Root growth and nitrogen uptake of carrot, early cabbage, onion and lettuce following a range of green manures (2006, background): “This difference in N uptake can be used as an estimate of N fixation (Mueller & Thorup-Kristensen, 2001).”
Root characteristics of selected field crops: Data from the Wageningen Rhizolab (1990–2002) (2005, background): “Thorup Kristensen (2001) reported that monocot species had rooting depth penetration rates in the range of 0.10–0.12 cm ( C day))1 whereas non-legume dicots had rates between 0.15 and 0.23 cm ( C day))1.”
Influence of root and leaf traits on the uptake of nutrients in cover crops (2016, background): “Influence of plant traits on nutrient uptake Numerous studies have been conducted on the shoots of the cover crops (e.g. Brennan and Boyd 2012; RamirezGarcia et al. 2014) but only few investigated their root system despite its importance (e.g. Thorup-Kristensen 2001; Bodner et al. 2013, 2014).”
Modelling diverse root density dynamics and deep nitrogen uptake—A simple approach (2009, background): “…distribution does not comply accurately with the root distribution measured in the field (Figure 10), but it has previously been shown that rooting depth may be more important than root density distribution for determining the ability of crops to deplete soil inorganic N (Thorup-Kristensen, 2001).”
Improved evaluation of cover crop species by growth and root factors (2010, background): “Cover crop rooting traits contribute essentially to their agro-environmental functions (e.g. Thorup-Kristensen, 2001).”
Effect of winter cover crop species and planting methods on maize yield and N availability under irrigated Mediterranean conditions (2011, background): “Deeper soil N depletions were expected for the Brassica species, as previously reported (Thorup-Kristensen, 2001).”
Root biomass in cereals, catch crops and weeds can be reliably estimated without considering aboveground biomass (2018, methodology): “Chirinda et al. (2012) used the method for cereal crops also to measure catch crops in early November.”
Effect of deep and shallow root systems on the dynamics of soil inorganic N during 3-year crop rotations (2006, background): “soil N depletion ( Thorup-Kristensen 2001 ) and it is much faster to record.”
