HOW DOES IT WORK
The host of beneficial microbes, including photosynthesizing bacteria, multiple strains of lactic acid bacteria, yeasts and more help break down organic matter in the soil, turning it into food for plants and releasing essential minerals like nitrogen.
In the soil, photosynthetic bacteria. have been shown to increase root growth, and produce sugars that feed other beneficial bacteria. On the leaf surface, they produce phytohormones, protective molecules that increase growth while helping plants defend against environmental stresses, reducing the risk of root rot, temperature stress, pest attack and diseases.
EM-1® was developed by agricultural Professor Dr. Teruo Higa in the 1980's and his research resulted in finding the most Effective Microorganisms® that work together to create the perfect environment for health and productivity.

FAQ's
For more answers visit our Help Center
Is EM-1® a Biofertilizer?
EM-1® is classified as a biofertilizer. Biofertilizers are natural fertilizers that consist of living microorganisms, such as bacteria, fungi, and algae. These microorganisms enhance nutrient availability and promote plant growth by establishing a symbiotic relationship with plants.
Biofertilizers also help improve soil fertility and structure over time. They promote the growth of beneficial soil microorganisms, enhance nutrient uptake by plants, and stimulate root development. This results in healthier plants with improved resistance to pests and diseases

why is my em-1 bottle swollen?
This is a result of some extra gas building up in the bottle and is perfectly normal. After all, the product is alive. The bacteria are thriving! We advise you to open the bottle slowly and let the gas blow off slowly, much like one would do with a shaken soda bottle.
