ORCHARD CULTIVATION.
The Practice of Manure Mulching
Compared with Other Methods
of Treatment.


E. f. Spradiing. Graham county.

mile from home and wishes to know II
he can mulch them with stable
manure SO as to avoid cultivation. He
intended to do this until he saw an
article by the writer on cherry grow
ing. asserting that mulching caused
the roots to grow too close to the top
of the ground. He wants to know if
apple. pear and apricot trees will Oe
affected the same way.
The position that roots take in the
soil whether near the surface or
deeper down depends to q consider
able extent on the region. says the
Prairie Farmer. Under shallow cul-
tivation the oxygen of the air pene-
trates the soil. OXygenation sets free
latent plant food. at just the pcint

happens when We mulch with straw
to the depth of II to 20 inches. Ii

pacted lesser depth would produce
the same result.
Under such conditions the writer
has seen tree roots as large as your
finger on the surface OF the ground.
AS long as the heavy mulch was kept
up no harm resulted from this surface
roofing. When howeve' the strawy
litter rots away exposing this root
system, then the tree suffers. Where
the soil can be cultivated once a week

veiopment of latent plant food can go
forward while conserving moisture.
A mulch Of two or three inches of
stable litter loose upon the surface
would not be likely to bring the root
system to the surface in one season.
An occasional working of the .isk
or cultivator running through his
mulch would combine the best tea.
lures of both methods.
AS the trees get larger with a sp. cad

more it becomes more difficult to sui.

We have secured excellent results By
mulching the row of fruit trees to the
width of six to eight feet from end

ing portion of the orchard open with
plow, disk, harrow or cultivator Wa
have had most excellent results in or.
chards with this method. The mulch.
ing of stable litter conserved soma
degree of moisture, increased the fer
tility of the soil and kept the weeds
down on the ground that could not
be easily reached with plow or c'tlti.
vator. Our most successful cherry or
chard was handled in this manner.
We would very much prefer to use
stable litter for this combined 2ur.
pose Of mulching and culture than to
use straw. To certain extent bright,
fresh straw reflects the sun against
the trunk of the tree and IL inches
of straw is no more effective than two
or three inches of stable litter.
In further answer to your corre
spondent, we suggest that where the
trees are planted half mile from
home and apt to be neglected, would
use the combined method of narrow
mulchinS and cultivation.
