Soil Restoration Tool SRT-1 Bundle: Includes 4", 8", and 12" tines

The SRT-1 Bundle is the complete starter kit for applying the Bison Underground Method of rapid soil restoration. Includes the SRT-1 tool plus three tines at different lengths, giving you the ability to work at different depths from day one. Make deep, wide holes in soil that allow you to place organic matter where it feeds soil biology, accelerates water infiltration, and rapidly transforms your soil from the inside out. Each hole becomes a biological and chemical restoration factory, holding moisture, providing habitat for soil organisms, and expanding outward as roots and biology colonize the surrounding ground.

The SRT-1 Bundle includes the SRT-1 soil restoration tool plus three tines: 4", 8", and 12". Drive it into the soil, pull it out, fill the conduit with organic matter. Each filled hole places biology, carbon, and water infiltration capacity directly into the soil profile, not on the surface where it bakes off or washes away, but underground where it persists and spreads. A natural complement to broadforking, composting, and no-till practices.

Designed by Dr. Steve Adams

Dr. Steve Adams is a geologist who has spent years studying how soil forms, degrades, and recovers. The SRT-1 came out of that work, a tool designed specifically for the conditions that hold soil back: compacted layers that block water and roots, hardpan that conventional tools can't penetrate, and depleted profiles that surface amendments can't reach. It is the primary hand tool for the Bison Underground Method.

The Bison Underground Method

Create deep narrow conduits in poor, compacted soil and fill them with organic matter. Each filled hole becomes a biological and chemical nucleus that improves water infiltration, hosts soil organisms, and gives roots a foothold to spread outward. Works in soil where surface treatments have failed. Learn the full method on YouTube: @BisonUnderground

Three Tines, Three Depths

The Bundle ships with 4", 8", and 12" tines so you have the full working depth range from day one. Use the 4" for shallow work, bulb planting, vegetable seedlings, and bare-root transplants. The 8" is the standard working depth for most restoration projects. Move to the 12" to place organic matter deeper into the profile as your soil improves and the tool can penetrate further. Swapping tines takes seconds. Additional tine lengths (6", 15") sold separately.
