Table III. Trends in nutrient uptake of different root types of monocot species.

Growth Condition	Nutrient Measured	Trends for Monocot Root Type Uptake	Species/Reference
Replete nitrogen	Nitrogen	Primary > seminal > > crown	Maize/Yu et al. (2014)
Low nitrogen	Nitrogen	Primary > crown > seminal	Maize/Yu et al. (2014)
Replete sulfur	Sulfur	Primary > seminal > mesocotyl > crown	Rice/Maniou et al. (2014)
Low sulfur	Sulfur	Seminal > primary > mesocotyl > crown	Rice/Maniou et al. (2014)
Replete sulfur	Sulfate	Seminal > mesocotyl > primary > crown	Rice/Maniou et al. (2014)
Low sulfur	Sulfate	Seminal > primary > crown > mesocotyl	Rice/Maniou et al. (2014)
Aerated	Phosphorus	Seminal > crown (reversed over time)	Wheat/Wiengweera and Greenway (2004)
Stagnant	Phosphorus	Crown > seminal (all times measured)	Wheat/Wiengweera and Greenway (2004)
Aerated	Potassium	Crown > seminal (all times measured)	Wheat/Wiengweera and Greenway (2004)
Stagnant	Potassium	Crown > seminal (all times measured)	Wheat/Wiengweera and Greenway (2004)
Root type	Trends for nitrogen (N) uptake (Yu et al., 2014)
Primary	Local high N > homogenous high N > local low N > homogenous low N (60% reduction)
Seminal	Local low N > homogenous high N > local high N > homogenous low N (71% reduction)
Crown	Local high N > homogenous low N > homogenous high N > local low N (86% reduction)
