To understand the impacts of surface application of effluent on soil health and opportunities for soil carbon sequestration.
The project undertook a review of current literature on the impacts of piggery effluent on soil health, considering both positive and negative effects. It also undertook a survey of producers to understand current practices as well as detailed soil testing on paddocks sprayed and not sprayed with effluent to document any effects.
The project found that currently the benefits outweigh the risks of using effluent. Further research into the long-term impacts are needed and how this might change if more producers take up a waste to energy (biogas) system.
