Field experiments and crop-focused investigations have been instrumental in evaluating the real-world usefulness of volcanic material in agricultural contexts. 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 over traditional fertilizers, improved nutrient absorption, and increased resilience and disease resistance,

Published, peer-reviewed, research at major agricultural universities (including land-grants) 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.

Established benefits include restored soil fertility, improved soil physical structure, better microbial activity, increased crop yield, and more in soils in temperate and tropical regions. Ask us about examples of published research.

Tephracor is actively engaged in and collaborating 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.
