WHY IT MATTERS FOR YOUR FIELDS

Decision Delivered

Your decisions for today and the week ahead:
  • Acreage Report is 1 days out -- position before the number, do not chase it after.
  • Corn is moving through V5-V8 on seasonal normals -- the rapid-growth, nitrogen-demand window. If you split-applied N, this is the sidedress window; confirm your stage with a field check.
  • Corn is approaching the canopy and tasseling weeks are ahead -- now is the time to book your fungicide window if you plan a VT/R1 pass, before the applicator calendar fills. Confirm your stage.
  • Dig an 8-inch root cube on a few plants in continuous-corn fields to confirm your rootworm trait is holding, and rescout soybeans for early defoliators. Verify in-field.
Farm context: Harfmann Farm - 60 acres of hay, owner-operated since 1992 (real intake on file).

What to Watch Today

  • Rain watch: best rain chance today is around 9 PM (30%). Plan field passes around it.
  • Market watch: soy is the mover overnight, down about 7 cents -- watch the cash bid at your elevator today.

Today in Farm Safety

In cold, wet field work, watch for frostbite on fingers, ears, and nose and for the early shivering of hypothermia. Dress in layers you can shed, keep a dry change in the cab, and warm up before judgment and grip start to fade. Source: OSHA cold stress guidance; National Ag Safety Database.

Pony Express 1860

From April 3, 1860 to October 26, 1861, the Pony Express carried mail by horseback between St. Joseph, Missouri and Sacramento, California - 1,966 miles in about 10 days. It was killed by the transcontinental telegraph, but for 18 months it was how farm correspondence crossed the Plains.

Quiz Answer

(b) School lunch (1946) and SNAP. Started October 4, 1935, it bought surplus farm products and donated them to school lunch and relief programs - the original federal food-aid line. Farm price support and child nutrition have been linked ever since. Source: USDA Food and Nutrition Service history.
