| How come this Corn is NOT LEMON YELLOW?
Soil test sez: Top 2 feet of soil has only 10 # of N / Acre (Nitrate-Nitrogen per Cd Reduction, from a Servi-Tech Lab),
(The $800 do-it-yourself N tester shows 15 # of N / Acre - NO3-N - but I'm new with it, so results are sketchy....)
Corn is at V-8.
....so it has only taken in 20% of the N that it needs.... (Or was it 20% at V-6?)
Anyway,
Should I panic & Quick Apply 200 more #'s of N ???
That field has been corn-on-corn for 10+ years...
It had 180# actual N, broadcasted (dry) in Nov., followed by rain 10 days later... and then 40 # actual N (dry), in the strip, pre-plant.
Plan was to Dribble 32% beside the plant with drops, at about V-8.... then to make a round with sprinkler.
Goal is 230 bu... (Actually, goal WAS 250+, until hail shredded 1/2 the leaves...)
Anyway,
The Soil Test was supposed to show how much more N to put out...
But test results do NOT agree with the crop condition....
WHY IS THIS CORN DEEP DARK GREEN?
OK - the bottom leaves are toast.... The little 3 & 6-inchers.....
...some lab's Soil Tests show an additional kind of N...
Does anyone know which labs do that test, and what value other kinds of N has to corn?
Is this corn gettin N from somethin besides Nitrate?
