EM-1 Microbial Inoculant
Liquid, available in pint and gallon sizes.
From the manufacturer:
EM® is an acronym for Effective Microorganisms®. EM® is a brand name referring to a family of microbial-based products using a technology developed by Japanese scientist Dr. Teruo Higa. The main product, EM·1®, is a liquid bacterial product comprising three groups of microbes: Yeast, Photosynthetic Bacteria, and Lactic Acid Bacteria.
EM•1® Microbial Inoculant accelerates the soil building process and promotes beneficial soil microbe communities. The soil building process revolves around soil aggregate formation. Soil aggregates form as mineral and decomposed organic matter particles are bound together by soil organism secretions that act as glues. Stable and well-formed soil aggregate is the key to overall soil function. EM•1® produces high levels of polysaccharides and other beneficial organic acids and enzymes in the soil that help build stable aggregate and soil structure. Increased aggregate stability prevents the pore spaces between the aggregates from collapsing during heavy, saturating rains and reduces compaction caused by machinery. Furthermore, improved soil aggregate stability reduces soil erosion and run-off. Soils are better able to absorb and retain moisture, as well as cycle nutrients.
Soils rich in organic matter such as beneficial soil microbes and that have been treated with organic fertilizers will require significantly less EM•1® than soils with low organic matter and those that have been treated with conventional synthetic fertilizers.
