The Many Uses of So

OY BEANS have been the most im- 
portant legume in Asia for over five 
thousand years. Introduced in the United 
States over one hundred years ago, it is 
only during the last twenty-five years 
that they have become an important ag- | 
ricultural crop. Soy Beans are so adapt- 
able to different conditions and have such 
a variety of uses that they can be prof- 
itably grown on practically every North- 
west farm. 
SOY BEANS FOR HAY 
Soy Beans make excellent hay when 
properly cured. They are relatively high 
in digestible protein, higher in feeding 
value than Timothy or Clover, and about 
equal to Alfalfa. Soy Beans will produce 
good yields of rich leguminous hay on 
poor, sandy soils or on soils deficient in 
lime and so acid that Clovers cannot be 
successfully grown. As an emergency 
hay crop they can be planted as late as 
early July, but for maximum returns, — ( (jf,,7 ||

after Corn planting time. They should be — "4#/e8._ containing nih 
cut for hay as the lower leaves begin to turn yellow when 
the pods are partially filled, and should be cut early 
enough to insure plenty of good curing weather. 
Soy Bean hay should be cut and handled when dry of dew 
or rain. If the weather is favorable for hay making, the 
hay can be turned into windrows within a few hours where 
it may be left from three to five days, depending on the 
drying. When well dried out, the windrows can be tipped 
over with the end of a side delivery and allowed to dry 
on the underside for a few hours before mowing or stack- 
ing. However, if the weather should be unfavorable, it is 
advisable to put Soy Bean hay in small cocks as soon as 
possible so that the hay can go through a sweat. While 
unfavorable weather may result in discolored and poor 
looking hay, it is a fact that Soy Bean hay will take more 
punishment during curing than any other legume hay and | 
still make good feed. 
In some sections a mixture of Sudan and Soy Beans is 
recommended, planting 50 pounds of Soy Beans and 10 
pounds of Sudan per acre. 

SOIL IMPROVEMENT 
Plowed under Soy Beans furnish a greater amount of 
green manure than any other annual legume, and also add 
nitrogen to the soil through their root tubercles. While 
well inoculated Soy Beans obtain 2/3 of their nitrogen 
from the air and only 1/3 from the soil, it is a fact that 
Soy Beans do remove some plant food unless part of the 
plant is returned to the Soil as straw or manure, since 
less than 1/5 of the Soy Bean plant is below the ground.
