From your first prescription to the algebra behind every rate. The docs are written alongside the code — when something changes in the app, the doc changes too.
Sign up, connect your platform, upload your first soil samples, generate your first prescription. About 10 minutes from start to finish.
Read the guideCSV and Excel formats, supported labs, shapefile boundaries, column auto-detection, the four visualization modes, soft warnings, and how interpolation works.
Read the guideUpload a soil test and get a graded report card — worst nutrient first, color- and word-coded, with variability hints and your fertility trend across past uploads. In 26 states we grade in that state university's own rating words; everywhere else we show the honest measured value and tell you why. Lime sources are mapped state by state, with live and pending methods labeled before calculation.
Read the guideA mapped land-grant source for every state — a library of 60+ extension publications, from Cornell's Morgan tables to K-State's Sikora calibration to UGA's Coastal-Plain brackets — with deep reference profiles for the Corn Belt and Mid-Atlantic (Iowa PM 1688, Tri-State 2020, Penn State) and the calibration data and citations behind every cell. 26 states grade nutrients in their own university's rating words; lime methods are labeled live or pending.
Read the guideEvery formula. Hybrid decision tree, nutrient-to-product conversions, lime engine, IDW interpolation parameters, cost-per-acre derivation.
Read the guideZone count, polygon cleanup, headland buffers, click-to-reassign, inline rate editing, the multi-year buildup planner, multi-product blends, and the stacked Litter → Potash → Nitrogen workflow.
Read the guideOAuth setup, the four-step upload pipeline, validation rules, status polling, partial-success handling, and troubleshooting.
