Drivers of Phosphorus Uptake by Barley Following Secondary Resource Application
Brod, Eva; Øgaard, Anne K. Falk; Krogstad, Tore; Haraldsen, Trond; Frossard, Emmanuel; Oberson, Astrid (Artistic production; Journal article; Peer reviewed, 2016)Minable rock phosphate is a finite resource. Replacing mineral phosphorus (P) fertilizer with P-rich secondary resources is one way to manage P more efficiently, but the importance of physicochemical and microbial soil ... -
Impact of phosphorus on rhizosphere organic anions of wheat at different growth stages under field conditions
Wang, Yanliang; Krogstad, Tore; Clarke, Nicholas; Øgaard, Anne K. Falk; Clarke, Jihong (Journal article; Peer reviewed, 2017)Phosphorus (P) is one of the main limiting factors for crop productivity while rhizosphere organic anions have been hypothesized to play an important role in P acquisition. Sampling in a long-term field experiment was ... -

Øgaard, Anne K. Falk; Knutsen, Heidi; Kårstad, Signe; Fystro, Gustav; Bechmann, Marianne; Morken, John (NIBIO Rapport, Research report, 2014)Miljødirektoratets forslag til revidert forskrift for lagring og bruk av gjødsel til landbruksformål blir her utredet angående økonomiske- og praktiske konsekvenser av et utvalg av de foreslåtte bestemmelsene, samt hvilke ... -
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 ... -
Rhizosphere Organic Anions Play a Minor Role in Improving Crop Species' Ability to Take Up Residual Phosphorus (P) in Agricultural Soils Low in P Availability
Hallama, Moritz; Clarke, Nicholas; Clarke, Jihong; Eich-Greatorex, Susanne; Wang, Yanliang; Kandeler, Ellen; Krogstad, Tore; Øgaard, Anne K. Falk (Journal article; Peer reviewed, 2016)Many arable lands have accumulated large reserves of residual phosphorus (P) and a relatively large proportion of soil P is less available for uptake by plants. Root released organic anions are widely documented as a key ...
