Using EM to Improve Soil Health and Performance
EM works by getting the natural processes to function, the way nature intended by stimulating biological activity in the soil. Using EM will improve soil health and yields and enhance fertiliser performance.
EM will not only add to the microbial population, but will also stimulate resident microbes. This stimulation can lead to increasing the resident nitrogen fixation capacity directly through the increase of N fixing bacteria, and indirectly by increasing clover growth, increasing mycorrhizal activity and other fungal and earthworm activity.
EM will enhance growth and improve soil health through:
- Enhancing fertiliser inputs
- Fixing atmospheric nitrogen
- Converting organic matter to plant nutrients
- Decomposing organic residues
- Recycling soil nutrients
- Breaking down fertiliser compounds
- Improving root structures
- Breaking down pollutants in the soil
- Increasing earthworm numbers
- Reducing compaction issues
Improved Organic Matter Breakdown
EM will help the decomposition process of organic materials, and during fermentation will produce normally unavailable organic acids, such as lactic acid, acetic acid, amino acid, malic acid and bioactive substances and vitamins. A key ingredient in this process is organic matter which is supplied by pasture residuals, (dead matter) recycling crop residues, green manures and animal manure. In addition, this process leads to increased humus in the soil enhancing fertility and soil health. Earthworm numbers will also increase with the use of EM to further aid soil health and performance.
Enhancing fertiliser inputs
The microbes in EM® will solubilise compounds both organic and inorganic that are largely unavailable to plants and make them available for uptake by the plants root system allowing the plant to put more energy into growth. In performing this important function the Microbes create a more efficient use of added nutrients, generating a better growth response from fertiliser inputs. Also, our research has demonstrated the ability to lower fertiliser use while still gaining the same yield. Research has shown the microbes in EM® stimulate Mycorrhizae and Trichoderma further enhancing nutrient uptake and the plants root system. EM® works effectively with most fertiliser and can be sprayed on with most pesticides and herbicides decreasing your application costs.
EM works firstly through effective organic matter recycling which builds humus, the food for your soil and plants. It will also enhance fertiliser and nutrient breakdown in the soil and uptake by plants, will give improvements in nitrogen fixation and stimulate micorrhyzal activity.
This has two main functions, firstly it creates better growing conditions and this leads to a stronger healthier plant. Secondly it provides competitive exclusion, which means that it out-competes pathogens for space, by inoculating the leaf surfaces with beneficial microbes. The cumulative effect of all of these functions is a higher yielding crop.
The graphs on the right show the impact EM can have on yield.
Building Soil Humus
EM efficiently breaks down organic matter into stable humus, a key component to aggregate formation, by reducing oxidative forces that primarily rob the soil of Carbon and Nitrogen in the form of methane and ammonium gases, respectively. This is achieved from a reduction of available Hydrogen ions due to a favourable change of organic acid composition and concentration in the soil. The result is that a greater amount of organic matter is converted to humus, aiding in aggregate formation.
Improved Root Structure
This was shows the difference between a paddock of clover treated with EM and one without. The main differences and the improved root structure and many nodules on the treated paddock. There was also a much better breakdown of organic matter in the soil.
EM's Impact on Soil Compaction
EM will support the growth of other beneficial organisms like mychorrizae, worms, and insects already in your soil, bringing nature back into balance.
It will also produce lots of polysaccharides - glues that hold the soil together and hold in moisture, improving drought resistance.
A healthy soil and stimulated biological activity help build stable aggregate and soil structure. Increase aggregate stability prevents the pore spaces between the aggregates from collapsing during heavy, saturating rains and reduces compaction. Improved soil aggregate stability reduces soil erosion and run-off. Soils are better able to absorb and retain moisture, as well as cycle nutrients.
Low Cost Bio-Stimulant
For large scale use we recommend using our EM Soil and Crop product. This is our expanded ready to use product and is the most cost effective way to use EM. It can cost as low as $2.50 per litre depending on volume purchased (please contact us for volumes in excess of 200 litres). We recommend using 15-20L per hectare when using EM by itself or 5-10L per hectare when used in conjunction with other nutrients.
Please contact us for more information on how to make EM as cost effective as possible.

This is a study which aims to assess the effect of EM application on the composting process of rice straw with goat manure and green waste and to evaluate the quality of both compost treatments. There are two treatment piles in this study, in which one pile was applied with EM and another pile without EM. Each treatment was replicated three times with 90 days of composting duration.
This trial published in the Polish Journal of Natural Sciences in 2008 looked at the Effect of fungal infection and the application of the biological agent EM1 on the rate of photosynthesis and transpiration in pea (pisum sativum l.) leaves.
Earthworms are one of the most important organisms in soils. Earthworms mix together different layers of soil and incorporate carbon in the form of organic matter into the soil. It’s within this process of mixing that disperses the organic matter throughout the soil and makes the nutrients held in it available to plants.
The importance of plant development in increasing crop yield potential has become more and more evident since the beginning of the green revolution, since then there has been considerable work done to enhance these developmental traits which has led to improved crop performance. The diverse range of microorganisms found in the soil food web produce substances that regulate plant growth
This family run is the pioneer of no tillage farming in the Parana state in Brazil. The Uemura family started with soybean cultivation applying conventional farming methods. However, they realised that the yield was decreasing due to soil erosion while the cost for agricultural inputs were rising, making farming more unfeasible. Because of this they decided to implement the no tillage system
Over the past decade we have had many of our customers changing their systems/rotations to include No-till/minimum till systems or moving towards regenerative pastures for their environmental and economic advantages. No-till systems have the potential to offer benefits over more traditional intensive tillage systems,
