TLDR
Results support the hypothesis that root growth angles are primary determinants of N acquisition in maize, and suggest that genetic selection for root phenotypes could be tailored to specific environments.About:

Root phenotypes for improved nutrient capture: an underexploited opportunity for global agriculture.
TL;DR: Although the current understanding is sufficient to deploy root phenotypes for improved nutrient capture in crop breeding, this complex topic does not receive the resources it merits in either applied or basic plant biology.

TL;DR: A major aim of this guide is to help break down barriers between the many subdisciplines of root ecology and ecophysiology, broaden researchers’ views on the multiple aspects of root study and create favourable conditions for the inception of comprehensive experiments on the role of roots in plant and ecosystem functioning.

TL;DR: This work presents candidate G2P models for the integration of genomic and new phenotyping information and illustrates their use in examples with special attention to the modelling of genotype by environment interactions.

TL;DR: 3D root architecture is shaped by myriad environmental signals to ensure resource capture is optimised and unfavourable environments are avoided, resulting in a 'custom-made' 3D root system that is best adapted to forage for resources in each soil environment that a plant colonises.

A closed-form equation for predicting the hydraulic conductivity of unsaturated soils
van Genuchten,M. Th. +1 more
TL;DR: Van Genuchten et al. as mentioned in this paper proposed a closed-form analytical expression for predicting the hydraulic conductivity of unsaturated soils based on the Mualem theory, which can be used to predict the unsaturated hydraulic flow and mass transport in unsaturated zone.

Capillary conduction of liquids through porous mediums
TL;DR: In this article, the authors used Darcey's law to derive the equation K∇2ψ+∇K·∇ψ +g∂K/∂z=−ρsA∆ψ/∆t for the capillary conduction of liquids in porous mediums.
Journal ArticleDOI
rosetta: a computer program for estimating soil hydraulic parameters with hierarchical pedotransfer functions
TL;DR: In this paper, the authors describe a computer program, rosetta, which implements five hierarchical pedotransfer functions (PTFs) for the estimation of water retention, and the saturated and unsaturated hydraulic conductivity.

Agroecosystems, Nitrogen-use Efficiency, and Nitrogen Management
TL;DR: The global challenge of meeting increased food demand and protecting environmental quality will be won or lost in cropping systems that produce maize, rice, and wheat as discussed by the authors, and the research agenda and developing effective policies to meet this challenge requires quantitative understanding of current levels of N-use efficiency and losses in these systems, the biophysical controls on these factors, and the economic returns from adoption of improved management practices.
