I develop turnkey fertilizer dosage calculators for agricultural company and farm websites. A visitor enters plot area, selects crop and soil type, marks current plant growth stage — and the tool immediately shows recommended application rate with breakdown by nutrients: nitrogen, phosphorus, potassium, and micronutrients if needed. Behind the simple form is a customizable calculation engine: working with your agronomists, I build tables of norms by crop, soil type, and region, so calculations rely on real recommendations, not averaged figures from a handbook. The calculator recalculates when growth stage changes, supports different units of measurement, and converts the norm to a list of fertilizers accounting for concentration. Each calculator is mobile-optimized, works fast, and integrates into your website without reworking other sections. On request, I add an inquiry form: after calculation, visitors can request an agronomist consultation — turning a free tool into a source of leads. What's included: — input form for area, crop, soil type, and growth stage — customizable norm tables by region and crop — unit conversion and breakdown by nutrients — responsive design and simple website integration — inquiry form linked to calculation results
