For a Wayne County garden fertilizer question, start with a laboratory test of the growing area—not a soil-map label. For an initial view of mapped soil types, start with the county GIS or USDA Web Soil Survey. Wayne Soil and Water Conservation District links both kinds of resource, but they answer different questions. District directory
Choose the evidence before collecting it
| Question | Useful starting point | What remains unmeasured |
|---|---|---|
| Which soil units are mapped around this property? | WayneCoOH Soils layer in the county GIS | The current nutrient condition of a particular bed |
| What mapped interpretations cover a selected project area? | USDA Web Soil Survey, with an area of interest drawn around it | Site conditions that require on-site investigation |
| Does this lawn or vegetable bed need a nutrient adjustment? | A laboratory sample representing that growing area | Conditions in other areas that were not sampled |
| Could imported fill or past land use have left contamination? | Ask a laboratory about a separate contaminant analysis | A routine fertility panel is not a comprehensive safety clearance |
The comparison is LSL’s synthesis of the District’s routes, USDA’s planning limits and Ohio State’s explanation of test selection. It is not a soil survey or a diagnosis of a property. District · USDA · Ohio State
Save a map that shows what you searched
Wayne SWCD describes searching an address in the county auditor’s GIS and using the WayneCoOH Soils layer. For USDA’s service, define the area of interest first, then open the Soil Map and explore the relevant soil information. USDA also offers printable reports. Save the boundary with the output; a neighborhood-wide selection is not the same as a garden-bed observation. District instructions · USDA workflow
USDA calls the survey useful for general planning and warns that some applications require on-site investigation. A mapped interpretation alone should not settle a drainage, foundation or septic-design question. Wayne SWCD no longer distributes paper soil surveys. USDA limits · District availability
Divide the yard before filling a sample bag
Ohio State advises separate tests for different plantings, management histories or soil conditions. Don’t mix the vegetable bed, lawn and persistently wet corner into one bag simply because they share an address. Contact the selected laboratory first for its kit, requested analyses and instructions. Within each chosen area, collect equal-depth, equal-volume subsamples in a random zigzag pattern and combine them as directed. Remove surface debris; use a clean plastic container. Dry and package the sample according to the lab’s instructions, and match the bag identifier to the form. Ohio State sampling guidance
Use this small handoff card for each bag:
- Area: a sketch or description specific enough to find it again.
- Purpose: plants being grown and the question the laboratory should address.
- Collection: date, depth and locations represented by the subsamples.
- Order: bag identifier, requested tests and the matching laboratory form.
The card is LSL’s organizational aid, not a laboratory’s required form. Keep the resulting report with that area record before discussing treatment quantities. For a symptomatic plant that needs identification rather than a fertility panel, see the Wooster plant-clinic routing guide.
LSL reviewed the cited public instructions on September 20, 2026. No parcel query, soil collection or laboratory test was performed; current laboratory prices and turnaround times were not checked. The District’s link labeled as Ohio State sampling guidance currently points to a California soil-resource destination, so the source list below provides the directly checked Ohio State fact sheet instead.
