AgricultureBREAKING NEW GROUND...
The use of Effective Microorganisms (EM) in agriculture is opening up new dimensions. Both for organic businesses and in the conventional agricultural industry, EM is providing a wide range of possible applications.
The Effective Microorganisms promote the vitalising forces of nature and are particularly influential in the anaerobic sections of the soil and the plant. They are a great help – particularly in areas where problems with decomposition and pest infestation occur. Effective Microorganisms create an environment that represses pathogenic germs and counteracts environmental pollution. With the help of Effective Microorganisms, it is possible not only to cultivate more fertile soil and more resistant flora and fauna, but also to produce high-quality foods that are particularly rich in antioxidants. |
Studies
Testing of silage additives EM
Testing of silage additives was carried out by the Schleswig-Holstein Chamber of Agriculture (Osterrönfeld, Germany).

As the study by BOKU (University of Natural Resources and Applied Life Sciences, Vienna) shows, the spraying of EM reduces methane (CH4), ammonia (NH3) as well as nitrous oxide (N2O). It has also been proven that the TOC (total organic carbon) emissions, or the odour pressure, has decreased.

BOKU study: "Influence of EM on emissions and on potential odours during the storage of pig manure (Einfluss von EM auf Emissionen und auf das Geruchspotential während der Lagerung von Schweinemist)"
In the experimental centre of the University of Natural Resources and Applied Life Sciences in Groß-Enzersdorf, near Vienna, many months of research were conducted to establish how the addition of EM in the storage of liquid and solid pig manure effects CO2, NH3, N2O and TOC emissions. The results correspond with those of earlier experiments during the storage of liquid pig manure and in the pigsty.
• Positive effects were observed even after just one EM supplement at the beginning of the storage. In the solid pig manure, NH3emissions reduced by 43%, N2O emissions by 9% and climate relevant emissions by a total of 7%.
• The positive effects were clearly higher where FHE was fed, ensuring that EM is introduced to the livestock manure chain early and regularly.
• In solid pig manure without EM supplements, there were signs of increased aerobic microbial activities and therefore a higher temperature increase at the beginning of storage and higher CO2 emissions.

The University of Natural Resources and Applied Life Sciences, commissioned by the Bundesministerium für Land- und Forstwirtschaft (Federal Ministry for Agriculture and Forestry) researched the effects of slanted floor position on CO2, NH3, N2O and TOC emissions.
- The effects of EM in the remedy over a fattening period on CH4, NH3, N2O and climate-relevant emissions. CH4 emissions were reduced by 33% due to the use of EM. A reduction of 22% was measured in NH3 emissions. The use of EM reduced N2O emissions by around 40%. The spraying of EM in the barn resulted in a 35% reduction of climate-relevant gas emissions.
- TOC emissions were quantified as a reference to the odour emission potential of the slanted floor sty. Here, too, lower values were measured in the section with scraper manure removal than the section with glut manure removal. EM use in the section with glut manure removal led to a reduction of TOC emissions by 78%.

The consolidation of numerous university studies carried out over the years shows a comparison of one-off and long-term treatment with EM. The feed of FHE shows significant advantages in liquid cattle manure as well as liquid pig manure: the early addition of EM to livestock manure management and/or the regular use of EM achieve positive effects on ammonia and climate-relevant emissions. This protects the animals and increases their immune systems – and also the size of simultaneous cost reduction.
