How to make mineral-based Soil ?

Written by

Soil in Hand

Did you ever wonder what is all about minerals? How to mix and match with present soil?

Basically “make” your own soil from various natural materials, but would put a heavy emphasis on diverse mineral content in soils. Especially with tomatoes, and specifically with cherry tomatoes, Consider a form of vitamin pills to experiment with, choke your soil and plants with various types of minerals and natural hard mineral additives because plants manufacture all kinds of things, but cannot manufacture minerals.
Minerals must be given or made available to your plants for them to have them.

So far, the types of mineral media that may actually be usable by plants are:

#1 Azomite.

Azomite mineral


Have great faith in Azomite, it is very real and proven in its benefits, virtually no question about it. There is plenty of info out there about its use in the garden and even concerning benefits for animals from chickens to fish.

Pro Info: In a controlled field study using 18lbs of AZOMITE per acre (20kg/Ha), this Indonesian farmer reaped taller, broader leaves of a deep green color in comparison to shorter, thinner leaves that resulted from conventional fertilizer alone.


 #2: Pumice.  Pumice

Mostly because it is fairly soft, there is good potential for plants’ roots to penetrate and make use of what it provides. pumicite in its powdered or dust form is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. It is typically light colored. Scoria is another vesicular volcanic rock that differs from pumice in having larger vesicles, thicker vesicle walls and being dark colored and denser.

#3: Spongolite / Spiculite:

Not sure about the potential for it providing any diverse minerals or trace minerals, but its physical makeup provides lots of possibilities, including trapping other mineral additives which are essentially sold as some form of fine powder. If other powder-based mineral additives can be incorporated into this matrix, then the growing media can remain a gravel type media with the customary air gaps we like in Aquaponics.

 #4: Calcium silicate:

Has proven benefits for plants grown with it as an additive and possibly as some form of gravel, but usually available in a powder form, thus the consideration of Spongolite / Spiculite above.

It is entirely possible that this may already be a part of what Azomite has, and in fact to be honest, due to Azomite’s extreme broad spectrum of included minerals. Azomite might be the only thing needed for growing media, and anything else added might be only for ‘filler’ to compensate. For the cost of a large amount/purchase of Azomite, and that pure Azomite may not be root-burning over-kill, but over-kill just because it only takes so much Azomite to be at its most beneficial.

Search for other natural minerals that can provide anything beneficial to plants while also being practical for its cost.

One mineral have pretty much dismissed is Zeolite, because of it:
{A} Does not contribute all that much compared to other things
{B} Can be costly|
{C} has been known to have some kind of low-level radioactive quality, which is why it has been used in some filtration, but could for the same reasons be counter-productive in a living system dependent on various organisms.
