Frequently Asked Questions

To calculate total fertilizer, multiply your land area (in hectares) by the recommended application rate (in kg/ha). For example, if you have 2 hectares and the rate is 150 kg/ha, you need 300 kg of fertilizer.
Application rates vary significantly based on crop type, soil quality, and the specific fertilizer's nutrient content. Always refer to soil test results or agricultural guidelines for your specific region and crop.
Yes! If your liquid fertilizer application rate is provided in kilograms or liters per hectare, the calculation logic (Area × Rate) remains the same for volume or weight estimation.
Accurate calculation prevents over-application (which can harm the environment and waste money) and under-application (which results in poor crop yields).
This tool calculates the total weight of the fertilizer product. To calculate specific nutrients (Nitrogen, Phosphorus, Potassium), you'll first need to know the percentage of each in your fertilizer mix.
