There is a humorous sign one
can sometime find posted in an office or business
which contains only the words, "PLAN
AHEAD" on it. The humor derives from the fact that
the last few letters of the sign get progressively
smaller and run down the page, indicating that the
person who prepared the sign certainly did not plan
ahead with regard to fitting the words on the sign.
Most people can identify with this sign. We know that
planning ahead can often actually save time or at least
increase the chances of an activity turning out the
way we want. However, in the hustle and bustle of our
daily lives it is often difficult to find (or take)
time to plan ahead to the extent we should.
Planning ahead can increase the likelihood of success
with forage production just as it can with other human
endeavors. Now that the spring, 1997 planting season
is behind us, it is time to begin planning ahead with
regard to future forage plantings or forage management
techniques. Here are a few examples.
Alfalfa
In Alabama, alfalfa provides one of the best examples
of needing to plan ahead. The main reason is that the
optimum soil pH for alfalfa is 6.8 to 7.0, and most
of our soils tend to be acid. Thus it is important
to apply any needed lime well ahead of planting time
so that it can react with the soil before planting
is done. Even if heavy lime applications are to be
made to raise the soil pH, making the decision to plant
alfalfa only a few weeks before the seed are put in
the soil is risky business if the soil pH is 6.0 or
lower.
The ideal way to prepare a field for planting alfalfa
is to apply lime according to soil test recommendations,
till it into the soil in late spring or early summer,
and fallow the field until planting time in autumn.
If the field is disked a time or two during summer
to kill seedling weeds, this approach will help to
deplete the supply of weed seed in the soil. Summer
fallow also helps create a mellow seedbed which has
good moisture availablity for planting alfalfa in autumn.
Another approach is to apply
lime according to soil test in spring or early summer,
till it in, then plant a summer annual crop such
as pearl millet or a sorghum-sudan hybrid. This technique
allows some summer forage production, creates a "smother crop" effect
for annual weeds and grasses, and again allows the
applied lime to be raising soil pH during summer.
Pasture Renovation
The renovation of cool season grass pastures to include
legumes such as red clover or white clover should likewise
begin well ahead of time. Although soil pH is not as
critical with these clovers as it is with alfalfa,
application of any needed lime during early summer
will be helpful in getting the field ready for the
planting of these clovers in autumn.
Furthermore, if there are perennial broadleaf weeds,
briars, or other undesirable species which need to
be controlled, this should be done prior to establishing
these herbicide-sensitive legumes. However, it is important
to bear in mind that a herbicide should not be used
which will leave a residue which could be harmful to
the legume seedlings (which also falls in the category
of planning ahead).
Hybrid Bermudagrass
In cases in which it is known that a particular field
will be established to hybrid bermudagrass the following
year, it is advisable to scout the area to be planted
to see if there are any species which need to be eliminated.
In particular, control of common bermudagrass by some
combination of tillage, use of a smother crop, and
use of herbicides is needed. To fail to eliminate common
bermudagrass is equivalent to inviting it to compete
with a new hybrid bermudagrass planting.
It is appropriate to mention that the winterhardiness
of bermudagrass is increased by having good levels
of potassium in the soil. Building up soil potassium
prior to winter increases the chances that a potentially
susceptible variety will survive a harsh winter. This
is particularly important for first year stands.
Another way to increase the likelihood of survival
of a new bermudagrass stand or one which is being grown
at its northern limit is to plan to make the last harvest
of the year early enough to allow at least 4 inches
of growth to accumulate prior to cold weather. The
accumulated forage will go a long way toward protecting
the stand during winter. This amount of growth is also
desirable to have present if the field is to be burned
in late winter, which is a recommended practice.
Species And Variety Decisions
Though it may seem strange to be thinking about winter
annuals during the summer, it is actually only about
3 months until many producers in Alabama will once
again be planting winter annuals. Therefore, now is
a good time to be studying variety reports and thinking
about which species combinations and which varieties
of winter annuals would be logical to plant to provide
winter annual grazing during the autumn/winter and
spring of 1997-98.
For winter annuals as well as other types of forages
there is also another good reason for making species
and variety decisions well ahead of time. People who
know what they want to plant can make arrangements
which will assure them of getting the seed. For hard-to-get
varieties, ordering the seed well ahead of time can
mean the difference between planting the very best
or instead planting what is merely in good supply (which
may be only what nobody else wants to plant).
Summary
In order to really do things right, including properly
establishing and managing forage crops, we usually
have to do some advance planning. Although it may be
inconvenient or even distasteful, planning ahead can
often have a big payoff. In any given year it isn't
difficult to find producers who would have been far
better off if they had done a little more advance planning. |
