NPK 19-19-19: ₹50-80/kg। Urea: ₹5-10/kg (subsidized!)। Vermicompost: ₹8-15/kg। 1000 sq ft: 2-3 kg NPK per application। 3-4 applications/year। Monsoon: heavy fertilizing (growth period)। Winter: light। Cow dung manure: free in rural India — best organic option।

Organic

Vermicompost + neem cake: complete organic solution। Neem cake: pest control + fertilizer। ₹20-40/kg।

⚡ CalcWolf Insight

The single most impactful lawn fertilizer application is the late fall "winterizer" — applied after the last mowing when the grass has stopped growing but before the ground freezes. This feeding builds root reserves that fuel a strong spring green-up without early spring fertilizer.
