Soil Health

Free soil data for any location in the US. Understand your soil type, drainage, and composition before planning.

USDA's soil health assessment framework. Simple field tests anyone can run to monitor soil biological activity.

Simple soil health monitoring platform for farmers. Track observations and measure regenerative progress over time.

Chemical plus biological soil assessment. Industry standard for regenerative practitioners. Measures microbial biomass.

Laboratory soil analysis with digital results. pH, NPK, organic matter, and micronutrients comparable to university extension. Annual SOC change under improved management is ~0.01 percentage points while lab detection limits sit at 0.05-0.1 pp, so consistent multi-year testing is essential to track regenerative progress.

Continuous biological signal tracking with temperature and moisture. Real-time soil health dynamics.

Professional soil testing service designed specifically for regenerative practitioners. Biological indicators included.

The standard framework for assessing physical, chemical and biological soil health. Lab-based testing with scoring functions and management recommendations. Annual SOC change is ~0.01 percentage points against a detection limit of 0.05-0.1 pp, so the CASH protocol's multi-indicator approach (physical + chemical + biological) catches regenerative progress that carbon measurements alone miss. Widely referenced in North American regenerative agriculture.

Professional soil health tests from basic NPK and organic matter to comprehensive biological and Haney panels. 4-8 day turnaround with detailed management recommendations for gardeners and farmers. $66-$200+ depending on panel depth. Lab combustion analysis remains the gold standard for SOC measurement since field-scale changes of ~0.01 percentage points per year require precision that emerging spectroscopy methods are still calibrating toward.
