Regional Soil Mineral Profile
What’s in the Soil Around Your Horse?
Explore how your state compares for six minerals and trace elements measured in surface soil.
Step 1
Select your state
Click the map or use the state menu.
The standardized dataset covers the 48 contiguous states. Alaska, Hawaii, and Washington, D.C. are not included.
Your regional profile
Six soil readings. One clear regional snapshot.
Select a state to see how its median soil measurements compare with locations across the national survey.
- Al Aluminum
- Fe Iron
- Mn Manganese
- Cu Copper
- Zn Zinc
- Se Selenium

Regional soil mineral profile
What these percentiles mean
A state percentile compares that state’s median USGS measurement with all measured locations in the national dataset. A higher percentile means a higher relative regional concentration.
The next layer
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.
The state median is ranked against all valid measurements for that element in the national survey.
Less-than results retain their known ordering immediately below the laboratory reporting limit; no precise concentration is imputed. When a state median remains below the limit, the profile shows a national band instead of 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.
