Communities are often concerned about whether the use of biosolid fertilizers could lead to migration of bacteria and viruses away from the site of application, for instance in aerosols carried by air currents or by movement of pathogens through soil and into groundwater.
Land application of biosolids has received increased attention in the last two decades due to the ability of biosolids to replenish reduced soil organic matter, supply nutrients--mainly nitrogen (N) and phosphorus (P) and some essential micronutrients, such as zinc (Zn) and copper (Cu)--to plants, improve soil structure and water-holding capacity, and have beneficial effects on microbial biomass and activity (Eriksen et al.
