Calibration of the EU-Rotate_N model with measured C and N mineralization from potential fertilizers and evaluation of its prediction of crop and soil data from a vegetable field trial
Øvsthus, Ingunn; Thorup-Kristensen, Kristian; Seljåsen, Randi; Riley, Hugh; Dörsch, Peter; Breland, Tor Arvid (Peer reviewed; Journal article, 2021-06-27)Mechanistic models are useful tools for understanding and taking account of the complex, dynamic processes such as carbon (C) and nitrogen (N) turnover in soil and crop growth. In this study, the EU-Rotate_N model was first ... -
Growth and nitrogen recovery efficiency of potato (Solanum tuberosum) fertilised with shrimp shell pellets
Johansen, Tor Jacob; Samuelsen, Tor Andreas; Øvsthus, Ingunn (Journal article; Peer reviewed, 2019-05-16)In organic plant production, nitrogen (N) availability is often a growth-limiting factor. Under such conditions, off-farm waste-derived nutrient resources may be an alternative to meet the N demand. In this study, we ... -
Yield, nitrogen recovery efficiency and quality of vegetables grown with organic waste-derived fertilisers
Øvsthus, Ingunn; Seljåsen, Randi; Stockdale, Elizabeth; Uhlig, Christian; Torp, Torfinn; Breland, Tor Arvid (Journal article; Peer reviewed, 2017-09-30)More sustainable production of high-quality, nutritious food is of worldwide interest. Increasing nutrient recycling into food systems is a step in this direction. The objective of the present study was to determine nitrogen ...
