Investigating the Benefits of Tectonite Dust as an Amendment for Bark Substrates and Dryland Crops.

This study investigates the potential benefits of using tectonite dust as a soil amendment in central Oregon. Tectonite, a rare mineral byproduct of the Warm Springs Composite Products Company, has unique properties that can enhance soil fertility and water-holding capacity. The study includes analyses of tectonite's physical and chemical properties, small-scale growth trials, and farm-scale experiments to measure grain yield.
