* Mixed Minerals. 
The yields obtained in previous years on the plots (o and oo) 
‘having no manure and those having minerals alone (6a and 60) 
would seem to indicate that the soil is tolerably uniform. The 
yield of the present year on these plots is very irregular. Ploto 
is on a steeper incline than the others, and it was thought that on 
this account it might have lost more than the others by washing, 
but this season the yield was much larger than that from plot 6a, 
which was supplied with mineral fertilizers. The yield from the 
mixed mineral plots also greatly lacked in uniformity.- This 
may be due to the fact that there was considerable clover in the 
hay crop of one of these plots (64) which was harvested in June, 
and the clover stubble and roots may have increased the available 
nitrogen on this plot over that on the other mixed mineral 
plot, 6a, |
