The chief object of these local fertilizer experiments or soil 

 tests has been to ascertain the best fertilizer or combination of 

 fertilizers for cotton, growing on each cjf the principal soils of 

 the northern half of Alabama. 



The results recorded in this bulletin were obtained in fer- 

 tilizer experiments conducted with the funds provided by the 

 Legislature of Alabama in February, 1911. 



This bulletin deals only with fertilizer experiments carried 

 to a conclusion in 1911 in the northern half of the State. For 

 convenience the counties grouped together in this bulletin are 

 those lying wholly north of the Central Prairie or Lime Region 

 of Central Alabama. 



The results of fertilizer experiments made in the counties 

 lying wholly or partly south of the Central Prairie Region ap- 

 peared in Rulletin No. 160, issued by this Station in December, 

 1911. 



L-ocal fertilizer tests constitute only one of many lines of 

 experiments instituted in 1911 by the Alabama Experiment 

 Station with the support of state funds, none of which were 

 available for experimental work prior to the present year. 



Local fertilizer experiments as now conducted are made 

 on the farnis of farmers especially recommended as being men 

 likely to take the necessary pains to secure accurate results. 

 These experiments, located all over the State, are visited and 

 supervised by representatives of the Experiment Station, who 

 are expected to select and measure ,thc land, make periodic 

 visits, and take notes on the progress gmd. results of the experi- 

 ment, and, so far .as practicable, assist in harvesting the crop. 

 ■However, the late date at which this work was begun in 1911, 

 the fact that many farmers had already fertilized their most 

 suitable land before being invited to make the^e experiments, 

 and the necessary delay in securing tlif: services of. the men
