:?: :idea: :?:
I was wondering what is the best NPK value for tobacco?
IF:
N - Nitrogen helps plant foliage to grow strong.
P- Phosphorous helps roots and flowers grow and develop.
K- Potassium (Potash) is important for overall plant health.

I am new to growing, but I was thinking what would be the best ratios for tobacco. (In simplest ratios)
Would something like: 2-1-3 or 3-2-4 work best?
Or would 3-1-2 or 4-2-3 be better?
In other words, what should be the highest, and lowest nutrients to feed the plants?
Thanks in Advance.

Typically 20-10-20 is used for seedlings. Once you plant outside you should use a fertilizer mix that is based on your soil test. If you have very low N levels you would supplememnt with a lot more N that you would P or K. With all that said, tobacco is like a weed. It will grow just about anywhere in just about any kind of soil. What I did a long time ago (10 yrs) was to test my soil. I took note of the levels of all the nutrients. I liked the way my tobacco grew and tasted when I had the soil test done. Whenever I get a new soil test I refer back to the original test and try to maintain THOSE levels. For instance, I like my tobacco when the N level is about 40. When I've fertilized in the past to 80 it increased the nicotine content to the point that I didn't really care for my tobacco as much (I'm a nicotine wuss).

Additionally tobacco really sucks up N and K but not so much P. Unless you are planting in a desert, try skipping the fertilizer this year and see how you like your tobacco this fall. It wouldn't hurt to get a comprehensive soil test to have as a reference for the future.

+1, ditto, all that stuff... What JBD said!
Go with what you got.
See what happens.
If you got Xtra bucks, a laboratory soil test is Very good information to have as a basis for any kind of growing.
...read all the information so you take the best sampling of your soil...

Based upon whatever test results you get, begin a process of making amendments, observe your crops, then run another test 3 or 4 years on down the road...

That's the smart way to do it.
I did not.

Best

So a 2-1-2 ratio is best for seedlings, and a 4-1-2 is good for adult plants?
If I read that reply correctly, that is the ratios to shoot for?
I realize soil tests are the most precise way to determine whats in the soil, but I was planning to mix in some bagged soil into my earth. I was looking for ratios to keep an eye out for, or even fertilizer ratios.
A 4-1-2 seems like a very high nitrogen rich soil.

It really isn't critical. Like I said, tobacco will grow almost anywhere in spite of what you do to it. I'd jsut go with a 10-10-10 or something similar and see what your results are like.
