PART IV. 



RESULTS OF OFFICIAL FERTILIZER 

 EXPERIMENTS. 



Our experiment stations are now at work finding out 

 what forms and quantities of fertilizers will best supply the 

 soils and crops at the lowest cost. Although each station 

 works upon the soils and crops of its own region, the 

 results of such work are often of great value to the farmers 

 of other states. Thus, the results with fertilizers for cotton 

 and remedies for cotton blight are useful to the planters of 

 all cotton growing states. The results obtained at the 

 West Virginia and Connecticut stations with fertilizers 

 upon potatoes may apply also in New York and Ohio. 

 What is found as the result of a certain kind of fertilizer 

 upon corn at the Kentucky and Tennessee stations may be 

 useful to farmers in Virginia and Illinois. 



The results of experiments with fertilizers are pub- 

 lished in many of the experiment station "bulletins." It is 

 important that the practical information gained in the 

 experimental fields of the stations should be known to the 

 farmers, not only of the states in which the tests were 

 made, but to the farmers of other states. For this purpose 

 we have selected from experiment station bulletins some 

 results obtained with fertilizers upon the most common z nc 

 staple crops. The facts and illustrations here given are Ul 

 taken from the official bulletins and records.
