Everything Good Grows From the Soil
Soil health isn't a single service — it's the thread that runs through everything GSS does. A lawn, a garden, a drainage swale, a farm field: each one succeeds or fails on the living soil beneath it. Understanding that soil is Todd's lifelong work.
The Science Beneath Your Feet
Todd Guerdat holds a PhD in Biological & Agricultural Engineering and spent five years as a USDA NRCS civil engineer working on soil and water. That means soil isn't an afterthought on a GSS project — it's the starting point.
Healthy soil holds the right amount of water, resists compaction and erosion, releases nutrients on its own, and grows plants that don't need constant rescue. Build on it, and everything above it lasts longer and works better.
Soil Health Across Your Property
Testing & Diagnosis
Soil testing and profile assessment to find what's really going on — pH, nutrients, organic matter, compaction, and drainage — before spending a dollar on fixes.
Correction & Amendment
A real plan based on the data: lime, nutrients, compost, and organic matter applied at agronomic rates — split across the season the way the science calls for, not dumped at once.
Living-Soil Practices
Regenerative approaches — reduced disturbance, cover, and organic matter — that build soil biology over time so it feeds itself and holds together.
One Foundation, Many Projects
Soil health is why a GSS lawn establishes, why a garden produces, why drainage drains, and why a conservation practice passes inspection. Wherever you start, the soil comes with it.
