2. General fertilizer tests. — We shall pursue tMs study of 

 nitrate of soda still further in the following tests of the influences 

 of nitrogen, potash, and phosphorus applied separately and in 

 combination. Eight plots of six plants each, upon fairly good 

 gravelly soil which had been spariagly enriched in previous years, 

 were treated as foUoAvs, June twentieth, the yield being given in 

 the second column of figures:
