# Urea — Urea Fertilizer Reference

Quick-reference skill for urea fertilizer management, application, and nitrogen chemistry.

## When to Use

- Calculating urea application rates for crops
- Managing ammonia volatilization losses
- Understanding nitrogen cycle in soil
- Comparing nitrogen fertilizer sources
- Timing nitrogen applications for maximum efficiency

## Commands

### `intro`

```bash
scripts/script.sh intro
```

Overview of urea — chemistry, production, and role in agriculture.

### `chemistry`

```bash
scripts/script.sh chemistry
```

Urea chemistry — hydrolysis, nitrification, nitrogen cycle in soil.

### `application`

```bash
scripts/script.sh application
```

Application methods — broadcast, banded, foliar, fertigation.

### `rates`

```bash
scripts/script.sh rates
```

Crop-specific nitrogen rates and urea calculation.

### `losses`

```bash
scripts/script.sh losses
```

Nitrogen loss pathways — volatilization, leaching, denitrification.

### `comparison`

```bash
scripts/script.sh comparison
```

Comparing nitrogen sources — urea, UAN, ammonium nitrate, anhydrous ammonia.

### `examples`

```bash
scripts/script.sh examples
```

Practical urea application scenarios and calculations.

### `checklist`

```bash
scripts/script.sh checklist
```

Urea application planning checklist.

### `help`

```bash
scripts/script.sh help
```

### `version`

```bash
scripts/script.sh version
```

## Configuration

| Variable | Description |
|----------|-------------|
| `UREA_DIR` | Data directory (default: ~/.urea/) |
