Micro Fertilizer DIY Formula

[wasserman]

I am thinking to create a DIY version of a micro fertz.

Is it possible to mix the below dry solution to create the DIY version of micro fertz.
- B ==> from H3BO3
- Cu ==> from CuSO4
- Mn ==> from MnSO4
- Mo ==> from H2MoO4
- Zn ==> from ZnSO4
etc

can i mix all the dry solutions into one Micro fertz solution?

it would be very wonderful if someone could share the formula

thanks

Hi,

I will give the smart folk a little more time; they probably know a better way.


Do mind sharing where you are?

Can you get a chelating agent such as EDTA or DTPA?


Then if I can think of way without being an old gasbag to explain it, I will try.

Hi

For the sake of equal distribution of knowledge, I believe being a gasbag is a wonderful thing
I live in Bali, Indonesia.
I can get EDTA chelator here fortunately.

It is quite challenging to get Micro fertz here in Indonesia with EI spec.
There I would like to create my own DIY version

I think by mixing all those chemical can be a one good micro fertz

Thanks

Hans,

Sending a shipment from the Netherlands to Indonesia costs about €17,50 (or about 22$). I have CSM+B by the kilograms, as well as KNO3, KH2PO4, K2SO4, MG7.SO4, CaNO3 etc. Let me know if you want to buy some from me, i would be happy to ship it to you, however the risk that they find the powders suspicious is yours

Regards,
Gilles

Hi Hans,

I am pleased you take my gasbag ways as they are intended, to be informational.


Having EDTA available makes it easier but chelators abound.


I have made micro fertz in the past… I never really tried putting them together like this it is rather interesting.


I am doing a bit of calculating and making sure, I can do whatever I say you should.



Do you have iron? Actually, iron is one of the easier ones to fake if necessary. Governments have yet to figure out how to ban rust.

I am assuming Epsom salts are available.

Hi Gilles
Importing CSM+B from you is one of the best options available, please let me discuss it with my folks here to have cheaper shipping cost (i hope )

I realize Bali has been pretty tight about chemical products since the bali bombing a few years ago...
However, if they do suspect me, i would ask them to taste a little bit to make sure (please make sure you put something fishy in the solution )

I'll get to you with the result gill.

Dank je wel
Hans

Hi Biollante

Fortunately, I have access to get the iron though it is Fe-EDDHA.
I am planning to ask my friend if they have Fe-EDTA, otherwise I have to mix them myself.

So, is it okay if I mix H3BO3 to get B, ZnSO4 to get Zn, etc?
Once it is okay, I will go to the next step...Calculation...

Thank you for your information
Hans

H3BO3 is also the stuff i use to enrich the CSM i get from America to make CSM+B

[nipat]

I'm in Thailand. Importing chemical fertilizers requires paper here.
Not for fear of making explosive (except urea, of course),
but mainly for protecting farmers from low quality, not up to standard ferts.
Although I think I've been hearing complaints of counterfeit ferts,
even with that regulation from time to time.

So I've been mixing my own traces mix by finding the traces mix product
with lowest Cu ratio and build from there. The lowest I could find has higer
Cu ratio than the CSM+B. So I diluted it and complemented it with other stuffs:
Fe-DTPA 7%, Mn-EDTA 13%, Epsom Salt, ZnSO4.7H2O, H3BO3,
and (NH4)6Mo7O24·4H2O.

Well, I believe if you could access to Fe-EDTA or Fe-DTPA. You're sorted then.
Because it's the only one that really needs to be chelated. If I remember it right,
the only chelated stuff in pfertz's traces is Fe, other ones aren't.

Since you're not going to build your traces mix from an existing traces mix product.
The mixing formula depends on how often you want to dose (7x a week or 3x a week).
And the percentage of your chelated Fe. And what level of each element you're aiming for.
(I'm mimicing CSM+B).

To reach the equivalent amount of nutrients from CSM+B, the whole mass of
my traces mix is considerably heavier than CSM+B. It is mainly from chelating agents.
I start to think chelating agent may add to DOM (dissolved organic matter)
and becomes bio-load. So if you can get CSM+B from aboard, that would be
the best way.

Hi Hans, All,

I was trying to do something fancy, but it got too involved.


A do-it-yourself version of CSM+B, none of the measurements are terribly critical, the Copper and Boron are the most dangerous. The EDTA serves as both a chelating agent and filler, making up 59.9% of the product (64% of CSM+B).

I have not used this myself and am just beginning tests, so obviously use at your own risk. I have done this with a couple of variations, I will get into one later, specific to Hans’ situation.


Since I started with the ingredients Hans has available that are what I used. Since the hydrates were not specified, I went with the most common hydrates.

For those concerned with sulfate, this recipe contains 10.2% sulfates, and given the quantities added to the aquarium, I seriously doubt any adverse effect. Of course, it is also providing 6.86% plant-friendly Sulfur.

Thorough mixing is the main “trick,” all full of good intentions I started with mortar and pestle and ended with TheLoudCreatureWhatSharesMySpace’s spice grinder…

This recipe results in one kilogram of product and allows for weighing in 1-gram increments a scale that reads to 0.1-gram is sufficient, as long as care is taken with the Copper and Boron, there really is not any great danger. Obviously, the recipe can be scaled (up or) down.

I found in a couple of runs that grinding, mixing and homogenizing the iron, Manganese, Copper and Zinc with the EDTA first, then adding the other ingredients seemed to work best.

Hi,

In real life Iron sulfate is easier to come by at the local garden shop.


Iron sulfate is usually available as the hepta-hydrate, FeSO₄●7 H₂O, it will appear green(ish). Heat it to 90⁰ C and it will eventually turn white(ish) to colorless and becoming the monohydrate.

Iron (II) sulfate hepta-hydrate version, a lot less EDTA.
EDTA, Ethylenediaminetetraacetic acid-------------------------------------------382-grams
MgSO₄●7H₂O, Magnesium sulfate hepta-hydrate, Epsom salt, ------------152-grams
FeSO₄●7 H₂O, Iron (II) sulfate hepta-hydrate, ---------------------------------------349-grams
MnSO₄●5 H₂O, Manganese sulfate penta-hydrate ----------------------------- 89-grams
ZnSO₄●7 H₂O, Zinc sulfate hepta-hydrate----------------------------------------- 18-grams
H₃BO₃, Boric acid-------------------------------------------------------------------------- 5-grams
CuSO₄●5H₂O, Copper sulfate penta-hydrate (blue)------------------------------ 4-grams
H₂MoO₄, Molybdic acid or dihydroxidodioxidomolybdenum------------------ 1-gram


38.2% EDTA
22.3% sulfate (7.4% Sulfur)
7% Iron (chelated)
