Of Precipitation as That Of
Arid West.
In Campbell's dry farming or scien-
tiflc soil culture we have the opening
of the heretofore-called American
Desert or the arid region of the west.
Land which was formerly considered
unfit for agricultural purposes be-
cause Of the lack Of water is now
yielding fair crops to the man who is
just learning the why's" and where
fores" Of the proper tilage Of the soil.
writes Guy s. Ellis In the Breeders
Gazette. The fact that this land
yields crops Of fair average has
brought many to study the theory Of
dry farming. The subject might also
have . direct bearing on the tillage
Of land in the humid region. In the
humid region we usually find time
when during the summer months we
wish to SOW forage crops or turnips
and there Is not moisture enough to
start the seeds or to supply the needs
Of growing crops. Here is where dry
farming methods can be used to ad-
vantage in a region with double the
amount Of precipitation as that Of
parts Of the arid west.
The first requisite Is firm sub
soil. In firming the sub-soil. We
break up the large Jumps and compact
the whole SO that the particles Of soil
lie closer together, forming a perfect
connection between the unbroken sub
soil and the loose soil Of the furrow.
Capillary connection is established.
that is, the very minute pasageways
are established through which the
soil moisture can rise from the sub
soil to the soil above. BY using a
harrow or disc dust mulch can be
made which will hinder the further
upward passage Of water and hold 1t
within reach Of the growing plants
or sprouting seeds.
A firm sub-soil which is in good
physical condition Is favorable to
holding large amounts Of moisture, and
to the most rapid movements Of mois'
ture by capillary attraction. 1t is also
favorable to the development OF
the greatest amount Of available
fertility and the most prolific
growth and development Of lateral
roots. We should therefore bear in
mind that the soil is natures labera'
tory, where the proportions Of all
and water may be combined In just
the proper quantities. II the soils are
too loose. then there is too much all
for the water the soil can hold. and
only under very ideal climatic con
ditions can a fair crop be grown
With a firm seed-bed In which the
soil is in good tillage and the mois
ture near the surface, we have goot
medium in which to plant seed. Il
the soil has been properly tended
these conditions can be carried thui
throughout the season.
The process Of farming the sub-soi
furnishes Ave aids in carrying thu
growing crops over long dry periods
We have more water in the soil. BY
destroying the many large non-capil
larry pores in the surface soil We
bring Its grains closer together ant
the water Is aided In It's upward pas
sage.
We gain a stronger capillary move
ment OF moisture. Prof. F. II. Kine
of Wisconsin says. I'm rolling the sol
It's water.lifting power Is increased te
such an extent that often within
twenty.four hours after rolling. the up
per / minute to minutes beneath
the firm ground contains more mois
ture, while the lower minutes be
come dryer than soil adjacent which
is left untreated."
We have more rapid development
Of bacteria and nitrates. There Is
no time OF the year. according tt
Campbell. when water held In the
soil near the surface In sufficient
quantities will bring about as many
valuable chemical changes as In July
and August. A large amount Of bac
terra and nitrates are developed then
This comes during the months wher
Iowa generally has her drouth. II she
has any. and to get these valuable
chemical changes We must study ant
use proper tillage methods which vii
nut this moisture near the surface.
There is a more prolific growth o.
roots. Roots or rootlers will not pene
trate air spaces In the soil 30 II w

must first see that the ground is pack
ed so az to break up the Jumps ant
bring the surface soil particles closer
together. Again the development O
bacteria and nitrates aid In making
vigorous root systems. The moisture
