Questions about AM+PLUS Active Microorganisms and answers FAQs
How AM+PLUS Active Microorganisms work in agriculture:
The special lactic acid bacteria in AM+PLUS ensure an intact and active microorganism flora in the topsoil.
They are an essential component of our environment. They colonize all surfaces and perform various tasks, all of which are important. Some of these tasks can be completed in different ways. This applies particularly to degradation processes. Many processes tend to lead to putrefaction (slurry, manure, biogas, soils with improper treatment). However, putrefaction promotes the spread of numerous pathogens for humans, animals, and plants and creates harmful substances.
An alternative way of degradation is fermentation. Fermentation is characterized by providing high-quality, non-toxic degradation products that can be utilized by other microorganisms or other living beings. Lactic acid bacteria also play an important role in the mycorrhiza, the area around the fine root hairs of the plant. In this way, the lactic acid bacteria transfer the broken-down nutrients to the plant and simultaneously keep harmful substances away. They are, so to speak, the gateway from the soil to the plant. In addition, lactic acid bacteria break down soil nutrients, making them available to plants.
Why AM+PLUS Active Microorganisms for the Soil?
AM+PLUS is a first-class solution for soil improvement and foliar spraying. The quality of the environment created by microorganisms is particularly important for any soil quality. These microorganisms are responsible for soil fertility and quality. AM+PLUS stimulates fermentation processes in the soil, preventing the spread of harmful fungal and rot processes.
The physician, soil researcher, and co-founder of organic farming, Dr. Hans Peter Rusch, discovered these connections back in the mid-20th century. He recognized that regions with the most lactic acid bacteria in the topsoil also have the highest soil fertility. Where lactic acid bacteria predominate in the soil, the soil is healthy. Neither the formation of pathogenic germs nor smelly rotting processes occur.
Why AM+PLUS Active Microorganisms in the stable and in the manure?
Microorganisms in the stable and in the manure – The effect of AM+PLUS:
Microorganisms play a central role in hygiene, stable climate, and nutrient utilization. AM+PLUS, developed by pioneer Willi Prechtl, goes far beyond conventional solutions: This unique blend is based on an Upper Austrian placenta and contains 350 mineral and over 170 plant extracts in spagyric and homeopathic dosages. This enables AM+Plus to exert a profound effect in stables and manure.
1.
Odor reduction and better stable hygiene
While conventional microbial mixtures only contain certain putrefactive bacteria
AM+PLUS works holistically: It promotes a stable microbial environment that inhibits the formation of ammonia and sulfur gases, thus reducing unpleasant odors. In addition, the positive microorganisms colonize surfaces and
displace harmful germs, which reduces the risk of infection in the stable.
2. Optimization of manure quality
Thanks to its special composition of mineral and plant extracts, AM+PLUS accelerates the microbial decomposition of organic substances in the manure. This prevents rotting processes and ensures a more uniform consistency.
and reduces the formation of floating and sinking layers – for easier application and a more even distribution of nutrients.
3. Maximum nutrient availability for plants
The special spagyric, substance-based, and homeopathic formulation of AM+PLUS stabilizes nitrogen compounds in the manure. This minimizes ammonia losses, and the microbial microbiome is already pre-activated upon application. This means faster decomposition in the soil, improved humus formation, and a sustainable supply of nutrients to the plants.
4. Reduction of harmful stable gases
Thanks to the intelligent combination of microorganisms and bioactive
AM+PLUS plant extracts inhibit the formation of methane and hydrogen sulfide. This not only improves the stable climate for animals and farmers, but also contributes to reducing climate-damaging emissions.
With AM+PLUS, we offer a holistic solution that goes far beyond conventional microbial mixtures – for a healthy stable, high-quality manure, and fertile soils.

We are thrilled
"We searched for a while until we found microorganisms that were a good fit for Steinkraft. Now we have them! The information from over 350 minerals and 170 plants is transferred to an Austrian placenta using a special resonance process (not physical). To be precise, an Upper Austrian one, which is continually being developed and supplemented with new information in homeopathic and spagyric form.
It took some time until Willi Prechtl achieved the quality he wanted for his fields.
Now his AM+PLUS cows are produced at the Loidholdhof. Social farming – so beautiful, so soulful, so loving and mindful. And by the way: The most amazing barn I've seen in a long time, and so aesthetically pleasing there."

This is what Willi Prechtl, the pioneer of AM+PLUS Active Microorganisms, says
“The microorganisms are the alchemists in the soil, transforming insoluble rock flour into usable minerals that can then be absorbed by plant roots.
The transformation is carried out by a weak acid solution produced by the microorganisms, dissolving ionic and colloidal minerals from the rock. This is very important for the soil's humus complex and represents a major energy source for plants.

The visibly crystalline, branched structures indicate a high degree of internal order and information density—characteristics that, in spagyric theory, are considered expressions of vitality and coherence.
The image was taken under special light and clearly shows that it is not just microorganisms at work here, but a living, harmonious field.
AM+PLUS is based on an Upper Austrian placenta, enriched with over 350 mineral and 170 plant extracts – in spagyric and homeopathic forms. This complex environment unfolds a crystalline structure that is not only visually impressive but also symbolizes the quality of the product.
Customer Testimonials
A customer explains how they use AM+PLUS Active Microorganisms with Leonardite. [Great trick for easy application]
Dear Steinkraft Team, thank you very much for your fast, friendly and competent advice. You gave me a very good tip. With the AM solution, the leonardite powder can be wetted quite well, forming a kind of paste. This can then be mixed very well with the irrigation water and the clumps floating on top are gone. This is a significant relief, even if it ultimately comes down to the information that is brought along. Thank you very much for your idea and special thanks for your great products, especially for the mindset behind them. I am thrilled, already looking forward to the next - still pending - delivery and am very excited to see how my plants will grow with the new "top nutrients". Many kind regards, also to the entire team. M. O.
A customer reports: No orange snails thanks to AM+PLUS Active Microorganisms and Basalt [>> Video + Explanation]:
"I'm Helene Voit, here at home in Guttau in the Mühlviertel region. It's now mid-June, and we've completely emptied our compost bin, which we started almost exactly a year ago. I only used it this spring as primary compost soil to keep all the other raised beds, vegetable patches, flower boxes, herb beds, greenhouses, and so on, simply with a shovel. I've mixed it in everywhere, used AM+PLUS Active Microorganisms, among other things, and sprinkled lots of basalt, for the third year now. And, even though it's actually been a very wet spring, we're snail-free . That means we don't have any orange snails. Last year, we went to check for snails. This year, that's history. A few Roman snails are allowed to stay. And it's growing and thriving, and I can briefly show you what it looks like in my garden."
