

 $47.13 per acre over cost of fertilizer. 



At the Iredell farm during this year, as seen by Table V, the ap- 

 plication producing the largest clear gain was one made up of 200 

 pounds of acid phosphate, 50 pounds of manure salt and 75 pounds 

 of dried blood per acre, and applied in the drill just before planting. 

 An application of 200 pounds of acid phosphate, 50 pounds of ma-
