Upon sharing a pitcher of beer...

I came up with an idea. Tell me if it's plausible:

When making a dirt tank substrate, say you use Miracle Grow Organic Potting Mix. Sprinkle or spread some EI ferts on top of the dirt, and then cap with gravel or sand. Not a lot of ferts, just like putting cheese on top of your pasta. Your plants would then already have an NPK source and/or CSM+B source right from the get-go. Would this be a good thing to do?

well, why would you need to though, since the dirt already has the nutrients in it? I'm pretty sure as well that you don't have to start ei dosing a dirted tank that is hi tech until after the first 6 months anyways

I usually sprinkle some ferts on the bottom, before I add soil or substrate. That encourages deeper root growth. Plants will only develop as many roots as they need though, if you make the fertilizer too available right at the beginning they won't develop strong root systems.

I tend to put a ton of cheese in my pasta.

The point of MGOPS or MTS is to have a constant source of nutrients readily available to plant roots. There's no need for extra.

However, if you were using an inert substrate - kitty litter, gravel, oildri, flourite/eco, blasting sand, etc. - this would be a good idea.

+1 it's an option
Placed in a layer against the bottom glass and then covered with a thin 1/4 - 1/2" sand layer then soil or simply sprinkled on the glass then adding the soil (done it both ways) has worked without issue. Same practice as outlined setting up MTS systems. Doesn't hurt and may help although honestly can't say I saw any difference in growth.

Placed on top of the soil I feel the gas exchange would carry it into the water column through the cap to quickly.

So if I wanted, I could sprinkle some macros & micros on the bottom of the tank, then topping it with soil, then cap the soil? This process would encourage deep root growth assuming I have powerful enough light & adequate CO2 to make them want to do that.

You do need to sprinkle in the bottom of the substrate some CaCO3 or something similar to keep the pH up and supply Ca. A super acidic substrate is bad.

What about osmocote under the soil?

If you review the MTS threads adding dolomite (aids pH) and muriate of potash (potassium) along with clay (CEC & iron) is to supplement / boost the mineral support supplied. The additions are also only small amounts by volume. My thoughts on it was that it couldn't hurt so I tried it on a couple tanks. Micro and Macro additions I haven't tried.

Keep the amounts you add to just a sprinkle and (IMO) I don't see the harm.

Osmocote and like ferts come in spheres that don't dissolve, I don't hate the ferts but I hate the spheres. The density shifts as the minerals are released and once empty being almost neutral buoyancy the damn things have worked up out of the substrate on every tank I ever used them in.
Drifting around on top of the substrate like giant snail eggs.
