The formula
harvest = average sample weight ÷ sample area × field area × (1 − loss)
The lightest and heaviest samples are scaled the same way to give a rough range.
What to watch out for
This suits grain, roots, vegetables and fruit, or anything you can weigh from a measured area. Take samples at random rather than the best-looking spots. Use a separate estimate for clearly different parts of a field.
Frequently Asked Questions
How many samples do I need?
At least four, spread across the field. If they disagree widely, take more and enter an average for each part of the field.
What does an average of 0.78 kg/m² come to?
7.8 t/ha, or 78 t on 10 ha before losses.
