## Key Statistics

### Temporal Coverage
- **Years**: 2014-2024 (missing 2017 due to data format issues)
- **Seasons**: All agricultural seasons represented
- **Frequency**: Multiple interventions per plot per year

### Spatial Coverage
- **Plots**: 100 unique agricultural parcels
- **Surface**: Variable plot sizes (0.43 to 5+ hectares)
- **Location**: Single experimental station (controlled conditions)

### Intervention Types
- **Herbicide applications**: 800+ treatments
- **Total interventions**: 4,663 records
- **Product families**: Herbicides, Fungicides, Insecticides, Fertilizers
- **Most common crops**: Wheat, Corn, Rapeseed

## Treatment Frequency Index (IFT)

### Definition
The IFT (Indice de Fréquence de Traitement) is a key metric calculated as:
```
IFT = Number of applications / Plot surface area
```

### Interpretation
- **IFT < 1.0**: Low weed pressure (suitable for sensitive crops)
- **IFT 1.0-2.0**: Moderate pressure (monitoring required)
- **IFT > 2.0**: High pressure (intervention needed)

### Dataset Statistics
- **Mean IFT**: 1.93 (moderate pressure)
- **Range**: 0.14 - 6.67
- **Trend**: Decreasing from 2.91 (2014) to 1.74 (2024)

## Data Quality

### Completeness
- **Core fields**: 95%+ completeness for essential variables
- **Date fields**: Well-formatted and consistent
- **Numeric fields**: Validated ranges and units
- **Geographic data**: Anonymized but consistent plot identifiers

### Validation
- **Cross-references**: Product codes validated against official databases
- **Temporal consistency**: Logical intervention sequences
- **Agronomic validity**: Realistic crop rotations and treatment patterns

### Limitations
- **Geographic scope**: Single experimental station (limited geographic diversity)
- **Weather data**: Not included (external source required)
- **Economic data**: Treatment costs not provided
- **Soil characteristics**: Limited soil type information

## Ethical Considerations

### Privacy Protection
- **Location data**: Generalized to protect farm location
- **Personal information**: All farmer identifying data removed
- **Commercial sensitivity**: Product usage patterns aggregated when appropriate

### Bias Considerations
- **Geographic bias**: Limited to Brittany region
- **Temporal bias**: Recent years may have different practices
- **Selection bias**: Experimental station may not represent typical farms
- **Technology bias**: Practices may reflect research station capabilities

## Applications

### 1. Weed Pressure Prediction
Use machine learning models to predict future IFT values based on:
- Historical treatment patterns
- Crop rotation sequences
- Environmental factors
- Plot characteristics

**Example Model Performance**:
- Random Forest Regressor: R² = 0.65-0.85
- Features: Year, plot surface, previous IFT, crop type, rotation sequence

### 2. Sustainable Plot Selection
Identify plots suitable for sensitive crops (peas, beans) by:
- Analyzing historical IFT trends
- Evaluating rotation impacts
- Assessing risk levels for future years

### 3. Crop Rotation Optimization
Optimize rotation sequences through:
- Impact analysis of different crop sequences
- Identification of beneficial rotations
- Risk assessment for specific transitions

**Best Rotations (Lowest IFT)**:
1. Peas → Rapeseed: IFT 0.62
2. Winter Barley → Rapeseed: IFT 0.64
3. Corn → Spring Barley: IFT 0.69

### 4. Herbicide Alternative Analysis
Support reduction strategies through:
- Product usage pattern analysis
- Temporal trend identification
- Alternative strategy development

## Code Examples

### Loading the Dataset
```python
from datasets import load_dataset

# Load the dataset
dataset = load_dataset("HackathonCRA/2024")

# Convert to pandas for analysis
import pandas as pd
df = dataset["train"].to_pandas()

print(f"Loaded {len(df)} intervention records")
print(f"Covering {df['year'].nunique()} years")
```

### Calculate IFT
```python
# Calculate IFT for herbicide applications
herbicides = df[df['familleprod'].str.contains('Herbicides', na=False)]

ift_data = herbicides.groupby(['plot_name', 'year', 'crop_type']).agg({
    'quantitetot': 'sum',
    'produit': 'count',  # Number of applications
    'surfparc': 'first'
}).reset_index()

ift_data['ift'] = ift_data['produit'] / ift_data['surfparc']
```

### Analyze Crop Rotations
```python
# Create rotation sequences
rotations = []
for plot in df['plot_name'].unique():
    plot_data = df[df['plot_name'] == plot].sort_values('year')
    crops = plot_data.groupby('year')['crop_type'].first()
    
    for i in range(len(crops)-1):
        rotation = f"{crops.iloc[i]} → {crops.iloc[i+1]}"
        rotations.append({
            'plot': plot,
            'year_from': crops.index[i],
            'year_to': crops.index[i+1],
            'rotation': rotation
        })

rotation_df = pd.DataFrame(rotations)
```
