A Study of Colorado Wheat

for the soft wheat flours, which fall below this yield. The minimum 
yield that we have found is 272 loaves. This result is in harmony with 
the statements often made relative to our flours, but it no longer repre¬ 
sents the facts. The check flours that we used as criteria of excellence 
yielded from 280 to 296 loaves per barrel. 
In volume, our flours yielded from 100 grams of flour, from 455 
to 511 c.c. mostly, however, from 470 to 500 c.c. The samples pre¬ 
pared from soft wheats show their deficiency in this as well as in other 
respects. Our check samples ranged from 475 to 514 c.c. for each 
100 grams of flour used. It is evident that our flours compare favor¬ 
ably with the best on the market and can be produced of uniform qual¬ 
ity if the desire to do so is strong enough. This might be different in 
the case of small mills receiving all kinds of wheat, varying from good,, 
hard wheat, either spring or winter wheat, to very soft, indiffereiu 
wheat. 
We have given the results on such samples as we could obtain. 
They represent different localities, the products of different mills and 
the skill of different millers. These results are in harmony with the 
‘'onclusions that we have elsewhere drawn based wholly upon analytical 
results, i.e., that our wheats are not inferior in composition or in bread¬ 
making qualities to the same varieties grown elsewhere, but that on 
the contrary our conditions produce excellent wheats when the soil is 
properly cultivated and advisedly fertilized. 
SUMMARY 
The character of the grain produced depends upon the relative 
supply of the respective plant foods. 
The important factor in our conditions is the ratio of the nitric 
nitrogen to the available potassium. 
Organic nitrogen, as in farmyard manure, is not nitrified rapidly 
enough to affect the composition and physical properties of wheat. 
Phosphorus does not produce in our soils the effects usually as¬ 
cribed to it. 
Potassium in excessive ratio to nitric nitrogen produces meally 
wheat. 
Excessive irrigation does not produce meally or soft wheat. 
Frequent rainfall, accompanied by heavy dews, reduces the ash 
and nitrogen content of the plant.
