Building Fertilizer Dose, a free NPK fertilizer calculator for farmers and gardeners. Verified agronomic data, 31 crops, 19 languages.
Hey Product Hunt! I'm Ahmed, the maker of Fertilizer Dose.
Here's the problem I kept running into: fertilizer advice online is either vague ("just apply a handful") or a single unexplained number. Farmers guess, waste money and over fertilizing washes straight into waterways.
Fertilizer Dose ends the guessing. Pick your crop from 31 field crops, 17 vegetables and 8 plants and get the exact recommended NPK dose for your land, per acre, kanal, marla or hectare with every calculation shown step by step and sourced from published agronomic recommendations. Data that isn't verified yet is marked "in review" never invented.
There's also a region-aware planting calendar, a Plant Doctor for sick plants, a Deficiency Checker, Soil Test Calculator and a Kitchen Garden Planner. Free forever no sign-up 19 languages.
I'd genuinely love your feedback: which crops or regions should we verify next?
