A multi-regional soil phosphorus balance for exploring secondary fertilizer potential: the case of Norway
Hanserud, Ola Stedje; Brod, Eva; Øgaard, Anne K. Falk; Müller, Daniel Beat; Brattebø, Helge (Journal article; Peer reviewed, 2015)Phosphate rock is a non-renewable source of phosphorus (P) in mineral fertilizer and many countries need to use P fertilizer more efficiently in food production. This study explored the theoretical fertilizer potential of ... -
Phosphorus Management in an Environmental Systems Perspective: The role of secondary phosphorus recycling in the case of Norway
Hanserud, Ola Stedje (Doctoral theses at NTNU;2018:70, Doctoral thesis, 2018)Abstract Crop production depends on fertilizer inputs, including phosphorus (P), to maintain soil fertility over time. The P source of mineral fertilizers is mined phosphate rock, a non-renewable resource that has been ... -
Redistributing Phosphorus in Animal Manure from a Livestock-Intensive Region to an Arable Region: Exploration of Environmental Consequences
Hanserud, Ola Stedje; Lyng, Kari-Anne; de Vries, Jerke W.; Øgaard, Anne K. Falk; Brattebø, Helge (Journal article; Peer reviewed, 2017)Specialized agricultural production between regions has led to large regional differences in soil phosphorus (P) over time. Redistribution of surplus manure P from high livestock density regions to regions with arable ... -
Regional Substance Flow Analysis for Assessment of Long-term Phosphorus Accumulation in Soil
Zabrodina, Marina Vladimirovna (Master thesis, 2013)Phosphorus is a non-renewable resource that is essential for food production. At the same time, phosphorus may cause environmental problems because excess phosphorus in agricultural soil often leads to eutrophication. For ...
