DHS: Chemical Regulations

Specifically anyone who possesses (November 20, 2007 or later) listed materials above specified quantities will be required to register with the Department of Homeland Security and complete the Top-Screen assessment before January 21, 2008.  

If a farmer does not currently have these materials but takes delivery at a later date then they have 60 days from the day of delivery to become registered.  

Also if someone is registered and then increase the quantity of material they possess (above the amount you told DHS in the original Top-Screen) then they have 60 days to update this information.  


DHS: Chemical Regulations

  • Ammonium Nitrate Fertilizer – 2000 lbs in a shipping package (bags, truck, fertilizer buggies – basically anything except bulk storage)

  • Anhydrous Ammonia – 10,000 lbs total (add all quantities in nurse tanks and bulk tanks to get possess quantity)

  • Potassium Nitrate – 400 lbs in a shipping package

  • Sodium Nitrate – 400 lbs in a shipping package

  • Some common fumigants (check list for specifics)

  • Propane – 60,000 lbs (not counting tanks 10,000 pounds or less)

Anyone who meets any one of the above criteria (or any of the other listed chemicals) should log onto the DHS web page at http://www.dhs.gov/xprevprot/programs/gc_1169501486197.shtm and complete the Chemical Security Assessment Tool.  Once this is completed DHS will determine if your facility is considered high risk and tell you what additional steps need to be taken.  


For More Information…

  • Your County Extension Agent

  • AGR-185: Nitrogen Transformation Inhibitors and Controlled Release Urea


Option 2

  • Have your nitrogen fertilizer custom-applied. Let your ag supply dealer shoulder the headache.


Biotechnology

  • Useful tools when needed

    • weed control

    • Pest management

Rural Myth #1

“Biotechnology automatically equals yield”

Rural Myth #2

“I’m saving money by waiting to spray.”


Soybean vs. Corn

3.0

90 bu/acre corn: 30 bu/acre soybean

120 bu/acre corn: 40 bu/acre soybean

150 bu/acre corn : 50 bu/acre soybean

210 bu/acre corn: 70 bu/acre soybean


Corn Hybrids for 2008

Chad Lee


Corn Hybrid Trials

  • About 140 hybrids

  • 7 locations

  • Compare hybrid relative yield performance

  • Reduce as many other variables as possible.

  • Identify hybrids for your conditions.


LSD = 7.4 bu/acre

Early Average Yield = 170.6 bu/acre

13 Hybrids within one 7.4 bu/acre

2007 Kentucky Corn Hybrid Performance Test

Corn YieldsWoodford County: SDI, 2007

Year: 2007

Location: Woodford County Farm

Hybrid: SS777RR2YGPL

Poncho 1250-treated seed

Planting: May 3, 2007


Agronomics: Planting Date

  • Corn

    • April 1 to May 1: Western KY

    • April 15 to May 15: Central and Eastern KY


Planting date, optimum dates

  • Princeton

  • Lexington

May 1 - 7

April 19 - 25


Corn: Fungicide Question

  • Industry is promoting foliar fungicides

  • Application near VT

  • Guaranteeing yields in some cases


200 bu/acre

Pioneer 31D61 (YGCB)

NLB rating = 4 (where 1 = susc., 9 = highly resist.)

Soybeans


Current Recommendation

  • Full season soybean: 15-inch rows

  • 100,000 plants/acre needed for maximum yield

Next Question

  • Weed control and weed competition?


Next Question

  • Weed control and weed competition?

Scientists question:

Will fewer plants per acre be less competitive with weeds?

Farmer question:

Will I have to spray more Roundup?

Corn on Corn

  • Pulling acres away from other crops to grow more corn, means more corn will follow corn…


United States Crop Acres


Corn on Corn

  • Yield Penalty ~ 10%

  • Diseases

  • Insects (Corn borer; Corn Rootworm)

  • Fertilizer (N, P, K)

  • Logistics


Starch-based Ethanol

  • Improvements in efficiency

    • A better understanding of hybrid effect on EtOH is needed

    • Improved Grain Yield

  • Corn on Corn

    • Yield penalty

    • logistics


Expected Biofuel Yields

** Not sustainable. Need ~4 ton crop residue (root + shoot) annually to maintain current SOM levels. Soybean residue (root + shoot) = 2 ton/year, so need 4 ton + 2 ton from corn to cover soybean year in 2 yr rotation.
