I had a soil test done on my yard this spring and received some recommendations from the company. My soil is pretty low fertility so I already took care of the last two numbers and I'm getting ready to apply just nitrogen in mid April. The recommendation was for 33-0-0 at 3 lbs per 1,000 sq feet. This sounds a little aggressive for centipede but maybe the soil is so bad it might need it. Anyone applied a nitrogen only fertilizer before and did you burn the lawn? That's what I'm really afraid of by doing this much nitrogen.

3 lbs will not hurt it. I put twice that on Bermuda grass.

I would say that is a little aggressive. That is nearly the yearly recommended rate for centipede in one dose. I like to split that into two applications. One in spring, and one in late summer.

Bermuda will take nitrogen like none other. I use straight urea several times a year on my ball fields. More than 1lb/1000 of N on centipede onsets centipede decline.

Can 33-0-0 even be bought at farm stores?

33 0 0 is urea . 46 0 0 is ammonium nitrate . I use both on my hay fields depending on which is available.

You can get 46-0-0 Urea.

You need to remember the recommendation is for 3 lbs of 33-0-0 not 3 lbs of actual nitrogen.

33-0-0 is ammonium nitrate and 46-0-0 is urea.

33-0-0 is ammonium sulphate
34-0-0 is ammonium nitrate

Doesnt matter which you use.

If you use urea—often 42-0-0–you can use proportionally less.

Lot of confusion up in here. The first number is a percentage of nitrogen no matter what form.

You can also still get ammonium nitrate but it will have sulphur added to keep you from blowing something up.

So just to be clear, if I had a 2,500 sq ft area and went off the recommendation of 3 lbs per 1,000 sq feet of 33-0-0, would I fill up broadcast spreader with 7.5 total pounds of this and apply over the area? This is my first time measuring fertilizer and not just using a setting from a Scotts bag.

I work in a urea plant making pure liquid urea. How much would you say I would have to dilute in a 2 gallon sprayer to hit some dead spots in my yard?

If it is 46-0-0 just spray it directly on the soil since you don’t have to worry about burning the foliage. Don’t soak the ground with it but just lightly spray it back and forth with the wand. We run a straight liquid N-sol that is 32-0-0 at 30 gal/acre over the top of growing wheat. It burns the leaf a little but it recovers very quickly.

I can’t find anywhere that sells 33-0-0. I’m either going to have to go with 21-0-0 or 32-0-10.

I’m up in Monroe and called around with no luck. It shouldn’t be a big difference using 21-0-0 if u apply correctly?
