Long experience has taught also in Japan that rice 
brans are an excellent fodder, but still many farmers apply 
them as a manure, probably because they are not familiar 
with any rational method of collection and application of 
farm-yard manure, and also because they frequently do not 
keep any live-stock. The manurial value of these brans is 
illustrated from the following figures, which give the com¬ 
position per mille of the air dry substance :

The ratio between nitrogen and phosphoric acid is, ac¬ 
cording to these figures, just in harmony with the demands 
of ordinary cereal and root crops, and as the brans also un¬ 
dergo decomposition in the soil with ease, their effect will 
generally be good.
