Some interesting results are shown from the expertments on Field 
F, in 1903, which can be a little better understood on account of the 
data obtained from the same plats for the next two years. 
The difference in effect of the fertilizers and manures is greater 
than could reasonably be expected, when it is seen that this soil with¬ 
out manure or fertilizer was able to produce about 21.5 tons per acre.

The effect of the excessive quantity of manure,.Plat 1, was not 
as injurious to the quality of the beet as might be expected, only about 
two per cent less sugar and four points less in purity than the plats 
yielding less. The yield was also about a ton less than the other 
manured plats, while the beets although larger were of poorer shape. 
The phosphoric acid used alone from bone meal and Basic slag, 
Plats 7 and 8, had very little if any effect on increasing the yield, 
although the Basic slag produced a ton more beets than the bone meal, 
which alone had practically no effect on the yield of beets. Used 
with nitrate of soda on Plat 5, we may presume it would be equally 
ineffective. The highest yields of any of the fertilizers was from the 
Plats 4 and 5 where nitrate of soda was used at the rate of 150 pounds 
per acre. This is a little more than the result from the plat of thirty 
tons manure or 4.1 tons more than the unfertilized plat. The 
nitrate of soda and fifteen tons of manure together, could not evi¬ 
dently increase the yield as 25.6 tons per acre was the limit of which 
this soil seemed capable. 
Although the highest yield was from Plat 4, with nitrate alone, this 
is probably a trifle more than should be due to the nitrate, as a study 
of residual effects during the next two years seems to show that the 
soil conditions of this plat were slightly more favorable than those ad¬ 
jacent. 
The results from the two complete fertilizers, Plats 9 and 10, are 
disappointing in yield. The highest yield was obtained from th6 one 
containing the larger quantity of nitrate of soda, 100 pounds, produ-
