You are an advanced agricultural economist. I will provide the farmer's **Current Annual Crop Cycle**.
|
|
|
Your task is to generate a **3-Year Optimization Plan** and explicitly explain **WHY their current plan is losing money/underperforming** compared to the potential.
|
|
|
|
|
|
**Inputs:**
|
|
|
- Location: {location}
|
|
|
- Total Area: {total_area} acres
|
|
|
- Current Annual Plan: {current_plan}
|
|
|
|
|
|
**OUTPUT FORMAT INSTRUCTIONS:**
|
|
|
Generate ONLY the HTML content inside `<div>` tags. Use the specific CSS classes below.
|
|
|
|
|
|
**Structure & CSS Classes to Use:**
|
|
|
|
|
|
1. **Executive Summary (2 Cards):**
|
|
|
Use `<div class="stats-grid" style="grid-template-columns: 1fr 1fr; max-width: 700px; margin: 0 auto 1.5rem;">` containing:
|
|
|
- Card 1: **Projected Annual Net Profit** (Value in `stat-value`)
|
|
|
- Card 2: **Revenue Increase** (Value in `stat-value` with `color: #1a5d3a`)
|
|
|
|
|
|
2. **GAP ANALYSIS (Why the Loss?):**
|
|
|
Header: `<h3><i class="bi bi-search"></i> Input Strategy Analysis</h3>`
|
|
|
Use `<div class="gap-analysis-card">` (I will add this CSS):
|
|
|
- `<h4><i class="bi bi-exclamation-circle"></i> Inefficiencies Detected in Current Plan:</h4>`
|
|
|
- `<ul>`
|
|
|
- `<li><b>[Factor 1]:</b> [Explanation, e.g., 'Monoculture of Wheat increases pest risk and fertilizer cost by 20%']</li>`
|
|
|
- `<li><b>[Factor 2]:</b> [Explanation, e.g., 'Missing Zaid season leaves 4 months of revenue potential on the table']</li>`
|
|
|
- `<li><b>[Factor 3]:</b> [Explanation]</li>`
|
|
|
- `</ul>`
|
|
|
|
|
|
3. **Annual Financial Breakdown (Single Bar):**
|
|
|
Header: `<h3><i class="bi bi-pie-chart"></i> Projected Financials</h3>`
|
|
|
Use `<div class="breakdown-section">`:
|
|
|
- Title: `<div class="breakdown-title"><span>Breakdown (Avg Annual)</span> <span>Total Rev: [Value]</span></div>`
|
|
|
- Stacked Bar: `<div class="stacked-bar-container">`
|
|
|
- `<div class="bar-cost" style="width: [Cost%]%">Cost [Value]</div>`
|
|
|
- `<div class="bar-profit" style="width: [Profit%]%">Profit [Value]</div>`
|
|
|
- Legend included below.
|
|
|
|
|
|
4. **3-Year Crop Rotation (Vertical Stalk):**
|
|
|
Header: `<h3><i class="bi bi-bezier2"></i> Crop Rotation Journey</h3>`
|
|
|
Use `<div class="growth-timeline">`:
|
|
|
- **For EACH Year (1, 2, 3):**
|
|
|
`<div class="growth-node">`
|
|
|
`<div class="growth-card">`
|
|
|
`<div class="growth-header">`
|
|
|
`<span>Year 1</span>`
|
|
|
`<span>Est. Income: [Value]</span>`
|
|
|
`</div>`
|
|
|
`<table class="annual-table">`
|
|
|
`<thead><tr><th>Season</th><th>Crop</th><th>Exp/Rev/Profit</th></tr></thead>`
|
|
|
`<tbody>`
|
|
|
`<tr>`
|
|
|
`<td><span class="season-badge">Kharif</span></td>`
|
|
|
`<td><b>[Crop Name]</b></td>`
|
|
|
`<td>Exp: [Val]<br>Prof: <b>[Val]</b></td>`
|
|
|
`</tr>`
|
|
|
`<tr>`
|
|
|
`<td><span class="season-badge">Rabi</span></td>`
|
|
|
`<td><b>[Crop Name]</b></td>`
|
|
|
`<td>Exp: [Val]<br>Prof: <b>[Val]</b></td>`
|
|
|
`</tr>`
|
|
|
`<tr>`
|
|
|
`<td><span class="season-badge">Zaid</span></td>`
|
|
|
`<td><b>[Crop Name]</b></td>`
|
|
|
`<td>Exp: [Val]<br>Prof: <b>[Val]</b></td>`
|
|
|
`</tr>`
|
|
|
`</tbody>`
|
|
|
`</table>`
|
|
|
`</div>`
|
|
|
`</div>`
|
|
|
|
|
|
5. **Comparison Table:**
|
|
|
Header: `<h3><i class="bi bi-table"></i> Strategy Comparison</h3>`
|
|
|
Use `<div class="smart-table-container">` with `<table class="smart-table">`.
|
|
|
- Columns: Metric, Current Annual Plan, Proposed (Avg Annual), Change.
|
|
|
- Rows: Gross Revenue, Total Cost, Net Profit.
|
|
|
- **COLOR LOGIC:**
|
|
|
- **Total Cost:** Identify if Cost Increases or Decreases. Mark "Cost Increase" as `<span class="negative">` (Red). Mark "Cost Decrease" as `<span class="positive">` (Green).
|
|
|
- **Net Profit:** Increase = Positive (Green).
|
|
|
|
|
|
**Guidelines:**
|
|
|
- **Language:** {language}
|
|
|
- **REALISM:** Ensure the gap isn't exaggerated. If the current plan is decent, say so. If it's bad, explain EXACTLY why (e.g., pests, soil depletion, unused seasons).
