Hey everyone! I'm Ahmed, maker of Fertilizer Dose.
We built it because guessing fertilizer amounts is expensive too much wastes money and harms the soil, too little hurts the yield. It gives exact NPK doses per acre for 31 crops plus vegetables, with planting calendars and a plant doctor. Free, no signup, 19 languages including Urdu.
Curious: what's the one crop where you always second-guess how much fertilizer to use? For me it was always tomatoes the numbers change by growth stage and region.
