Abstract Root phenotyping describes methods for measuring root properties, or traits. While can be challenging, it is advancing quickly. In order the field to move forward, essential understand current state and challenges of phenotyping, as well pressing needs biology community. this letter, we present discuss results a survey that was created disseminated by members Graduate Student Postdoc Ambassador Program at 11th symposium International Society Research. This aimed (1) provide an...
Conservation agriculture (CA) has been reported to affect nutrient cycling. This study aims investigate how CA induced soil organic matter stratification affects carbon and nitrogen turnover. A case farm was established on two Danish farms with conventional ploughed tillage (P) practises. Here, we studied patterns 50 cm depth differed between the systems. Further investigated differences in mineralization lab incubation experiments. Average ratio, ratio C N content upper 5 at 20–30 cm, of...
No-till and mulching are typical management operations in conservation agriculture (CA). To model pesticide degradation leaching under a CA scenario, as compared to conventional-tillage scenario (CT), the mulch module of agro-hydrological Daisy was extended. A soil column parameterized with measurements topsoil, mulch, realistic subsoil, tested against published experimental data fate laboratory columns covered by mulch. Uncertainty sensitivity analyses new version were conducted for series...
Deep rooting winter wheat genotypes can reduce nitrate leaching losses and increase N uptake. We aimed to investigate which deep root traits are correlated uptake estimate genetic variation in 15 tracer In 2 years, were grown RadiMax, a semifield root-screening facility. Minirhizotron imaging was performed three times during the main growing season. At anthesis, injected via subsurface drip irrigation at 1.8 m depth. Mature ears from above injection area analysed for content. From...
Abstract The number of studies investigating root length has increased, particularly in the context measurements observed through windows such as minirhizotrons and rhizoboxes. However, there are currently two obstacles constraining their broader utility: (1) absence standardized terminology or units for data, (2) translation from two-dimensional (2D) to three-dimensional (3D) data. Here, we delineate fundamental disparities between obtained observation via volumetric soil sampling propose...
Abstract Background and aims Root distribution over the soil profile is important for crop resource uptake. Using machine learning (ML), this study investigated whether measured square root of planar length density (Sqrt_pRLD) at different depths were related to uptake isotope tracer (15N) drought stress indicator (13C) in wheat, reveal function. Methods In RadiMax semi-field root-screening facility 95 winter wheat genotypes phenotyped growth 2018 120 2019. minirhizotron technique, images...
