Fertilizing opinions.

Well, I decided to do all corn this year, no beans, just to keep it simple. So, I will not have enough manure for all the ground and I was wondering what some of you thnk about pre plant fertilizing. Last year I spread recommended rate prior to final tillage and planting and should have been done for the season. We got quite a bit of rain and apparently I lost alot of nutrients so ended up sidedressing later, july 2nd. I am on light sandy loam soils. Am I better off just tilling, planting with the liquid started and putting the main fertilizer at a later date. Or is it best to get it in prior to planting? Heading out to work up that feild with Volunteer rye now and am hoping to have all manure spread and feilds ready to plant by next weekend, hopefully before the predicted rain or right after. I just dont want to waste fertilizer.

I've been putting down anhydrous preplant,then banding everything else dry with the planter.

Just don't buy it from the same Elevator that Redtom went to........

Dave I spread P and K in dry form in the fall or early spring.

I put on 10 gallons of 28% nitrogen with the planter. I started doing this cause I sidedress on my N when the corn is knee high. Before using N with the planter my corn was suffering from lack on N before I got there with the sidedress N.

By sidedressing knee high corn I can get the same yields by using lower amounts of N than I would if putting down the N earlier.

If you have time to sidedress it pays in lighter soils where N tends to leach out sooner. I have lighter soils also.

IaGray;

I didn't know Iowa had any "light" soil. I've hunted around the Amana Colonies and those wet fields add 10# to each boot, not to mention making it a bear to clean the dog's feet.

Larry I am about 5 miles east of the Amana's.

I am in the Iowa river valley and all the ridges around here are sandy soil.

You go 3 miles any direction and there is no more sand.

Notice the soil in this old photo on top of a hill.

You get down off the ridges and I have black dirt.

If you do not want to waste fertlizer have a soil sample tested to see what you need and where you best put you money.

Soil Test have been done, as well las manure sample tests. What I am mostly concerned about is applying what I need during periods that it will be utilized by the plant the most and lose as little as possible to leaching.

Banded P & K you can get by with 1/3 less. The band becomes super-saturated & releases more to the plant this year. Otherwise, broadcasting those you end up mostly fertilizing for future years, maybe sometimes only 20% is available this year.

You can't put all the P & K on as liquid in the seed trench, so you would be looking at banding 2x2 - 2 inches to this side, 2 inches below the seed.

Or, strip till, where the strip gets the load of P & K and even most of the N.
