Mr. Matthew Macken:

I have been putting my money where my mouth is by using digestate at home. I ran some trials last year on some arable and grass land. Option one involved some silage ground using some chemical inputs. Option two was silage ground in the same plot with digestate only at a rate that was constituted with the outputs of the plant to match the 100 units of nitrogen required to grow a sufficient crop of silage and also some cover crop such as forage redstart and some spring barley. All of this was grown completely using organic digestate.
