Directions for the Application of the Fertilizers and 



Records to be Made. 



Since so many applications have been made for fertilizers 

 to be used in the " Field Experiments," we have limited the 

 size of plats to be experimented upon to -^ of an acre each. 

 We have sent you by freight one large sack containing ten 

 small sacks, each tagged so that you can tell what kind and how 

 much fertilizer each small sack contains. 



Pay no attention whatever to any printing that may be upon 

 the sacks, but give strict attention to the tags that are tied to the 

 bags. The contents of the small sacks are to be applied to the 

 plats as follows : 



On Plat K put contents of one sack containing 10 pounds Muriate of Potash. 



On Plat N put contents of one sack containing 10 pounds Nitrate of Soda. 



On Plat KN put contents of one sack containing 10 pounds Muriate of Potash, 

 also contents of one sack containing 10 pounds Nitrate of Soda. 



On Plat P put contents of one sack containing 20 pounds Superphosphate. 



On Plat KP put contents of sack containing a mixture of 10 pounds Muriate 

 of Potash and 20 pounds Superphosphate. 



On Plat NKP put contents of one sack containing 10 pounds Nitrate of Soda, 

 also contents of sack containing a mixture of 10 pounds Muriate of 

 Potash and 20 pounds Superphosphate. 



On Plat NP put contents of one sack containing 10 pounds Nitrate of Soda,
