Artificial Manures for Stcedes. 



the Amount of Ash and Nitrogen in Swedes of 

 Experimental Plots. 



I do not think the variations indicated by these determinations 

 are sufficiently great to entitle us to say that the swedes of one 

 plot were more nutritious than those of another. 



On the whole these analyses show that the different fertilizers 

 employed in the experimental trials did not affect the composi- 

 tion of the swedes in any material degree ; consequently the 

 question as to the comparative economy of using superphosphate 

 of lime in preference to all the other manures employed in the 

 experimental trials remains simple, and the general conclusions 

 to which these experiments have led are not affected by any 

 differences in the nutritive value of the roots.
