Wyoming's extension doesn't run its own soil-test calibration lab; it refers growers to neighboring-state methods. Zone Forge uses that published referral and discloses it in-app — no pretend precision. Wyoming has no land-grant fertilizer tables of its own — UW Extension points producers to regional certified labs. Zone Forge's Wyoming source is built on the neighboring land-grant calibrations those labs use: Colorado State for the eastern plains and Montana State's EB0161 for the Bighorn Basin and mountain valleys, both Olsen-P frameworks for calcareous soils. Every number keeps its original citation so you can verify it. Lime is rarely needed on Wyoming's alkaline soils; Zone Forge does not invent an automatic rate.

Yes — the Wyoming soil-test recommendation calculator is free and needs no signup. Enter your lab values for source-cited P and K. Lime is advisory only here — see the Wyoming lime guide rather than expecting a numeric calculator rate.
Usually not. Wyoming is an alkaline-soil region — Zone Forge does not invent an automatic lime rate. Review the cited guidance on the Wyoming lime guide; if a lab report shows unusually acid soil, confirm with the lab or local Extension before liming.
Zone Forge reads every Wyoming soil test in its own state's language, then builds source-cited fertilizer and alkaline-soil lime guidance (no automatic rate) and full variable-rate prescriptions. See the science →
