Fertilizer before top soil?

Had about a dozen pine trees removed from my front yard. Going to have topsoil brought in. I had a soil test done was not as bad as I thought it would have been. Carbon x seems like a good idea. My question is should I put some down before the topsoil. And then put some starter down when I seed. This is my first time starting from scratch with a yard

Is your idea to get the roots to dig deep to hit that pocket of nutrients?
I do this in the vegetable garden, I dig a deep hole mix organic fertilizer with some dirt/peat moss then put the plant on top. Never done a control but this seems to help get roots deep into.more consistent water.

This is my experience with vegetables and immediate planting of started plants. I would worry about a synthetic washing away in the time it takes for seed to sprout and get roots down deep enough.
This might sound crazy but wonder if this might be a case for chicken feed as organic matter to get the soil biology working.

Mainly was worried about getting some type of nutrients in there because this are hasn't had any type of grass on it for 20 or 30 years. The pine trees blocked all of the sun and dropped their needles. Not making the nicest area for growing anything.

When you say chicken feed does that give nutrients as it breaks down in the soil. Appreciate all the feedback

For Nitrogen, it would be more effective to broadcast at the time of or a few weeks after seeding. For Phosphorus, you would benefit from mixing it into the soil profile since it does not move well in soil. Mixing will distribute it evenly to whatever depth you till, whereas broadcasting on the surface will leave a higher concentration at the surface that declines as you move down in the soil. Potassium is more mobile, but would also benefit some (but not as much as Phosphorus) from mixing.

Any Nitrogen you add now will be gone by 2 months unless it is some form of long release Nitrogen. If it is stabilized Nitrogen, how much is left at 2 months will depends on the specific type of Nitrogen used. Phosphorus applied now will almost all stay until it is used by plants. Over months, the Potassium will also stay in the soil until used by plants.

How much difference it would make to add now and mix is an open question, though mixing probably helps some for P and K. You can get excellent results from broadcasting Phosphorus and Potassium, so whether the extra work is worth it is a bit unknown.

I agree I watched past tense some Doc videos and he is a salesman and I mean that in the most derogatory way.
That said a basic unmedicated layer chicken feed is a cheap way to add organic matter. It is all ground up seeds. Seeds are inherently high nutrient since they are designed to grow a plant. I wouldn't use it as fertilizer but I can see benefit in $13-50lbs. organic matter. Yeah municipal compost is free but God only knows what is in it seed and chemical wise.
