EM•1® microbial products are available in a variety of sizes from 12oz bottles to 275-gallon mini-bulk totes. There are three main packaging choices: EM•1® Microbial Inoculant (for plants, soils, gardening, and agricultural crops), EM•1® Septic Treatment (for on-site septic and portable toilets), and EM•1® Waste Treatment (for large scale composting, odor control, bioremediation, solid waste and wastewater applications).
