Current solutions are fragmented or paid, limiting accessibility.\n\n---\n\n## 🔹 Solution\n\nA **monolithic Next.js app** (with Leaflet maps + API routes) that:\n\n- Collects weather + soil + historical yield data.\n- Runs **rule-based models** (and ML later).\n- Predicts crop cycles \u0026 irrigation schedules.\n- Delivers guidance via **dashboard + SMS/email export**.\n- Uses **free-tier APIs** and **open datasets** to remain cost-free initially.\n\n---\n\n## 🔹 Techstack (Minimal)\n\n- **Frontend/UI** → Next.js (monolithic app) + TailwindCSS.\n- **Maps** → Leaflet.js (free + OSM tiles).\n- **Database** → Supabase (free Postgres + Auth + Storage) or SQLite (self-hosted MVP).\n- **APIs** → Next.js API routes (server-side logic).\n- **ML/Models** → Rule-based irrigation engine inside Next.js API routes (optional Python FastAPI microservice later).\n- **Notifications** → Email (free via Resend / Gmail SMTP), SMS (skip for MVP).\n\n---\n\n## 🔹 Free APIs \u0026 Links\n\n### 🌦 Weather APIs\n\n- **Open-Meteo (Free, No API Key)** → Weather forecast \u0026 historical data. 🔗 [open-meteo.com](https://open-meteo.com/)\n- **WeatherAPI (Free tier)** → More detailed forecasts. 🔗 [weatherapi.com](https://www.weatherapi.com/)\n\n### 🌱 Soil \u0026 Crop Data\n\n- **SoilGrids (ISRIC)** → Global soil properties. 🔗 [soilgrids.org](https://soilgrids.org/), API: [rest.soilgrids.org](https://rest.soilgrids.org/)\n- **FAO AgroDataCube** → Open agri datasets. 🔗 [data.wur.nl](https://data.wur.nl/datasets/agrodatacube)\n\n### 🛰 Remote Sensing (optional)\n\n- **Sentinel Hub / EO Browser** → NDVI, crop health. 🔗 [sentinel-hub.com](https://www.sentinel-hub.com/explore/eobrowser/)\n- **Google Earth Engine** → Free satellite analytics. 🔗 [earthengine.google.com](https://earthengine.google.com/)\n\n### 📍 Maps / Geocoding\n\n- **Leaflet.js** → Free map rendering. 🔗 [leafletjs.com](https://leafletjs.com/)\n- **OpenStreetMap Tiles** → Base map. 🔗 [openstreetmap.org](https://www.openstreetmap.org/)\n- **Nominatim** → Free geocoding. 🔗 [nominatim.org](https://nominatim.org/release-docs/develop/api/Search/)\n\n### 📊 Market Prices (India)\n\n- **Agmarknet** → Daily mandi prices. 🔗 [agmarknet.gov.in](https://agmarknet.gov.in/)\n\n### 📤 Communication\n\n- **Resend (Free Email API)** → Farmer reports. 🔗 [resend.com](https://resend.com/)\n- **Gmail SMTP** → Free email via Gmail. Docs: [support.google.com](https://support.google.com/a/answer/176600?hl=en)\n\n---\n\n## 🔹 Core Features (Monolithic Next.js MVP)\n\n1. **Farmer Dashboard**\n\n   - Leaflet map (draw/select farm location)\n   - Weather forecast widget (Open-Meteo)\n   - Soil profile (SoilGrids API)\n\n2. **Crop Cycle Prediction**\n\n   - Planting → Harvest timeline (crop type + weather)\n   - Seasonal suitability suggestions\n\n3. **Irrigation Scheduling**\n\n   - Rule-based (crop coefficient + evapotranspiration)\n   - Calendar of irrigation dates/amounts\n\n4. **Yield History Upload**\n\n   - CSV upload (Supabase Storage)\n   - Visualize yield vs weather patterns\n\n5. **Reports \u0026 Alerts**\n\n   - Export irrigation/crop cycle plan as PDF\n   - Email notifications (Resend/Gmail SMTP)\n\n---\n\n## 🔹 External Innovative Features\n\n1. Offline-first PWA for low connectivity areas\n2. Geo-fencing alerts (flood, heatwave)\n3. Community benchmarking (compare yields anonymously)\n4. Open crop advisory dataset integration (FAO / ICAR)\n5. Multilingual UI (Next.js i18n)\n6. Simple ML model (train with uploaded yield history)\n7. Satellite NDVI monitoring (Sentinel free tier)\n8. Voice reports (TTS via browser / free Google TTS)\n\n---\n\n## 🔹 Feasibility to Farmers\n\n- **Free APIs** → no cost\n- **Leaflet + OSM** → no map fees\n- **Offline PWA + Email export** → works with poor connectivity\n- **Low device requirements** → runs on cheap Android phones\n\n---\n\n## 🔹 Conclusion\n\nA **monolithic Next.js app** can provide actionable crop \u0026 irrigation insights using **free weather/soil APIs + Leaflet maps**. MVP focuses on **rule-based irrigation + crop cycle models**, with optional satellite, ML, and WhatsApp/multilingual features later.\n\n---\n\n## Contributors\n\n- Sarthak Patil - Core Fullstack Programmer\n- Utkarsh Vidwat - Data and API Engineer\n- Prathamesh Kolhe - ML Engineer\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fprecise-goals%2Fsprout","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fprecise-goals%2Fsprout","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fprecise-goals%2Fsprout/lists"}
