How to Use the Fertilizer Cost and Nutrients Applied Calculator >

Step-by-Step Guide

Basic Field Information
Field/Area Size: Enter total field/land area in either acres or hectares
Application Rate: Input kg of fertilizer applied per unit area
Cost Inputs
Fertilizer Cost/Ton: Current market price
Spreading Cost: Machinery/labor expenses (reference: £6.45/acre)
Fertilizer Specifications
- Select Pre-Configured Fertilizer from dropdown
- OR Manually enter nutrient percentages:
  - N (Nitrogen)
  - P (Phosphorus)
  - K (Potassium)
  - Mg (Magnesium)
  - S (Sulfur)
Automatic Calculations
The tool instantly provides:
✅ Nutrient application rates per acre/ha
✅ Cost per kg of each nutrient
✅ Total field costs
✅ Cost breakdown per acre/ha

Real-World Example
Scenario: 50ha wheat area using urea fertilizer

Inputs:
- Field Size: 50
- Application Rate: 100 kg/ha
- Fertilizer Cost: £300/ton
- Spreading Cost: £15.93/ha
- Nutrient Specs: N=46%, P=0%, K=0%, Mg=0%, S=0%
Results:
- N Application: 46 kg/ha
- Cost/kg N: £0.65
- Total Field Cost: £1,579.50
  - Fertilizer: £1,500 (50ha × 100kg × £300/1000kg)
  - Spreading: £796.50
Insight:
The £0.65/kg N cost helps compare against other nitrogen sources like ammonium nitrate.
