Pulp mill sludges as a solution for reducing the risk of mineral nitrogen leaching from agriculture Open
Nitrogen (N) from agricultural systems contributes to the eutrophication of waterbodies through leaching. Incorporating organic material with a high carbon-to-nitrogen (C/N) ratio, such as mixed pulp mill sludges (PMSs), into the soil in a…

Effects of mixed pulp mill sludges on crop yields and quality Open
There is a great need for sustainable fertilisers and soil amendments, as current fertilisation practices negativelyaffect the environment. Pulp mill sludges (PMS) could provide a means to replace fertilisers made using non-renewable resou…
