Maize and soybean root front velocity and maximum depth in Iowa, USA (2018, background): “Indeed, deep, rapid-growth root systems may reduce losses of highly soluble nutrients such as nitrate (Lynch, 2013) because RFV closely matches the rate of nitrate leaching (York and Lynch, 2015).”
Utility of root cortical aerenchyma under water limited conditions in tropical maize (Zea mays L.) (2015, background): “This is analogous to water capture under drought 326 in the sense that in both cases the limiting soil resource is primarily available in deeper soil strata 327 (Lynch 2013).”
Root traits contributing to plant productivity under drought (2013, background): “…root length density (RLD, root length per soil volume) in shallow soil layers and increased RLD in medium and deep layers has been proposed as an efficient growth strategy in environments where deep water could be available to crops later in the growing season (Wasson et al., 2012; Lynch, 2013).”
Nitrogen placement at sowing affects root growth, grain yield formation, N use efficiency in maize (2020, background): “The ‘steep, cheap, and deep’ (SCD) root ideotype for improved N capture in maize consists of architectural, anatomical, and physiological traits that promote rapid exploration of deep soil domains to capture nitrate as it leaches through the root zone (Lynch 2013).”
Root to shoot and carbon to nitrogen ratios of maize and soybean crops in the US Midwest (2020, background): “Knowledge of root length is important because it is often considered to be directly related to the acquisition of water and nutrients (Hamblin and Tennant, 1987; Van Noordwijk and De Willigen, 1991; Lynch, 2013).”
Root anatomy and soil resource capture (2021, background): “Coupling large cortical cells with fewer cortical cell files has been suggested as a synergistic combination to facilitate deeper rooting (Lynch 2013), but may have an antagonistic effect on root penetration of hard soil.”
