The Physical, Chemical, and Biological Properties of
Indigenous Microorganism 4 (IMO 4) Soil Inoculant and its Effect on Andisol
Soil and the Growth of Corn (Zea mays)
by James Rushing
Abstract
Since 1997, many farmers across the world have adopted techniques of an agricultural system called Natural Farming, which utilizes indigenous microorganisms and naturally derived soil amendments to improve soil dynamics and plant production. However, due to a dearth of peer reviewed reports that exist on the subject, many stakeholders and researchers have been hesitant to use these sustainable techniques. The most widely discussed and utilized Natural Farming amendment is Indigenous Microorganism 4 (IMO 4), which is a form of indigenous microorganism inoculated compost made from agriculture by-products, high in carbohydrates, and a moderate concentration of plant available nutrients. Because of this lack of scientific data discussing the use of IMO 4 as a soil bio-stimulant, a series of experiments were designed and implemented to analyze the physical, chemical, and biological properties of IMO 4, as well as examine the effect of IMO 4 on soil dynamics and the growth of corn (Zea mays) in Andisol soil, when compared to various other organic amendments.
It was determined that IMO 4 was rich in indigenous microorganisms and possesses a moderate concentration of plant available nutrients. The physical, chemical, and biological analyses of IMO 4 indicated a potential as a soil bio-stimulant if the indigenous microorganisms survive inoculation. A greenhouse experiment comparing IMO 4 to organic matter applications showed IMO 4 had a similar effect on soil dynamics and the growth of corn as the application of organic matter. A further experiment examining the effect of IMO 4 in conjunction with organic fertilizers showed that IMO 4 had similar impact on soil dynamics as organic matter amendments, due to the substrate effect of IMO 4 applications. Organic matter amendment applications also showed a significantly greater effect to plant height, dry weight, and total leaf area than the IMO 4 samples. There was no evidence the indigenous microorganisms on the IMO 4 substrate survived inoculation into the soil environment. It was concluded that IMO 4 was effective in adding organic matter and plant available nutrients to the soil via a substrate effect. Due to the lack of effect IMO 4 applications have on plant growth and the absence of significant improvement to plant production, organic matter amendment applications in the form of composts and mulch are recommended.

This appears as though it
will be a hot topic in this group. But I am not sure if I have it all
right.
To sum this up, the last sentence of the thesis abstract states:

"Due to the lack of

significant improvement to plant production, organic matter amendment
applications in the form of composts and mulch are recommended."
Let me get this into laymen's terms - IMO 4 (an inoculated form of
organic matter) did not work better than other forms of organic matter,
in fact it did worse. Therefore, don't bother with IMO 4, just regular
old compost or mulch works better.
Is that about right?
I am sure that in the details of the project there is much more information of value, but just on taking the face value of the abstract, it appears that for this study no redeeming values were found by the author to justify the use of IMO 4 amendments.
I am sure there will be some interesting discussions to follow.
A great follow up research project might be:

Production parameters of IMO 4 and their
effect on the absence or abundance of mycorrhizal fungi.

Aloha Ka Kou,
When we use IMO4 for soil foundation
First we put IMO4
Add biochar then soak it with soil treatment solution.
Add biochar then soak it with soil treatment solution.
Wait one week then apply SOS(soil treatment solution) again.
Waite one more week then ready to plant.
If you miss these step may not work.
Also when we make mixed compost with IMO4
We add Natural Farming inputs.
If you do not know KNF system please do not included with your experiment.
Thank you, Kim
