Several experiments had been made previously on this 

 farm. That of 1898 showed acid phosphate to be the 

 •most valuable single fertilizer, but that both kainit and 

 cotton seed meal afforded such an increase as to make 

 the complete fertilizer — ^which contained all three — the 

 most profitable of all applications. 



In 1897, when drought prevailed, only cotton seed 

 meal was very effective. 



Clearly a complete fertilizer is profitable on this soil, 

 which lends itself readily to intensive farming.
