Microbial inoculant from commercial EM-1
Inoculants Bio-inputLiquid inoculant that brings a large population of fermenting microorganisms to the soil and organic matter.
Application description: To the soil, diluted in irrigation water or with a watering can; also to activate compost, bocashi and growing beds.
Dose: Indicative (manufacturer): 190 to 375 litres of activated EM per hectare per year, in 4 to 8 applications, diluted in irrigation water.
Mother EM cannot be made at home: it is a commercial culture whose strains are not published; here it is only multiplied. For a fully home-made inoculant, see Mountain microorganisms or Indigenous microorganisms (IMO). Keep to the proportions: other doses give poorer results. Do not re-multiply from activated EM (it degrades). Ideally use within 35 days, at the latest within 65; store cool and shaded, never frozen. If it smells rotten or the pH rises above 4.5, discard it. Do not mix with chlorine, copper or fungicides.
1) If using tap water, leave it uncovered for 24 hours so the chlorine evaporates. 2) Dissolve the molasses in part of the warm water. 3) Pour into a clean 20-litre drum, add the rest of the water and then the mother EM; shake. 4) Fill the drum almost to the top (little air) and close it. 5) Keep it in the shade at 17 °C or more; open the cap every 1–2 days to release gas. 6) It is ready around day 7: pleasant sweet-sour smell, colour turned from dark brown to orange-brown, pH between 3.2 and 3.8.
7 days of fermentation (longer in cold weather).
Orange-brown liquid with a sweet-sour smell.
