Q. What is milorganite? Can I use it as a deer repellent?
Answer
As a deer repellent, not sure, see below for help in that area.
According to Cornell: "What is Milorganite? Milorganite is sold as a fertilizer product manufactured from treated sewage sludge (also known as “biosolids”) from wastewater treatment plants from the Milwaukee Metropolitan Sewerage District. It is marketed for turf, ornamentals, shrubs, and the home garden. Sewage sludges are a semi-solid residue of organic matter generated as a byproduct of wastewater treatment. Much of the nitrogen, phosphorus and organic matter in the wastewater ends up in the sewage sludge, providing fertilizer value. However many of the contaminants and pathogens that enter the wastewater treatment plants from homes, businesses and industry also end up in the sludges".
