First time growing corn, curious of what I should put down for fertilizer.
This will be my first year growing corn. I am in the far north part of north dakota where a fantastic crop is 150 bushels. I am wondering what a good place to start for fertilizer would be. Its on last years soybean ground so i am counting on a couple pounds of nitrogen from them, but as far as 11-52 use and urea use or even other dry fertilizer types i am at a loss. Any help would be greatly appreciated
You need find a good agronomy guy. Not a coop guy but a private guy that doesn’t sell nutrients. Soil sample then get recommendations. In my world that would be 180 pounds of nitrogen. 135 pounds of phosphorus. 30 pounds sulfur. But all ares are different. Each farm is different depending on soil test.
Kind of a loaded question really , but the answer above is good advice. Anhydrous will generally be the cheapest N option, but depending on availability, tillage practices, preferred timing during the growing season, and machinery availability may not be the best or possible. Some guys around here have their N custom applied in 28% or 32% liguid with their pre chemical right before planting. Some do it all then, others do part then, then side dress the rest later. Some will broadcast a certain amount, apply some with the planter, and then side dress. Most of the Phosphorus and Potassium around here are custom applied with a floater. A few guys are running strip till and knifing it under ground with a prescription exactly where the row is, but while it is probably the best way, the equipment to do that is out of reach for a lot of farms. Corn removes .38 lbs./bu. of phosphorus, and .3 lbs. of Potassium/bushel yield. Make sure your hybrid selection matches your soil type and growing season. If we carry 5$ corn through the end of February, the crop insurance revenue guarantee is going to allow for a pretty lenient learning curve.
The previous posts are good advice. Not sure where exactly you are, but Centrol crop consulting service is probably close by you and has all the answers you need without trying to sell products. If you are in the valley i'm guessing your organic matter is pretty high so your nitrogen application rates might be pretty low. But, don't be afraid to get good Local agronomy advice. Good luck to you. Please let us all know how it turns out.
Not sure if it would help being I'm in Arkansas. First year planting corn 2019. Shallow soil here no black dirt. Topsoil is usually couple inches then fragpan. Used to raise rice good for that. 2 ton of chicken litter pull hips aka ridge till. 240lbs urea with stabilizer 4 weeks later. Avg 165 not bad here for what I put in it. Didn't want to spend more than what insurance yield was 133 bu guaranteed. Planted a conventional to save on seed at 27500. Set myself up for no chances of financial failure on first crop of corn.
My response is too late for this growing season, but you really need a good set of soil samples to know what is in your ground and what the CEC is so you know how much fertility it can hold at one time.
