I didn't catch where you are....
I am in virginia.
the extension service in our state gets a lot of lip service but it is no longer an essential part of the university and is constantly under funded and they have bought out all of the older experienced agents.....
be that as it may....
here producers have to have a nutrient management plan to participate in any government programs.
I am a nutrient management planner with over twenty years experience.
we would never advise anyone to put out 150 lbs of nitrogen on small grain at one time.
we plan normally three split applications....hopefully when the crop is green and growing so that it uses the nitrogen rater than volatizing off.
Putting the nitrogen out in smaller applications like you are talking about is a better way of applying it from what i have read also. I am located in NorthWest Arkansas by the way.
As bad as i would like to apply nitrogen to that crop of wheat i have coming up right now. I am holding off until i am more knowledgeable about how much and when to apply it.
I went ahead and took soil samples, dropped them off at the extension office so they could send them to the university of Arkansas to be tested. Waiting on the results to get back. But i have my reservations as to just how much i can trust their results after listening to what these extension agents have to say.
I am not enrolled in any type of NRCS program with this wheat field. So the exspense is all on me.
I do wish i knew of someone with your knowledge and experience to ask for advice in my area though.
I am going to learn how to do soil analysis myself. It can't be that complicated i don't think. At least i will be gambling that the money i am spending on fertilizer is being spent because i feel it needs to. Rather than because someone who i don't know if they know what they are talking about or not thinks i need to be putting fertilizer out in the manner and amounts they are recommending. They don't have nothing to lose or gain.
I am the one who loses or gains from it.
