Regional Soil Mineral Profile
What’s in the Soil Around Your Horse?
Soil affects the forage your horse eats, the dust in the air, and the water moving through your property. Use the map below to explore what the U.S. Geological Survey found in the top 2 inches of soil near you.

Regional data tells you about the area. Testing helps you investigate the horse.
Hay origin, feed, supplements, water, exposure, and individual differences all shape a horse’s mineral picture. Mane Metrics helps you look beyond the regional starting point.
How the profile is calculated
U.S. Geological Survey Data Series 801, Appendix 2b: surface soils collected from 0–5 cm across the contiguous United States. View the USGS dataset.
For each element, we calculate the median of the measured locations within the selected state.
Very low is below the 10th percentile; low is the 10th–24th; typical is the 25th–74th; high is the 75th–89th; and very high is the 90th percentile or above.
When at least half of a state’s measurements are below the laboratory reporting limit, the result is shown in the very-low range without claiming an exact percentile.
Regional USGS soil data does not represent testing of your property, forage, water, or horse. Percentiles describe relative concentrations in the source dataset and do not establish exposure, absorption, deficiency, toxicity, health risk, or diagnosis. Consult a veterinarian for health concerns.
