Ideal N, P, K and PH

[whoose]

How about the ideal (optimum) ratio and some ferts that might approximate the ratio.

Depends on who you listen to. The 2-1-3 school, or thereabouts, has my ear these days.

It depends on what your soil has in it for the ideal ratio of fertilizer.

As for the pH I feel around 6.5 is just about perfect.
I am not a fan of the low nitrogen high P and K tomato fertilizers in my soil.
I have read and seen where after years of use soil tests come back too high in the latter and to low in nitrogen.
But this is something everyone needs to figure out in there own soil.
I like the Plant Tone 5-3-3.

Depends on who you listen to is right. Organic or synthetic?
Optimal PH between 6.0-7.0 in most cases.

Las winter I did a soil test. What I found out reinforces my previous thinking :

P and K accumulate after years of fertilizing. As they stick to the soil.
N , being readily water soluble, leaches down/out and away from the plants' reach. That is why it has to be supplied in a continuous fashion. This is more true when there isn't enough organic matter in the soil. Organic matter tend to regulate the amount of available N, by absorbing and releasing it gradually.
On the pH: Tomato and most garden veggies thrive in a pH range of 5.6 to 7.0 . But most of them prefer a slightly acid soil. The expert define it a pH = 6.8 (ideal). My own garden beds have pH from 6.o to 6.5. That is just fine with me.
a sample report. As reported N is way down. B/c I stopped fertilizing from September on and we got lots and lots of rain for months, washing down the N.
