How to use the Plant Spacing Calculator

Formula and method
Rows = width ÷ row spacing. Plants per row = length ÷ plant spacing. Total positions = rows × plants per row × usable-area fraction.
The tool applies a headland or unused-area allowance after calculating the rectangular planting grid.
Worked example
A 100 m × 50 m plot with 75 cm rows, 25 cm plant spacing and 5% allowance provides roughly 25,333 planting positions.
Understanding the result
Treat the calculated values as a planning estimate. Compare them with your field records, product information, local conditions and operational capacity before acting.
Important: Results depend on the accuracy of your inputs and the assumptions shown. Local soil, weather, crop, animal and market conditions can change the appropriate decision.
