How This Calculator Works

This tool helps Zambian farmers estimate the exact amount of fertilizer required for their crops based on farm size and recommended application rates.

Fertilizer is one of the most important inputs in agriculture — it improves soil fertility, increases crop yield, and supports healthy plant growth. Proper calculation helps reduce waste and unnecessary cost.

Enter your crop type, farm size in hectares, fertilizer application rate (kg per hectare), bag size, and price per bag in Zambian Kwacha (ZMW). The calculator returns total fertilizer in kg, bags required, and total estimated cost.
