I seem to remember Dr. Cho's daughter saying IMO4 to be effective cannot be mixed with other organic fertilizers. Anyone out there have an opinion on this?

Thesis Presentation by James Rushing on IMO4

lyn howe <lynho...@yahoo.com>: Sep 02 07:11PM you may already know about this but if not it might be of interst to you, might be something to discuss at the conference BestLyn     ---------- Forwarded message ---------- From: Norman Arancon <nor...@hawaii.edu> Date: Mon, Aug 10, 2015 at 6:08 PM Subject: TCBES Thesis Presentation by James Rushing To: "tcbe...@lists.hawaii.edu" <tcbe...@lists.hawaii.edu>, "uhh-o...@lists.hawaii.edu" <uhh-o...@lists.hawaii.edu>         You are cordially invited to join us for James Rushing's Thesis presentation Time: 9-11 am, August 17, MondayPlace: UCB 100 The Physical, Chemical, and Biological Properties ofIndigenous Microorganism 4 (IMO 4) Soil Inoculant and its Effect on AndisolSoil and the Growth of Corn (Zea mays)by James RushingAbstract           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.   Thesis Committee: Norman AranconBruce MathewsTheodore RadovichKoon-Hui Wang Thank you! -- Norman Q.
