growing on each of the samples, and made a botanical analysis of 

 them. Following are the results : 



COMPOSITION OF HERBAGE (HAY). 



"On Plot 1 there was an abundance of plantain and field wood- 

 rush, while the grasses (chiefly bent and fescues) were poor and 

 stunted, with no seed stalks, and the legumes were represented only 

 by a little birdsfoot trefoil and white clover. Plot 7 had an abund- 

 ant sole of white clover herbage, with some red clover and other 

 legumes. The grasses were bent and fescues, with some Yorkshire 

 fog and cocksfoot, the last being better developed here than on. any 

 other plot. There was much less white clover on Plot 8, and the 

 plants were weak. Sweet vernal and crested dogstail were present, 

 in addition to the grasses on the last plot, while plantain and yellow 

 rattle were the principal weeds. On Plot 9 white clover was weaker 

 than on Plot 8; fescues and bent were the chief grasses, with some 

 sweet vernal, while plantain and field woodrush were the principal 

 weeds. 

 NITROGEN IN THE HERBAGE, ROOTS AND SOIL OF DIFFERENT PLOTS. 



"The foregoing figures show that the soil is practically no richer 

 in nitrogen on Plots 8 and 9, after the continuous application of 

 either nitrate of soda or sulphate of ammonia for thirteen years,
