Agriculture – Zeolite & Lime for Vital Soils and Higher Yields

Healthy soils are the foundation of everything. Of good yields, of nutrient-rich vegetables, of an agriculture that will still thrive in 20 years. STEINKRAFT products for agriculture support your soil naturally — with the power of volcanic rock, without chemicals, in harmony with the cycle of nature

What Zeolite Does in the Soil

Zeolite is not a fertilizer in the classic sense. It is a volcanic mineral that fundamentally improves soil conditions — quietly in the background, but with a noticeable effect on every plant that grows there.

Thanks to its unique microporous structure (= full of tiny cavities like a miniature labyrinth), zeolite stores water and nutrients and releases them exactly when the plant needs them. Not all at once, not leached into the groundwater — but gradually, plant-friendly, sustainably.

For your farm, this means: less fertilizer use, better nutrient utilization, more resilient plants — even during dry periods.

Zeolite in the Field: What Studies Show

The ECO-ZEO project demonstrated in extensive field and laboratory studies: Plants in zeolite-containing soil showed better health, higher yields, and reduced susceptibility to stress. Zeolite improved water retention, increased nutrient availability, and made the soil more resilient to environmental stressors.

Zeolite binds nitrogen (NH₄⁺) in the soil and prevents its leaching into groundwater. This nitrogen is then available to plant roots exactly when they need it — a natural long-term fertilizer. At the same time, zeolite increases the ion exchange capacity (= the soil's ability to absorb and store nutrients) and promotes soil life.

Dr. Peter Ost, zeolite pioneer, explains it this way:

"In the combination of lime AND zeolite, I have optimal conditions to support the plant — on the leaf and in the leaf. Zeolite doesn't release everything at once and overwhelm the plant, but does so gradually."

FAQs

Does zeolite replace fertilizer?

No – zeolite does not replace fertilizer, but it does make fertilizer more efficient. Nutrients are bound in the soil instead of being leached out, and are slowly made available to the plant. This means less fertilizer for the same effect.

Is STEINKRAFT organically compliant?

Yes. All our agricultural products can be used in organic production in accordance with VO (EU) No. 2018/848. For exact classification, we recommend consulting your organic inspection body.

How do I apply zeolite to the field?

Work in BODENKRAFT PUR directly with a seed drill or spreader. Apply GRÜNKRAFT to the leaves via field sprayer or drone. Apply AM+PLUS to irrigation water, slurry, or via foliar spray.

What our customers say — Practical experience

The best theory is the one that works in the field. What farmers and gardeners experience with STEINKRAFT products

"We discovered rock dust through the humus movement. And you can tell that things are happening—mostly in the grassland where we spread the slurry. I can clearly see the difference where the slurry doesn't go."

"I also started feeding zeolite to the animals. We directly market yogurt and curd cheese—and everyone says the taste is unique, there's no better milk."

"For potatoes this year, we used GRÜNKRAFT CALCIUM foliar fertilizer and AM+PLUS Active Microorganisms—and had no potato beetles. The plants stayed green 2–3 weeks longer than all the farms around us. We also had zero wireworms."

"From 2,000 m² of field area, we harvested 5 tons of potatoes. That really thrilled us. We were also simply thrilled with the kohlrabi—we harvested football-sized fruits that weren't woody."

Bernhard and Helene Keplinger, Organic Farmers, Bad Leonfelden, Upper Austria ⭐⭐⭐⭐⭐

"Initially, we started with other microorganisms. We worked with them for 3 years—the slurry didn't really change. Then we found AM+PLUS from STEINKRAFT. Since then, the climate in the barn has improved tremendously. The smell of the slurry is better, stirring is much easier, and we no longer have flies in the barn."

Bernhard Keplinger, Bad Leonfelden ⭐⭐⭐⭐⭐

"I swear by the basalt, zeolite, and AM+PLUS microorganisms. My apricot tree has recovered very well; it has new leaves. My blackberries are stronger than my neighbor's. I've never had such beautiful, strong cucumbers and tomatoes in the greenhouse. The Hokkaido squash and zucchini are stronger."

Traudi Wahlmüller ⭐⭐⭐⭐⭐

"This year, I achieved incredibly great results with my plants using two products from the STEINKRAFT line. Result: significantly stronger growth and more vibrant foliage, a larger quantity of fruits and vegetables, no fungal infections. I am thrilled!"

Was die Wissenschaft sagt

Boden & Wasserspeicherung: Studien des ECO-ZEO-Projekts zeigen: Zeolith verbessert die Wasserspeicherung im Boden messbar und macht Nährstoffe effektiver pflanzenverfügbar — besonders wertvoll in Trockenperioden.

Pflanzenwachstum: Pflanzen in zeolithhaltigem Boden zeigten in Versuchen bessere Gesundheit, höheren Ertrag und signifikant mehr Blütenbildung als Kontrollpflanzen.

Stickstoffbindung: Zeolith bindet Ammonium (NH₄⁺) im Boden und reduziert Stickstoffverluste — weniger Auswaschung ins Grundwasser, mehr Nährstoffe für die Pflanze.

Umwelt: Im Vergleich zu konventionellen Düngemitteln reduziert Zeolith den Nährstoffeintrag in Wasserquellen deutlich — nachhaltiger Umweltschutz ohne Ertragseinbuße.
