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

EMRO, the company and technology behind Effective Microorganisms®, has been the global leader in the development of beneficial microbes and fermentation since the 1960's. 

EM･1 is the original and authentic Effective Microorganisms® formulated by Prof. Dr. Teruo Higa.

EM-1® is a revolutionary product that helps improve the quality of soil. The host of beneficial microbes, including photosynthesizing bacteria, multiple strains of lactic acid bacteria, yeasts and more help break down organic matter in soil, turning it into food for plants and releasing essential minerals like nitrogen.photosynthetic bacteria. In soil, they've 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.

No you do not need to activate EM-1® to use it.

EM-1® is a concentrate that is ready to use straight from the bottle. See dilution rate card for instructions.

Activated EM-1® provides an even more economical way to use EM-1®. Activation takes 7 days and additional materials are required. 

When using Activated EM-1® , follow the same dilution rates as EM-1®
