Get your lawn
dialed in.

How much fertilizer to apply to hit a target nitrogen rate — and whether you're about to burn the lawn. Per-application calculator plus a species-matched annual program planner.

Estimate how much lime to raise your soil pH — or elemental sulfur to lower it. Enter current pH, target, soil texture, and area; get pounds per 1,000 sq ft and a split-application schedule when the rate exceeds safe per-app limits.

Exactly how much topdressing to buy — cubic yards, bags, and weight for haul planning — without smothering the lawn. Deeper leveling jobs become a safe multi-pass plan.

Know exactly when to put down crabgrass preventer. Live 2-inch soil temperature, the germination window, and your projected application date — split timing included.

Daily dollar spot disease pressure from the Smith-Kerns weather model — know when conditions favor infection so you can act before symptoms appear.

Weather-based brown patch disease indicator — see how many of the past 5 days met the Rhizoctonia temperature and humidity thresholds, so you can adjust irrigation and mowing before circular patches appear.

Load every tank exactly right — multi-product cocktails, sprayer calibration, and the partial last load nobody gets right. Plus cost per 1,000 sq ft.

Know exactly when to reapply trinexapac-ethyl. Live weather, real growing degree days, and the reapply date before rebound hits.

Make one test pass, weigh what you applied, and see exactly how far off your spreader is — plus which way to adjust the dial. No universal setting exists; this tool measures what your equipment actually delivers.

Know if conditions are right to spray right now. Live Delta T from your local temp and humidity, the preferred 2–8 window, and an honest call that wind and inversions still matter.

Turn your weekly water target into actual minutes per zone — using your system's measured precipitation rate. Catch-can helper and cycle-and-soak guidance included.

See what your lawn watering actually costs — gallons and dollars per week and per season, from your own water rate. Pairs with Sprinkler Run-Time for the minutes.

Trace your lawn on a satellite map and get an accurate square footage — the one number every other TurfDial tool needs.

How many pounds of grass seed for a new lawn or an overseed? Enter your species and area — get a low–high pound range grounded in extension seeding rate tables.
