EM includes bacteria that produce lactic acid. This is a strong sterilizing compound and can suppress some disease inducing microorganisms and nematode populations. It also contributes to the fermentation and breakdown of the tough cellulose and lignin. In turn the yeasts in EM produce hormones and enzymes that promote plant cell and root division. They use the amino acids and sugars secreted by the photosynthetic bacteria and plant roots and in turn give off substances which are beneficial growing compounds for the lactic acid bacteria. So all three species have a separate role to play, and help each other. They also have a symbiotic or mutually beneficial relationship with the roots of plants. So plants grow exceptionally well and root structure is significantly improved in soils dominated by these microorganisms.
The image to the upper right shows a Soyabean crop of which part had been treated with EM and a control. Most visible is the high number of fibrous roots on the EM treated plants compared with the control. This coupled with a higher density of roots shows what EM can do when applied to the soil, and the impact it can have on developing crop root structure. The images below show examples of roots (transplant trial to the right and rice on the left) treated with EM compared with an untreated control.
Below we have a trial run at a golf course which shows the impact of using EM (right) compared with the untreated control (left) on the root density.
