Better Crops

TephraMax® promotes significant yield increases for conventional and organic agricultural systems, orchards, forests, and grasslands.

The TephraMax® Soil Amendment makes it easy and economical for farmers and landowners to increase crop yield, revitalize soil fertility, improve nutrient accessibility, and remove atmospheric carbon dioxide for better crops and a better planet. Our high standard for the raw materials that form TephraMax® remineralizes and revitalizes soils with a unique full spectrum of macro and micronutrients over multiple years. TephraMax® provides rapid bioavailability of potassium, phosphorus, calcium, magnesium and more for increased plant growth, strength, and yield. TephraMax® helps support better crops naturally.

  • TephraMax® gradually releases vital macro and micro nutrients to ensure a sustained supply to plants throughout their growth phases. The gradual nutrient replenishment of TephraMax® promotes robust plant growth and diminishes the reliance on synthetic fertilizers, promoting sustainable agricultural practices.

  • TephraMax’s® unique makeup of specific particle sizes, natural void space, and specific surface chemistry improves soil physical properties.

  • TephraMax® directly improves water management and moisture, enhancing soil water retention and curbing water loss while also aiding the restoration of depleted soils and the enduring growth of crops. Its porous structure allows it to function as a reservoir, preserving soil moisture for extended durations. By bolstering water accessibility for plant roots, TephraMax® alleviates the impacts of drought stress and aids in sustaining optimal plant hydration.  This is especially important as water scarcity is a growing concern in agriculture, particularly in regions with arid or semi-arid climates.

  • TephraMax® promotes beneficial microbial activity and enhances microorganisms diversity to facilitate nutrient cycling, disease prevention, and the decomposition of organic matter.

  • Basalt weathering releases silica which strengthes plants and makes them more resistant to damage by pests.

  • Ions released during basalt weathering buffer pH and can replace lime applications for acidic soils.

Cutting Edge Solutions For Sustainable Agriculture

We optimize enhanced weathering of basalt for agricultural benefits and is 100% natural, safe, sustainable, and made from high-quality volcanic material.

Increase Crop Yields

TephraMax ® promotes significant yield increases for conventional and organic agricultural systems, orchards, forests, and grasslands. Our high standard for the raw materials that form TephraMax ® remineralize soils with a unique full spectrum of macro and micronutrients over multiple years. TephraMax ®  provides rapid bioavailability of potassium, phosphorus, calcium, and magnesium for plant growth, strength, and improved yield.

Decreases Traditional Fertilizer and Lime Use

TephraMax ® raw materials provide a broad spectrum of essential macronutrients that improve soil health and promote plant growth, allowing farmers to reduce fertilizer application rates over time. TephraMax ® raw materials provide essential trace micronutrients that are often not delivered with traditional fertilizer treatments. TephraMax ®  balances pH and increases the pH of acidic soils, reducing or eliminating the need for lime application.

Decreases Harmful N2O Greenhouse Gas Emissions From Soil

The basalt in TephraMax ® counteracts N2O emissions associated with agricultural practices, which helps retain N in soil. The bicarbonate produced when TephraMax ® is applied stabilizes soil pH reducing the production and release of N2O. Using TephraMax® basaltic volcanic rock for soil remineralization reduces chemical fertilizer runoff through decreased use of traditional fertilizers and lime.

Atmospheric Carbon Dioxide Removal

The basaltic material in TephraMax®  permanently sequesters 300-500 kg of CO2 per ton of material applied as the weathering of basalt naturally produces soluble bicarbonate ions.

Carbon Dioxide Removal (CDR) with TephraMax®

We permanently sequester carbon from the atmosphere through science-based geological solutions that meet the highest industry standards for certification.
