NACEN-EM: comprehensive solutions for organic agriculture

What is EM?

  • The first concept of Effective Microorganisms (EM) was developed by Professor Teruo Higa in 1991. EM consists of mixed cultures of beneficial micro-organisms such as photosynthetic bacteria, Lactobacillus, yeasts, and Actinomycetes. EM was described these micro organisms as follows:
  • Photosynthetic bacteria are specific types of bacteria that contain light absorbing pigments and they are also capable to convert light energy into chemical energy. Therefore, this group of microorganisms enriches the soil with nutrients, improving the soil very effectively. Photosynthetic bacteria are currently being used in diverse applications which consist of water purification; bio-fertilizers, animal feed and bioremediation of chemicals among many others. They are used inside the remedy the of polluted water since they can develop and utilize toxic materials.
  • Lactic acid and bacteria produce lactic acid from sugars. Lactobacillus is a beneficial bacterium that allows sterilize soil and take away byproducts which could increase and create a damaging environment. Lactobacillus helps to decomposition and disease suppression. The bacterial cycle is responsible for regulating the balance of composition in soil, to inspire existence by increasing the formation of humus. Lactic acid bacteria enhance the breakdown of organic matter inclusive of lignin and cellulose, and ferment these materials greater rapidly.
  • They play important roles in the rotation of organic matter and inhibit the growth of several plant pathogens in the rhizosphere. They produced many extracellular enzymes which can be conductive to crop production. The main contribution in organic buffering of soils, biological control of soil environments by nitrogen fixation and degradation of high molecular weight compounds like hydrocarbons in the polluted soils are tremendous traits of actinomycetes. Besides this, they are known to improve the availability of nutrients, minerals, enhance the production of metabolites and promote plant growth regulators.
  • With a diverse microbial composition, EM has been studied by many studies around the world, showing its outstanding ability to decompose organic matter, effectively improve soil, increase yield and quality of crops, and re-establish ecological balance.

What are the uses of NACEN-EM?

  • There are numerous advantage to using NACEN-EM (effective microorganisms) in agriculture With a diverse microbial composition, secreting a variety of degrading enzymes, metabolites, growth regulators, secondary active ingredients, etc., NACEN-EM Probiotics has many uses:
    – Composting manure, composting organic waste, composting agricultural waste as fertilizer.
    – Provide beneficial microorganisms to the soil, helping to improve the soil.
    – Decompose organic matter and minerals in the soil.
    – Detoxify the soil due to the use of chemical fertilizers and pesticides.
    – Kills harmful fungi in the soil.
    – Increase absorption of nutrients, increase yield and quality of crops.
  • With many of the above uses, NACEN-EM probiotics are a comprehensive solution for organic, environmentally friendly, ecologically balanced and sustainable agriculture.
  • National Center for Technological Progress – HCM Branch always brings quality products, good prices to farmers, serving organic and sustainable agriculture.
