About EM

EM is a sustainable microbial inoculant that achieves synergistic effects by combining beneficial microorganisms which exist in nature. EM activates local and native microorganisms that live in soil and water to boost performance. One of the strengths of EM is that it is a diverse combination of microbes, and this gives it versatility in terms of a wide scope of applications that it can be used on. EM was initially developed to improve soils and enhance crops but has evolved to benefit a wide range of areas and is used in numerous fields including agriculture, animal husbandry and environmental purification in more than 100 countries around the world.

An application EM had a dramatic impact on remediation of the soil and improving the crop.

The Role of Soil Microbes in Chemical Fertility

Application of ammonia based fertilisers can adversely affect soil health by depleting humus and soil organic matter, and creating unfavourable conditions for microbes to grow and function. However, using Microbial inputs alongside fertiliser can go along way to mitigating these issues while also helping to change chemical fertility through increasing biological activity.
