<\/span><\/h3>\nCompost tea is prepared in a similar way to how the effective microorganisms (EM) mentioned above are activated. However, the source of the microorganisms is not a purchased mixture, but a few grams of compost. In water, sugar or syrup are mixed with compost and then left at 25 \u00b0 C for about a day. It is important to have a good supply of oxygen, which is ensured by blowing in the air or a stirring system.<\/p>\n
The microorganisms contained in the compost are supposed to multiply quickly in the broth. You can then use this to inoculate the soil or compost to promote biological activity. Spraying the plants with compost tea is also recommended in various Internet forums, although the intended benefit for the plants is rarely or only very superficially mentioned. Microorganisms living in the soil find no habitat on the plant and would not colonize them by themselves, which is why a positive effect initially appears unlikely.<\/p>\n
The use as a compost starter and to increase microbial activity in planting areas with a simultaneous entry of organic matter (such as mulch) can have a positive effect. This applies in particular to newly set composts in very poor soils with low biological activity. It is questionable whether it would not have at least as great an effect to spread the compost yourself.<\/p>\n
Make compost tea yourself:<\/strong><\/p>\n\n- Pour 100 liters of rain or well water into a clean container (e.g. a rain barrel). If tap water is used, it must stand for about seven days beforehand; stir occasionally<\/li>\n
- Heat the water with an immersion heater (100 to 150 W) to around 25 \u00b0 C<\/li>\n
- Dissolve 500 g of sugar beet syrup in the water, stir in 250 g of rock flour, stir in 500 g of compost or hang in a large-volume net<\/li>\n
- Switch on the pond aerator pump (if possible with a bubbler)<\/li>\n
- Leave to stand for 12 to 18 hours, then drain, filter if necessary, dilute with rain, well or stale tap water (in a ratio of 1: 5 for soil treatment, 1: 1 for compost treatment) and apply within four hours<\/li>\n
- Thoroughly clean the compost tea bin<\/li>\n<\/ol>\n

Tip:<\/strong> Since many of the described effects of compost tea and EM have not yet been proven beyond doubt, not many commercial companies in agriculture and waste management rely on one of these methods. However, larger-scale products for business are already on the market. So far, however, it has been more of an alternative approach and we would advise against relying on anything its advocate’s tout. In any case, it has been proven over years of private and scientific applications that spreading compost improves the soil.<\/p>\nSummary: where does compost come from?<\/strong><\/p>\n\n- Humus arises in various natural locations to varying degrees, it can also find its way into your garden in the form of potting soil – the best example of this is peat<\/li>\n
- Compost is always created by the activity of countless, very different microorganisms<\/li>\n
- You can buy compost at recycling yards or produce it yourself on your own compost heap<\/li>\n
- Effective microorganisms, or compost teas, are brewed to multiply beneficial micro organisms and then diluted to soil and compost. So far, however, the effect has hardly been defined or proven<\/li>\n<\/ul>\n
