aerate and pslserize the soil and
conserve the moisture This results
Is conditions favorable for the de
velopment Of bacteria which hasten
the decomposition aud chemical
changes which make plant food
available. These crops tend tc de
plete the fertility rather rapidly and
10 reduce the organic matter. Well
cultivated crops do not remove 50
much soil moisture as the crops in
the other classes.
Small grains and uncultivated an
naal forage crops draw heavily up
on soil fertility and soil moisture.
They reduce the organic matter
rapidly, especially IL the straw is all
removed. MANY soils. after a few
years cropping with grains, become
hner IN texture, more compact and
heavier to handle They dry out
quicker than they used TO. and often
turn over in Jumps and hard clods
when plowed The good tilth of
virgin grass lands is more or less
completely restored TO worn out soils
when they have been put into a
legume or a grass for sufficient
length Of time
As q general rule cultivated crops,
like corn and potatoes, should follow
the grass crops. They have the
ability TO get their food under more
adverse circumstances than some of
the grains like barley and wheat,
and the constant stirring helps
greatly 10 subdue the sod and leave
a supply Of easily available plant
food for the crops that follow.
The grain crops should come in
between the cultivated crops and the
grass crops The cultivated crops
have destroyed many weeds which
might iniare the grains, and they
have prepared plant food and left
the soil in good physical condition.
BY the time several grain crops have
been raised the soil is again low in
available fertility and organic mat
ter, and is rather hard and compact.
The grass crops will! largely correct
these conditions If nurse crops are
used in seeding the land, the grain
crop comes in the proper place to be
used for this purpose.
