Tplants, vitiated tlie experiment. The results suggest that a 

 mixture of cotton seed meal and acid phosphate was suffi- 

 •cient. Cowpeas in corn or after oats, and grazed, grew on 

 'the land in each of two years preceding the experiment. 



Mr. W. A. Candler, Clanton, Chilton county, made the 

 •experiment on land where the preceding winter he had plow- 

 ed in a very rank growth of cowpea vines, affording condi- 

 tions unsuitable for a test of commercial fertilizers. 



At Wetumpka, the test was made on the farm of the 

 District Agricultural Schools with conflicting results both 

 in 1902 and 1903. 



At Greensboro the tests were made by T. K. Jones, 1 1-2 



miles south of town on poor red upland, originally' covered 



■with hardwood. In 1902 manure was accidentally added to 



•certain plots, and in 1904 the growth of grass ruined the 



'experiment. 



Four miles north of Union Springs Mr. N. Gachet made 

 a test on light, reddish loam with red clay subsoil, where 

 "the original growth had been hardwood. Variations in 

 the stand destroyed the value of the experiment. 



The test at Carson, Washington county, was consigned to 

 ^Ir. R. D. Palmer. It was made on gray upland, pine land 

 "with vellow clav subsoil, two miles north of Carson. The 

 results are somewhat conflicting. 



For the Geneva experiment, see page 66.
