Drought Damaged Corn
The dry weather in 2006 has many effects on the grain produced. Most notably
is probably yield. With more and more grain being stored on the farm, there
are some other factors that warrant consideration.
Low test weight corn can result in storage problems.
Initial moisture
readings on low test weight corn can be unreliable for several reasons.
 |
First, low test weight corn
is soft so only the surface dries. The internal portion remains wet, but
evens out in storage to raise the overall moisture content. For example,
low test weight corn put in storage at harvest at 14-15 percent moisture
could be 16-17 percent by spring. |
 |
Low test weight corn is more
likely to take on moisture in storage. |
 |
Low test weight corn is twice as
likely to spoil as heavier corn at the same moisture. Softer corn breaks
more easily when handled. |
Weekly bin checks will help identify problems before they become
unmanageable. Sample grain bins from the top and bottom for moisture content
and temperature to determine general condition of the grain. Record the
results to monitor changes.
Management Strategies:
 |
Keep corn with a test weight
of 54 lb/bu or higher separate. |
 |
Use test weight to determine
how long you should keep corn. If grain test weight is less than 53 lb/bu,
sell it first and if possible before summer. It will go out of condition
quicker than heavier corn. |
 |
If moisture content is 16
percent or higher, reduce the moisture level either with aeration or
grain dryer. |
If other problems arise, move
the corn to market as soon as possible. Repeated handling to control
hotspots will probably result in further damage to the grain and accelerate
deterioration.
Aflatoxin is a term we hear often, especially in years with drought stressed
corn. Aflatoxin is a poison to humans and animals and is produced by a mold
which grows on corn kernels. This is more prevalent on drought-stressed corn
damaged by earworms. Light test weight and damaged kernels also are more
susceptible to infection by this organism. Producers that plant Bt varieties
may have fewer problems with aflatoxin because these varieties have less
damage due to earworms. Because of its toxicity, grain buyers will reject
truck loads of corn containing 20 parts per billion of aflatoxin.
According to Allen Wrather, Professor, University of Missouri-Delta Center,
to reduce the risk of aflatoxin, producers should dry wet, freshly harvested
corn to 15 percent moisture within 24 hours. The mold grows best when 18
percent moisture corn is stored at 86 degrees F. While aflatoxin may be
produced by this mold on kernels in the field, major mold growth can occur
on wet, warm corn kernels stored on a truck or in a grain tank for several
days. Never store wet corn (greater than 15 percent moisture) for more than
one day without aeration or drying.

BVD Virus in Cattle
Bovine viral diarrhea virus (BVD) is
known to cause immune suppression, respiratory disease, infertility and
fetal infection. The economic losses from infection will vary greatly
between herds.
Infection of the fetus during pregnancy can lead to early embryonic death,
abortion, birth defects, stunting, or the birth of persistently infected
(PI) calves. Persistently infected cattle can result when susceptible
pregnant cows are exposed to BVD virus during mid-pregnancy and the virus
passes from the dam to the fetus. Many times infected fetuses are aborted,
but if a PI fetus survives to term, it will always have a tremendous amount
of the virus in its body and cannot mount an immune response to clear the
virus. A PI animal will secrete BVD virus throughout its life; in contrast
to animals that become infected after birth that secrete the virus (are
contagious) for a few days to two weeks.
At least 20 to 50% of PI calves die prior to weaning age, but a few look
normal and have normal growth until weaning age or beyond, which is why it
is important to test all purchased and raised replacement heifers and bulls.
PI calves (suckling animals or replacements) that are alive during the
breeding season are the greatest concern to ranchers because they are in
contact with the breeding herd during early and mid-gestation.
Calves persistently infected with BVD can be identified by a number of
laboratory tests. A relatively new test that is very accurate for any age of
animal (even newborns) is performed on a small skin sample taken from the
ear with a pair of ear notching pliers. This test differentiates between PI
animals and animals that have been exposed to the virus, but have or will
generate an immune response.
Vaccination programs can provide fairly good protection against BVD induced
disease when the exposure is from non PI animals. Vaccination programs are
an important component in BVD control, but will only offer a high level of
protection if herd contact with PI animals is eliminated.
Recommended Control Strategies:
For a farm that does not have any evidence of BVD problems – high pregnancy
percentage, low calf death loss, etc.
 |
Prior to the start of the
breeding season, use skin ear notch test on all new replacements: bulls
and heifers (home raised or purchased) |
 |
MLV vaccination program of
replacement heifers |
 |
MLV or killed vaccination
program for adult cows (MLV if timing allows administration while open) |
For a farm that has evidence of
BVD problems – many open cows, abortions, stillbirths, or high calf death
loss, etc.
 |
Prior to start of breeding
season (most or all calves should be born), ear notch test all calves
and any cow that does not have a calf at this time (aborted, never got
pregnant, lost a calf for any reason) |
 |
Ear notch test all new
replacements (bulls and heifers – purchased or raised) |
 |
If any calf comes back as a
PI animal – euthanize or slaughter it (don’t sell it) and test it’s
mother (there is a slight chance that dam is also a PI) |
 |
Cows with PI calves that are
not PIs themselves do not need to be culled because they now have
excellent immunity |
 |
Modified live virus (MLV)
vaccination program of replacement heifers |
 |
MLV or killed vaccination
program for adult cows |

Conservation Easement – What and Why
A conservation easement is a legal transfer of right to use all or part of a
property for a certain purpose. Since the transfer is of some but not all of
the property rights, it is known as a transfer of "limited rights”.
Conservation easement is really a misnomer. The owner of land subject to a
conservation easement is not required to implement conservation measures or
institute practices to reduce pollution. Usually the owner gives up the
right to develop, improve or modify his or her property and the buildings on
it. The owner, however, keeps the right to sell, transfer ownership or give
away the property. He or she may continue to live on the property, develop a
portion of it excluded from the easement, and keep any subsurface mineral
rights.
In a conservation easement, the limited rights are transferred from a
private landowner to a nonprofit conservation organization or government
agency. The organization or agency is given the right to enforce the
easement. The public receives no right to enter the property.
Many
conservation organizations and local governments are interested in
conservation easements as a way to acquire "green space" in an area that is
being developed quickly or which has special values to preserve. Landowners
may have several reasons to favor a conservation easement. They may wish to
ensure that property is left in an undeveloped state even after their death.
Landowners also use qualified conservation easements for financial and
estate planning purposes. The easements allow landowners to reduce fair
market value of their property which can impact income, gift, estate, and
property taxes.

Taxation Tidbits: New Rules Affecting
Charitable Donations
Our income tax code got a few new
wrinkles on August 17th with the signing into law the “Pension Protection
Act of 2006”. This Act, in addition to pension tax law changes, contains
some new provisions that will have ramifications for charitable donations.
First, the Act eliminates a tax deduction for used clothing and household
items donated to charities – unless the items are in “good” condition.
Unfortunately, or perhaps fortunately, the Act fails to define what is to be
considered good condition. This change is effective for donations after
August 17.
The Act is more definitive regarding the substantiation of cash
contributions. Effective after August 17th cash donations of any amount must
be substantiated by a cancelled check, bank record or written documentation
from the charity verifying the amount and date of the contribution.
On a more positive note, the Act allows taxpayers to make tax-free
distributions from their IRAs for charitable purposes. This provision is
available through 2007 and has a $100,000 maximum annual limit.
Finally, another provision included in the Act which will be of interest to
some landowners is the increase in annual charitable deduction limits for
qualified conservation easements. For years 2006 and 2007 the deduction as a
percentage of adjusted gross income is increased from 30 percent to 50
percent. For qualified farmers and ranchers the deduction is increased to
100 percent of adjusted gross income provided the property remains available
for agricultural production.

EDEN—Not the Garden
We would expect that this time of year the
tornado season would be over. However recently we had significant tornado
damage in Missouri. This is a reminder that we could have stormy weather any
time of the year. University of Missouri Extension has information on how to
cope with many types of emergencies. Hopefully we are moving away from
tornado season, but we can now move into winter weather problems including
snow and ice. Now is a good time to prepare yourself, your home and your car
for this season. Missouri resources can be obtained at your local University
of Missouri Extension Center or accessed at the following web site:
http://outreach.missouri.edu/cemp/preparedness.html
We would especially encourage you to read resources on preparing for a
disaster, preparing your vehicle for winter driving and safety after ice
storms. We all need to prepare ourselves and our families for the situations
we will encounter before they happen.
In addition to having many resources in our local extension offices on
emergency preparedness and coping with emergencies, we have a national web
site called EDEN (Extension Disaster Education Network). Their web site is:
http://eden.lsu.edu/. This is a good place to look for information on disasters of many kinds as
well as biosecurity issues.
Biosecurity is something new to us in agriculture.
The EDEN site has many
suggestions. A sampling follows:
 |
Farm Security
Agrosecurity is an ongoing process and is implemented through a set of
actions and technologies designed to protect livestock, crops, facilities,
data, and other assets. The physical security of the premises is the first
step toward ensuring the safety of our food supply. This includes fences,
locks, electronic surveillance systems, alarms, and other hardware and
software devices.
|
 |
Anhydrous Ammonia and Farm
Security: |
In addition to protecting our
food supply, sound agrosecurity procedures are necessary to prevent the
theft of chemicals, such as anhydrous ammonia used to produce meth
(methamphetamine). These thefts continue to be a concern in rural areas. In
order to ensure that anhydrous ammonia or other chemicals are not stolen,
please follow these simple security practices.
 |
Try to minimize the amount
of time that the chemical tanks are on your property.
|
 |
Purchase or rent a locking
device for your nurse tank. |
 |
Consider the use of motion
detectors or other devices around your nurse tank.
|
 |
Visually inspect the tanks
each morning. |
 |
Place a wire tie or seal
around the valves to aid in quick inspection.
|
 |
Know your inventory.
|
 |
If you suspect theft of
anhydrous ammonia, or any chemical, contact local law enforcement
immediately. |
 |
Agrosecurity Plan
|
Every farm and agricultural operation should have an agrosecurity plan which
should include the following:
 |
Do not allow animals of
unknown health status to enter the herd. |
 |
Work with a veterinarian to
determine an adequate vaccination program. |
 |
Limit herd or crop contact
with visitors. |
 |
Properly clean and disinfect
animal areas. |
 |
Always report any suspicious
activity to local law enforcement. |
 |
Any suspicious animal
illness should be reported to state or federal veterinary officials
immediately. |
 |
Personnel Concerns (Some
Examples): |
 |
Have all potential employees
fill out an application. |
 |
Screen potential hires
including references and background checks (police record, employer
recommendations). |
 |
Institute a probation period
for new hires. |
 |
Educate your employees and
customers on the importance of being alert for signs of possible
tampering with crops, livestock, supplies, equipment, and facilities.
|
 |
Develop a system to identify
employees and visitors; schedule arrivals and departures.
|
 |
Train all employees on
agrosecurity. Include periodic refresher training.
