 VARIOUS CROPS. 



QUOTED FROM EXPERIMENT STATION BULLETINS. 



The Proper Composition of Fertilizers. 



FLORIDA. 1893. 



Fertilizers — By A. A. Persons. Bulletin No. 22, page 16. 



**From chemical analyses of the soils of various sections of Florida 

 made in this laboratory, it is made apparent that the soils of this State 

 are universally more deficient in potash than any other element, while 

 phosphoric acid is more generally diffused throughout the soil than 

 either of the others. This fact, taken into consideration along with 

 the other fact that, generally speaking, the character of the crops 

 grown throughout the State is such as requires a predominance of 

 both potash and nitrogen, it would seem, to say the least, that a 

 majority oi fertilizer combinations put annually upon our markets for 

 sale are ill adapted to fruit and vegetable growing. The writer is of the 

 opinion that, as a general rule, it would be well for our manufacturers 

 to reverse the proportions of many of the fertilizer formulas that they 

 are daily commending as admirably adapted to fruit-growing, and 

 have the constituents proportioned about as follows: 



Phosphoric Acid 5 to 6 per cent. 



Potash 10 to 12 •• 



Nitrogen 6 to 8 " 



"It is confidently believed that a mixture compounded in accord- 

 ance with the above formula will, in a great majority of instances, 

 yield results far more favorable in the case of fruit crops than the 

 ordinary routine formula that our fruit-growers have been accustomed 

 to use for years,
