This simple online tool helps growers keep track of how much food they grow, how much money they save, and how much carbon they save compared to buying produce from the supermarket. 

The Harvest-ometer stores your yield data and converts it into a money value, meal value, carbon value, and makes great graphs that you can show friends, family, supporters or even funders!

Reasons to use the harvest-ometer

  • To see how much you and your volunteers can grow.
  • To include in funding applications or on your website.
  • Because good gardeners keep records to improve yields (see Sustain Grow More Food publication).
  • To help us show policy-makers that growing food has a high value.

And finally this image shows the Harvest-ometer graph, and the option to view your harvest in terms of meals, or in terms of how much carbon the garden has saved, compared to if the same produce was bought from the supermarket. You can also show data from previous growing seasons and filter by type of produce.
