| Am I dumb for spreading 40 lbs of urea on for soybeans ? I have good yields . Can I get those same yields with less fertilizer ? What does everyone think am I dumb for doing that ? |

| We spread DAP & potash before corn & beans every year. We feel we get better yields th a n when were were dpreading everything in front of just the corn.
edit: after reading some of the other posts I will this is a high yielf enviroment. Moxt of my APHs are in the 60bpa area so am trying to get a bump from there.

| I have tried it a couple times and have never saw an increase in soys. I have read that high yielding soys might require additional N but don't know anything about that. |

East central Indiana | Coop put 100 lbs of urea on about 5 acre out of 26 by mistake. No difference in yield, little more logding. |

| Urea has no real noted effect on yield UNLESS you get beyond 60 bushel an acre, there is data that indicates 60+ bushel soybeans can have an economic return with fertilizers. However, in my own experience, 100 lbs of 11-52-0 or 22lbs of N and 104 lbs of phosphate will give you a 3-5 bushel yield gain consistently with soybeans provided they are 50+ bushel which means timely rain for me. It's the best bang for your buck here but I don't do it on every field each year. Economics plays a big role in that. |

| Did you mean 200 lbs of MAP or?? |

Illinois | I spread 125 pounds of DAP and 125 pounds of potash ahead of my soybeans for the 2016 crop. This year was the highest yeilds I have ever had. I spread heavier ahead of corn.
I assume you are doing this for yeild. Higher yeilds mean higher removal rates. If you want to apply some N do it as DAP or MAP. If you don't have higher yeilds then you still have the excess fertilizer for the next crop and can cut back rates accordingly.
Edit: as another poster said to see a response to the nitrogen fertilizer you would have to be in a higher yeild environment where that plant can utilize the N. What yeilds do you see normally? What is your crop rotation

Pilot Grove, Missouri | 100# of MAP is only 11# of N and 52# of P. Patrick |

Carbondale, KS | To start w/, why do you give a rat's @$$ about what others think? Maybe your question was just misworded. I will tell you i've seen ZERO yield increases from nitrogen apps in the spring....this is upto 180#. I have never tried putting it down at or during any of the reproductive stages....there may be some merrit to that IDK. There were a few instances i saw yield losses and just from my observations (always unscientific), there was little to no nodulation so i concluded they didn't have the nitrogen bank to draw from when it came to grain fill.
Bottom line was it hurt when i did that, so i stopped doing it. |

| few years ago I was fall applying fertilizer for next years corn and was right next to a field which was going to be beans the next year. I made a few passes into that field with the same rate as I was using for my corn ( this was n, p, and k). The next year I planted the beans and they were taller and greener all year long, but when I came with the combine it was only a bushel or 2 better, I believe this field averaged 45-50 that year.
One agronomist was trying to talk me into strip-tilling my bean ground with p and K, he claimed it was really going to make a difference. I did 3 replicated ways. 1 pass was strip-tilled, next pass I left strip-till up in the air but blew fert on top of ground, next pass no fert, I then repeated 3 times. When the combine came it again was statistically even across the strip-till, no-till with fert, and no-till without fert. I believe this field averaged just over 50 that year.
That said I still fertilize my bean ground so as not to be mining nutrients but I believe a good stand, no weeds, and timely rains in the fall is what makes a good bean crop. |
