SoilIQ – Soil Temperature

SoilIQ 2.4.0 adds Lawn Profile, Today’s Lawn Read, Air Temp, historical GDD tracking, a rebuilt guided tour, and app-wide lawn intelligence refinements.

Stop guessing. Plant by soil.

SoilIQ™ helps you know when to seed, plant, water, mow, protect, or wait using soil temperature, forecast trends, PlantAI™, LawnIQ™, activity-aware guidance, and personalized lawn intelligence.

Soil temperature drives seed germination, root growth, lawn recovery, frost risk, pre-emergent timing, watering decisions, and seasonal planning. SoilIQ helps you look below the surface.

KNOW MY LAWN

Build your Lawn Profile with grass type, sun exposure, irrigation, soil type, drainage, foot traffic, current condition, and a custom lawn name.

Today’s Lawn Read combines your Lawn Profile with soil data and forecast trends to give you one prioritized recommendation on the Today tab. Tap into the detail sheet to see why it triggered and what to do next.

AIR TEMP + SOIL TEMP

The Today tab now shows current hourly air temperature alongside soil temperature, helping you compare what is happening above and below the surface before making lawn, garden, or planting decisions.

LAWNIQ

LawnIQ™ is a soil-powered lawn advisor built into SoilIQ. It turns soil temperature, forecast trends, lawn profile details, recent lawn activity, and seasonal timing into clear guidance.

Use LawnIQ to understand:

• When to mow • When to water • When to seed or overseed • When heat stress may become a concern • When rain may change your plan • When pre-emergent timing windows may be approaching • When recent lawn activity changes what to do next

LAWN ACTIVITY & FIELD JOURNAL

Log mowing, watering, overseeding, fertilizing, aerating, pre-emergent treatments, rain, field notes, photos, and seasonal observations.

SOIL TEMPERATURE AT MULTIPLE DEPTHS

Monitor soil temperature from the surface down through deeper soil layers. Seeds germinate near the surface. Roots live below.

14-DAY SOIL FORECASTS

Plan ahead with soil temperature trends for seeding, planting, watering, frost protection, and lawn-care decisions.

HISTORICAL GDD TRACKING

Tracked crop Growing Degree Days now calculate from the actual planting date using historical weather data, not just the current forecast window.

PLANTAI FOR 130+ CROPS

PlantAI™ helps you understand crop-specific planting readiness using soil temperature, forecast conditions, frost risk, moisture signals, and timing windows.

SAVED LOCATIONS & PROBE CALIBRATION

Track conditions across your lawn, garden, community plot, farm field, or client site. Use your own soil probe to calibrate SoilIQ readings for a specific location and depth.

APPLE WATCH, SIRI, WIDGETS & LIVE ACTIVITIES

Check soil temperature from your wrist, ask Siri without opening the app, and pin readings to your Home Screen, Lock Screen, and Live Activities.

PRIVACY-FIRST
