Mr. G. A. Glover's Experiment at Naples. 



DESCRIPTION OF SOIL. 



The land selected for this experiment produced about a ton and 

 a half of hay to the acre nine years ago ; has been in pasture 

 since, the cattle being housed at night. Soil heavy loam with hard 

 pan subsoil.

In these experiments it will be fair to attribute the gain in crops 

 on the plots to which the phosphates were applied, over those on 

 which sulphate of ammonia and muriate of potash alone were 

 used, to the phosphoric acid taken up by the crop from the 

 phosphatic fertilizing material. 



In Mr. Leland's experiment, the highest yield per acre of the 

 plots to which sulphate of ammonia and muriate of potash alone 

 were supplied, was 22 bushels. Taking this as the measure of 

 what the soil was able to produce under the conditions of the 

 experiment when only sulphate of ammonia and muriate of potash 

 were applied, we have on the plots on which fine ground South 

 Carolina rock was used in addition to sulphate of ammonia and
