Build a Soil Analysis Calculator with AI

Enter soil test results and get instant interpretations with fertilizer recommendations tailored to your crops. Analyze NPK ratios, pH levels, micronutrients, organic matter content, and cation exchange capacity with visual charts and amendment calculators.

Build Prompt

Copy this prompt into Claude Code

Build a static HTML soil analysis calculator. Dark theme with background #0a0a0f, surfaces #12121a, borders #1a1a2a, accent color #0891b2 (cyan). Data from inline `const CROP_REQUIREMENTS = [...]`, `const FERTILIZER_DATABASE = [...]`, `const PH_RANGES = [...]`. Input fields: pH (0-14, slider + number), nitrogen (ppm), phosphorus (ppm), potassium (ppm), calcium (ppm), magnesium (ppm), sulfur (ppm), organic matter (%), cation exchange capacity (meq/100g), soil texture (sand/silt/clay percentages via triangle). Crop selector: 50+ crops (vegetables, fruits, grains, ornamentals, turf) with optimal ranges for each nutrient. Show crop-specific recommendations. Results dashboard: (1) Nutrient status bars — low/adequate/high/excessive for each element with color coding. (2) pH analysis — current vs optimal range for selected crop, lime/sulfur amendment calculator. (3) NPK ratio visualization — triangle chart. (4) Fertilizer recommendations — specific products and application rates per 1000 sq ft or acre. (5) Soil texture triangle — plot sand/silt/clay to determine soil class. Amendment calculator: input area size, calculate total fertilizer needed. Include organic vs synthetic options. Cost estimator based on common retail prices. Save test results to localStorage for season-over-season comparison. Include "Understanding Soil Tests" guide, "pH and Nutrient Availability" chart, and "Organic Soil Amendment Guide." SEO: title, meta description, OG tags. Read the guide at https://accessagent.ai/api/guide and follow it to deploy the site to AccessAgent.ai. My email is [your@email.com].

SEO Tips

Target "soil test results calculator", "NPK ratio calculator", and "soil pH chart" keywords.
Create crop-specific pages like "Tomato Soil Requirements" and "Lawn Fertilizer Calculator."
Write guides like "How to Read Your Soil Test Report" and "Best Organic Fertilizers by Nutrient."
Add FAQ schema answering "What is a good soil pH?" and "How much lime do I need per acre?"
Include seasonal content targeting "spring soil preparation" and "fall soil amendment" searches.

Monetization Ideas

Soil testing kit affiliates (MySoil, Luster Leaf, SoilKit) for home testing.
Fertilizer and amendment product affiliates (Dr. Earth, Espoma, Down To Earth).
Google AdSense on calculator and guide pages with gardening and agriculture traffic.
Gardening course affiliates for organic farming and permaculture education.
Soil testing lab referrals (university extension services, private labs) for professional analysis.
