Experiment Made at Cullman: in. 1904. 



This experiment was conducted by Mr. Feirtag for Mr. L_. 

 A. Fealy. The land is described as very poor and the test 

 as entirely fair. The soil is not described but was probably 

 the characteristic sandy soil of that region. For yields and 

 increase see table on page 36. The largest increase and 

 the greatest profit were obtained on plot 5 from a mixture- 

 of acid phosphate and cotton seed meal, the net profit there- 

 being 17.43 per acre.
