What Your Soil Test Tells Us
The tested soil cannot be managed as one shared amendment program for tomatoes and blueberries. The water-equivalent pH is about 5.95. Tomatoes require an upward pH correction toward their supported range, while blueberries require a substantially more acidic root zone.
More importantly, the tested native soil is not suitable as the blueberry root zone because calcium is too high and organic matter is too low for the supported blueberry suitability criteria.
| Crop branch | Released direction |
|---|
| Tomatoes | Apply 2.5 lb fish bone meal 3-16-0 + 10 lb agricultural lime per 100 ft² |
| Blueberries | Do not use tested native soil as root zone; create a separate low-calcium acidic bed and test it before correction |

Amendment Recommendations
Tomato phosphorus: Bray-1 phosphorus is low for the selected vegetable basis. Apply fish bone meal 3-16-0 at 2.5 lb per 100 ft².
Tomato pH: apply agricultural lime at 10 lb per 100 ft² on the preserved laboratory recommendation basis. Do not substitute wood ash.
Tomato nitrogen / potassium: do not invent a measured-to-target deficit from printed fertilizer guidelines. Count collateral nutrients supplied by the selected amendment.
Blueberries: do not lime, add wood ash, use fish bone meal, or import tomato-bed soil into the blueberry root zone. Build and test the separate acidic bed first.

Why These Amendments Were Selected
The tomato branch receives a conventional pH-upward correction and a supported phosphorus amendment. Fish bone meal is used for the phosphorus action while its collateral nitrogen and calcium contributions are recognized.
The blueberry branch is fundamentally different: lowering pH alone would not make the tested native soil a suitable blueberry root zone. The calcium and organic-matter evidence changes the management decision from “correct this soil” to “create and test a separate bed.”

Calculation Evidence and Safeguards
| Evidence | Released interpretation |
|---|
| Water-equivalent pH 5.94915 | Below tomato midpoint; above blueberry target range |
| Bray-1 P 7 lb/acre | Tomato phosphorus correction supported |
| Ca 5,253 lb/acre | Fails blueberry native-site suitability criterion |
| Organic matter 2.6% | Below blueberry suitability criterion |
| Missing geometry | Rates released per 100 ft²; whole-bed totals not invented |
Safeguard: tomato and blueberry targets are never averaged. Printed annual fertilizer recommendations are not represented as measured soil targets.
Final status: Released on a per-area basis; tomato and blueberry branches remain separate.
