About this app

🌳 OrchardPulse — a professional assistant for your orchard

The application that every orchardist in the Czech Republic needs, but no one has built yet. For growers of plums, apples, pears, cherries, sour cherries, apricots, peaches and walnuts.

🌧 SMART WATERING
• FAO-56 Penman-Monteith soil model
• Monitors water deficit in the root zone (mm AWC)
• Recommends specific dose in liters according to the area
• Tactile soil calibration — corrects the model according to reality
• Prediction: when the next watering will be needed

🛡 SPRAYING PLANNER
• Hourly forecast — finds the optimal window (wind, rain, RH)
• Product database with IRAC/FRAC codes (Mospilan, SpinTor,
Decis, Karate, Score, Coragen, Affirm, Pirimor...)
• Auto-calculation of "harvest safe" date (PHI)
• Bee warning (toxicity by product)
• Tank-volume calculator — how much product to 5/15/20/200 L
• IRAC rotation — warns against repeated use of the same group

📅 CALENDAR + DAY DETAIL
• 12 months + 16 days forecast — all days colored
by soil condition
• Daily detail: precipitation, temperature, humidity, ET₀, ±3 days trend,
phenology, active pests, spraying verdict
• Year-over-year comparison (last year + Ø 5 years + normal)
• Hourly progress with toggle T/Precipitation/Wind

🐛 PESTS + PHENOLOGY
• 7-phase phenological model according to GDD (Tbase per species)
• Per-species pest database (Plum sawfly, Fruit rot,
Aphid, Moniliosis, Vector of the cherry, Large-headed beech...)
• Biofix wizard — calibration of the GDD model according to reality
• Recommendations according to the current tree phase

🌐 DATA
• Open-Meteo (ERA5-Land) — weather + history
• ČHMÚ — auto-find the nearest station (51 stations in the Czech Republic)
• SoilGrids (ISRIC) — auto-detection of soil type from GPS
• OpenStreetMap — map pin for orchard
• Multi-source fusion: CHMI → Open-Meteo → Archive

🛡 PRIVACY (transparent)
• No accounts, no registration
• No tracking, no analytics, no ads
• Everything stays only on your phone (Hive database)
• Only lat/lon is sent from the application to the public API
• Open-source under MIT license

📚 SCIENTIFIC MODELS (no estimates)
• FAO-56 Penman-Monteith (ET₀)
• SCS-CN surface runoff
• Mills table (Venturia inaequalis)
• CougarBlight (Erwinia amylovora)
• SPI-1 (Trnka et al. 2015)
• Bee activity (Seeley & Visscher 2004)

🇨🇿 FOR CZECH GROWERS
I develop the application in my free time for my own orchard
in South Moravia. Scientific models here are not marketing
buzzwords — I plan watering and spraying myself according to them.
