Default Plant Talker and Nutrient Deficiencies

If I wanted to learn how to look at my plants to develop an idea of what is missing in my soil and what the plants need. Is there a book I can buy or a place I can go to develop these skills? I need to learn from a "plant talker."
How many of the growers here know how to decide what to feed their plants based on how they look? I know one person who says his plants tell him what they need. He never gets a soil test, grows organically and has fantastic results. He is unwilling to disclose his secrets.

That's because he has no secrets. In soil it's fairly simple. Add fertilizer, water, and make sure you keep diseases and pests away if possible and needed.
Haifa and now Yara have some decent guides to deficiencies, but I feel like there is still a lot more to improve on these guides (as I have learned after starting to grow without soil). You will almost never run into them in normal decent soil, the only one you might encounter is iron deficiency which is quite easy to see.

If you ever see some great plants and think, what is that guy doing that his plants look so good, 90% of times is because he uses more fertilizer.

We send leaf samples to Servi Tech in Kansas for leaf analysis. We no longer have to guess.

Leaf analysis sounds pretty solid to me.

Lubadub, There is a 3 volume set titled "The Garden doctor" by Jacob Mittleider that addresses how to diagnose and treat nutritional deficiencies in plants. It was one of the first I purchased when I got into growing tomatoes.

Ami, thank you. The book really looks interesting. Has it been of real value to you? Are you growing organically?. Do you get soil tests done? Have you ever done tissue analysis as was suggested here in an earlier post?

The Books have a wealth of information. 3 volumes covering the Macro and Micro nutrients and for each nutrient it explains the chemistry of and the plant symptoms for deficiency and excess for the given nutrient. It also gives you a list of Inorganic and organic ferts you can use for the particular nutrient you want to supplement.
As far as my growing methods I grow in containers, raised beds and some times in soil. I use Microbial Biofertilizes (microbial inoculants) added to the growing medium to improve soil Fertility and disease control.
I don't use tissue analysis as I never had the need which is used mostly by commercial/Greenhouse growers who use hydro feed systems.

Here are a couple books that might interest you.

Nature Farming and microbial Applications. Hui-lian PhD

Handbook of Microbial biofertilizers. M.K. Rai

They are listed at Amazon.de
