Lately I have been reading that worm juice may improve plant growth;
The worm juice could be improving growth by adding nutrients to the soil or maybe reducing diseases.
I would like to investigate whether worm juice has an effect on stopping disease growth on root vegetables,
What I would like to find is whether worm juice helps plants grow better by having an impact on soil disease.
I think potatoes would be a good plant to test as I have found that there are lots of soil borne diseases that can affect potato plants.
