Animal Food Values of Certain
Crops
A. P. r., Cuthbert, Ca, writes:
Please give me the relative feed
and other values of soy beans,
velvet beans and mung beans;
also time to plant and amount
of seed per acre. L want to plant
some in corn and also broadcast
some.
Soy bean hay contains about GA
per cent of dry matter, Ill per cent
of digestible protein, 1921 per cent
Of kigestih!e carbohydrates, and IL
per CANT af digestible fat. Velvet
bean hay contains about 1928 per
cent of digestible dry matter, IL per
cent Of digestible protein, 40.S per
cent of digestible carbohydrates, and
Ia per cent of digestible fat. / do
not know that any digestive tests
have been made with mung beans.
If so, 1 am unable to locate them,
but when this crop is nearly mature,
it contains 81 per cent of protein,
9.S per cent of fiber, per cent OF
nitrogen free extract, and IL per
cent of fat. 1t runs much lower in
ash than soy beans and also in crude

fore, it could have superior feed
ing value to soy beans or velvet
beans. I intact, we think 1t runs
right along with these crops. All of
these crops may be planted as soon
neas the soil warns up sufnclently TO
insure rapid termination.
Any Of these crops may be planted
in corn, Or they may be soWn by
themselves in three to three and
half-foot rows. 1t will take from
four to six pounds of seed to plant
an acre of soy beans or mung beans.
More soy beans will be required in
the case of those varieties in which
the seed is very large. In the case
of velvet beans, only a. limited
amount of seed per acre Is needed
because this crop may be planted
in hills five to ten feet apart in each
direction. Velvet beans are good soil
improvers, though it is g. valuable
hay and grain crop as WELL We re-
gard soy beans or mung beans as
superior to velvet beans for hay or
grain production. The velvet bean
does well planted in corn; in fact,
it is the most desirable way in which
to utilize it. The cost of the seed will
vary a good deal; but you can secure
pound, depending on the variety
selected and the skill with which the
planting is done. You can probably
secure locally grown seed at lower
cost. think you will find the Laredo
bean one of the best varieties to
plant. It has proven to be the best
hay-producer Of any Of the legumes
we have tested up to date. It makes
a large quantity of grain as we'll.
It is quite resistent to the nematode
worm. 1t should grow very success
fully on the re Glands in your Sec
ton Of the state.
Using Potash on Our Red Lands
A. s. A., Danburg, Ga, writes:
The land in our section is the
Cecil coarse sandy loam, and l
understand that our soil is sup
posed to contain plenty OF pot
ash for growing crops. What
fertilizer would you advise me
to use under cotton and corn?
My SON has demonstration
patch (which he wishes to
grow q large yield of cotton.
What variety would you advise
him to use?
We are inclined to think that you
will find the use of some potash on
the soil described in your letter both
desirable and profitable. 1t is true
that many of the soils in north
Georgia contain a high amount OF
potash This has caused some con-
fusion to arise in the public mind.
There is all the difference in the
world between a total potash con-
tent of a soil and the amount which
is available. Only that part which
is readily dissolved in the water of
the soil and which can therefore be
taken UP by the roots of plants is
to be regarded as available. Untor'
tunately, a great deal Of the potash
containe din our north Georgia clay
soils Is held in combination with
iron and alumina. 1t therefore be-
comes very slowly available, and 1t
is for this reason that we have
found the use of moderate amounts
of potash to be beneficial to the
crops raised here on the college
farm at Athens. The lands upon
which we operate are similar to
those found in Wilkes county.
It is our intention this year to
use 1898 under cotton and corn.
All our experiments indicate that
the application of liberal amount
of phosphoric acid is desirable. In
your location, it will probably pay
YOU to use per cent of nitrogen.
We vary our potash formulas from
3 to 4 per cent, and there will be
NO objection whatever to your using
al 1914. In fact, we are inclined to
Vfhink it is the most beneficial formu-
la to use under both corn and cot
ton.
Under the conditions portrayed.
we would suggest that your son use
either we'll selected strain of Col
lsse No. l or Cleveland Big Boil
We regard these as two OF the best
varieties for cultivation under the
conditions prevailing in north Geor
gia at this time. We need strains
that will mature relatively early on
account of the boil weevil. We neeo
to grow only standard varieties OF
cotton; that is, those strains which
