does this compare with our 16 per cent
acid phosphate for corn, peach trees and
grain?
Undoubtedly there are MANY sam
Piles of Tennessee ground phosphate
rock which will show 80 per cent of
total phosporic acid. Probably little
or none of this is available, how
ever, and it will take some time for
it to become OF any service to crops
grown on land to which it is ap-
piled AT least this represents our
experience and observation in dealing
and experimenting with material of
this character. On lands which are
well supplied with organic matter or
which are naturally rich in this ,ele-
ment, such as swampy, loW-lying
soils, finely ground rock phosphate
can often be applied with advantage.
In any event, we think you should ex-'
pect to use not less than 1000 to
1000 pounds per acre. In the pres
ence Of the conditions you have de-
scribed this material is likely to
remain in the soil in a rather mac
tive condition for a long period of
time. If applied to land where large
quantities Of yard manure are avail
able it will give good results. 1t
may also be incorporated with yard
manures as they are made and put
out in compost heaps with consider
able advantage. If you desire to Sc
cure quick and Immediate results,
however, and to supply the growing
crops with a readily available form
of phosphoric acid we are inclined
to think you will secure the best
returns from an application of 1.-THE

SEEDING LEsPEDEEA CLOVER In
THE SOUTH re
A. r. B., Dublin, Ga. writes: How
much LespedeZa seed should l SOW per
acre, and where can | get the seed!
Will it make good pasture for grazing:
You should have no difficulty in
securing lespedeza seed through any
reliable firm handling general farm
seeds in the state of Georgia. [ am
sure there are individuals in your
town who could aid you in securing
what you want.
Lespedeza, as you know, is a sum
mer-growing clover. It's common
name is Japan clover. 1t was i'm
ported into this country some years
ago and has now spread over con-
siderable section Of the south. 1t
is a valuable addition to grazing
lands. 1t should not be seeded in
the spring until the ground has
warmed up and all danger of cold
weather or frost is past. 1t should
be sown say at the rate of eight
to ten pounds per acre and broad
casted as uniformly as possible over.
the land. If it can be scattered more
uniformly with seeder use one to
distribute it. A light narrowing of
the land very often proves beneficial.
This clover is rather slow to es-
tablish itself and hence you must
not expect it to make a big showing
the first year. Once it developes,
however, it will hold it's place in
the land and will gradually spread.
1t is valuable for grazing during
the warm months, but it is cut down
by the first frost in autumn. 1t
has the ability, however, to reseed
itself, which is great advantage.
One hoping to develop permanent
pasture lands in Georgia will find
this clover very valuable.
Early Maturing Varieties of Cotton
H. L. S., Gatesyille, Ga, writes: .
Which is the best variety Of cotton to
plant under boil weevil conditions We
I have been planting Half and Half, but
think of using Cleveland's Big Boil next ,
year. ANY suggestions you can give me
will be appreciated.
In your section Of Georgia we pre-
sumo that some strain of Cleveland
Big Boil College No. l, Hooper's Big
Boil or Texas Burr would be found
the most satisfactory variety of cot
ton to use. Half-and-Half cotton,
as you doubtless know, is subject to
attack by the disease known as an
thracnose. In our tests here it does
not appear to have matured as early
as some of the other strains mem
toned. In a survey made of Geor-
gia we found some strains of CleVe-
land Big Boil we're more extensively
grown than any other standard Varl-
ETY. of cotton. Our experience here
at the college has indicated that 1t
is one of the earliest and most de-
sirable types to plant in north Geor-
gia under boil weevil infestation. It
sets on a considerable part of its
normal yield, of fruit early in the
season and continues to grow until
frost. This is a very desirable thing
for it to do, as it affords the weeyil
fresh squares to feed throughout the
season and thus allows the early set
on bolls to develop and mature with
out injury.
There are several strains of this
variety of cotton, among which we
