The Richmond demonstration site in southern Tasmania is located in the Coal Valley and hosted by Harvest Farms.

In 2018, a farm demonstration trial was established to examine the costs and benefits of quality compost as an organic soil amendment on spinach babyleaf crop yield and quality. This update summarises the soil pathogen DNA results from 2020, or year 3 of the trial.

A full summary of year 3, including other data such as soil microbial tests, soil moisture holding capacity and conventional soil test results, is available here.
