AgroMatrix β€” "Digital Advisor" for Agronomists.

  • Concept: A geospatial analysis system for crop rotation planning using ML-based risk assessment.
  • Smart Analytics: Unlike standard digital logs, it recommends crops based on soil chemistry, economics, and weather risks.
  • Tech Stack: Java 17+ & Spring Boot for the "Brain", Python (Scikit-learn) for ML-scoring, and Leaflet for interactive field mapping.
  • Key Feature: Predictive models for drought/disease risks and price trend forecasting using ARIMA/Prophet.
