Description: This PR introduces the "L3-Tier" Soil Nutrient Optimization engine, expanding existing fertigation capabilities to include autonomous micronutrient balancing and dynamic weather-corrected injection strategies. It also resolves critical placeholders in the legacy
FertigationService
.
Key Enhancements:
Micronutrient Profiling: Added
FieldMicronutrients
model to track trace minerals (Zinc, Iron, Boron, Manganese, Copper) and Microbial Activity Indices.
Autonomous N-P-K-S Balancing: Implemented the
NutrientAdvisor
service, which calculates optimal N-P-1K-S ratios based on specific crop growth stages (Vegetative, Flowering, Ripening) and real-time soil nutrient flux.
Dynamic Weather/Leaching Core: Fixed the static weather location bug in
FertigationService
. The system now fetches micro-climate data specific to each zone, adjusting chemical concentrations based on 24h rainfall projections to prevent environmental runoff.
Area-Based Volume Precision: Fixed hardcoded volume logging. The engine now calculates precise carrier water requirements based on zone acreage and current moisture deficit.
Financial Integrity: Integrated the NUTRIENT_REBALANCE_COST transaction type into the double-entry ledger for automated billing of specialized micronutrient injections.
Continuous Optimization: Registered a new Celery task, nutrient_optimization_sweep, to periodically recalibrate and apply soil-health optimizations across all enabled irrigation zones.
