Worm Castings vs Fertilizer: Soil Test Results + Root Growth Comparison

See what really happens when you compare untreated soil, worm castings, Origin fertilizer, and a combination of worm castings + Origin in the same controlled demonstration. In this SoiLab demo, we track aboveground growth, root development, and lab‑measured nutrient levels to see which treatment performs best. In this video you’ll see: Side‑by‑side plant growth in untreated soil vs worm castings vs Origin vs worm castings + Origin. MySoil soil test results comparing nutrient levels of soil with and without worm castings (pH, macros, and key micros). A full root wash so you can visually compare root mass, branching, and overall root health. How biological inputs (worm castings) and OMRI organic fertilizer (Origin) work alone and together in commercially available bagged soil. If you’re trying to decide whether to use worm castings, Origin fertilizer, or both, this SoiLab trial gives you a clear visual and data‑driven comparison.
