This soil was evidently deficient in all three of the essen- 

 tial elements of plant food, for it responded to every fer- 

 tilizer or combination of fertilizers. The largest yields and 

 the greatest jjrofits were obtained by the use of the com- 

 plete fertilizers. In a complete fertilizer 100 pounds of 

 kainit per acre was better than double that quantity. 



Likewise in 1896 this soil responded profitably to each of 

 the three usual fertilizer ingredients, the complete fertilizer 

 affording a greater profit than combinations in which any 

 one of these was wanting. 



Experiment Made by A. M. Valero, Daphne, Baldwin 



County. 



The experimenter describee the soil as follows: "Poor, 

 pine land ; stiff red clay soil, with some humus at the top ^ 

 pretty well worn out by five years' of corn culture, during 

 which time it was poorly cultivated and fertilized." 



"The severe hot weather, which has no precedent in the 

 meteorological records of this county, has proved a draw- 

 back to the growth of the plants." 



By an ovei-sight, all fertilizers were applied at a rate per 

 acre, which is 25 per cent, greater than the rate for any 

 jther experiment in this bulletin.
