NPK Ratios Of Different Plants - And Advise

It seem to be hard to find what NPK ratios a lot of different plants need. Some are easy and probably on this list but Googling has lead me nowhere on most of these.

FOR COMPANION GARDENING

Sweet Corn
Tomatoes

I want to add amendments to each raised bed planter and condition the soil. I am making 4x8 planters about 16-24" deep this year for my garden. It's on a slope so I have to make raised beds. I am getting free mulch compost from the city where I live. You can just have them dump it in your truck bed.


If I can come up with enough money this would be my dream garden

Large Grade Perlite (One 50L Bag Per Planter)
Vermiculite (4cu ft per planter)
Coco Coir (10lb per planter)

Dolmite Lime
Coffee Grounds
Bone Meal
Blood Meal


(MAYBE)
Neem Meal
Karanja Meal
======

Maybe if someone can point me in the right direction of what to plant together for proper nutrient management per planter.

Corn Will have it's own 4'x8' planter

Forget the coco and the vermiculite. no perlite either. we don't generally use those things outside of containers. rather, use as much organic matter as possible by volume for each raised bed.
I like city compost also but I need to know what's in it before I plant anything that i'll be feeding my family. if you're referring to leaf compost then use as much as you like without worrying. if it's composted sewage then you don't want it for vegetables bc of the heavy metals that can't be filtered out. use that soil amendment for ornamental plants only. also, you can probably get an analysis for the city compost from the city. Tell them you're planting veggies and need an analysis of their product.

As to companion planting, I'm a grouper and I'd keep the mints together in a bed and I'd also plant the mints in containers that were set into the soil bc of their way of propagating themselves. They run by stolons and you want to keep them from getting away from you otherwise they'll be everywhere.
Keep the tomatoes in their own bed. They are heavy feeders. By contrast mints and dill need little fertility.
Obviously you don't want melons growing with your berries so keep them separate.
As these things are harvested plant cover crops to keep the soil from eroding and to put more fertility into it as possible.

As to NPK figure that most plants like what's called MFW soil. Moist, Fertile, Well drained. Exceptions to that are the mints which actually prefer less fertility but don't get too caught up in that.

While your building beds make yourself a compost area. Put the coffee grounds and other vegetable refuse in it and add the lime and other things and let the whole thing mellow over time before you use it.

I think I covered everything. If I missed something just hmu. okee dokee?
