Nevada'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. UNR Cooperative Extension does not run a soil-test lab and refers Nevada producers to regional labs. Zone Forge's Nevada source uses the University of Idaho's Southern Idaho fertilizer guides — an Olsen-P framework for calcareous soils, climatically matched to Nevada's irrigated valleys — with the citation on every number. Lime is rarely needed on Nevada's alkaline soils; Zone Forge does not invent an automatic rate.

Yes — the Nevada 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 Nevada lime guide rather than expecting a numeric calculator rate.
Usually not. Nevada is an alkaline-soil region — Zone Forge does not invent an automatic lime rate. Review the cited guidance on the Nevada lime guide; if a lab report shows unusually acid soil, confirm with the lab or local Extension before liming.
Zone Forge reads every Nevada 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 →
