Zone Forge reads your Utah soil test in Utah's own calibrated language — the critical levels and rate logic come straight from Utah — USU Cooperative Extension (Olsen-P + NaHCO3-K calibration), not a national average. Lime is rarely needed per Utah's alkaline-soil guidance — no automatic rate is invented.
Per Utah — USU Cooperative Extension (Olsen-P + NaHCO3-K calibration) — below the critical level, a yield response to the added nutrient is expected.
Utah — USU Cooperative Extension (Olsen-P + NaHCO3-K calibration) rates these crops in Utah:
Published source: Utah — USU Cooperative Extension (Olsen-P + NaHCO3-K calibration)
Utah — USU Cooperative Extension (Olsen-P + NaHCO3-K calibration). Zone Forge cites the publication on every recommendation.
Yes — the Utah 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 Utah lime guide rather than expecting a numeric calculator rate.
Usually not. Utah is an alkaline-soil region — Zone Forge does not invent an automatic lime rate. Review the cited guidance on the Utah lime guide; if a lab report shows unusually acid soil, confirm with the lab or local Extension before liming.
Zone Forge reads every Utah 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 →
