Field experiments and crop-focused investigations have been instrumental in evaluating the real-world usefulness of enhanced weathering of volcanic material like basalt in agricultural contexts. Crop-centered research studies affirm the effectiveness of processed volcanic basalt and offer valuable insights for farmers seeking to enhance their agricultural production. Scientists have conducted trials of applications of fine grain basalt like the raw materials in TephraMax® on grains, leafy vegetables, fruits, tubers, and forage crops that consistently show 10-50% increases in yield and improved crop quality, improved nutrient absorption, and increased resilience and disease resistance in conventional and organic agricultural systems. Increases in crop yield in tropical or highly depleted soils are even larger (50-100%).

Scientifically proven benefits of EW of basalt include restored soil fertility, improved soil physical structure, better microbial activity, and increased crop yield. Published, peer-reviewed, research at major agricultural universities (including US land-grant institutions) and research centers consistently shows extremely favorable results. Crop-centered research studies affirm the effectiveness of processed volcanic basalt and offer valuable insights for farmers seeking to enhance their agricultural production.

Tephracor is actively engaged with large-scale and plot-scale trials on grain and vegetable crops in the Pacific Northwest and Upper Midwest of the United States, on nut tree groves in Oregon and California, on grains and grasslands at land grant universities in the Southeast United States, and on a research farm in Ghana.
