Sewage sludge, which may or may not be the same thing, was widely used in
forestry so there should be some data hopefully on line at Forest Research. I
have used it as pit fill when employed as a young man and remember 2 things,
the smell which was like plastercine, and the heat, which was welcome in the
bitterly cold.

Subject: Biodisc effluent - impact to trees?
Hi All,
Has anyone had experience with assessing the impact of discharging biodisc
effluent (treated sewage) into the rooting zone of trees?
The treated effluent will contain 10mg/L suspended solids and 3.8mg/L
ammonia, and will have a BOD of 10mg/L. The output could be between 1-2 cubic
metres per day.
The treatment facility is at the top of a steep bank and the trees are below
it.
I know the proposal will impact the moisture content and chemical composition
of the soil, which could impact the mycorrhizal associations and soil fauna,
but will it have a significant detrimental impact on the trees?
Regards,
