Could you build this?
Partial The calculator UI and NPK formulas are easy to vibe-code, but the value claimed by 'verified agronomic data' for 31 crops and many regions depends on agronomic expertise and sourced recommendation tables.
What it would actually take: The stack is a simple static or lightweight web app with i18n. The hard part is building a validated crop-nutrient requirement database with regional soil and yield assumptions, which needs an agronomist or extension-service sources to review it. Without that, the numbers look plausible but can be wrong in ways that damage crops.
