Journal ArticleDOI
Root elongation, water stress, and mechanical impedance: a review of limiting stresses and beneficial root tip traits
TL;DR: A survey of 19 soils, with textures ranging from loamy sand to silty clay loam, found that mechanical impedance is often a major limitation to root elongation in these soils even under moderately wet conditions, and is important to consider in breeding programmes for drought-resistant crops.
Journal ArticleDOI
Improving intercropping: a synthesis of research in agronomy, plant physiology and ecology.
Rob W. Brooker,Alison E. Bennett,Wen-Feng Cong,Tim J. Daniell,Timothy S. George,Paul D. Hallett,Paul D. Hallett,Cathy Hawes,Pietro P. M. Iannetta,Hamlyn G. Jones,Hamlyn G. Jones,Alison J. Karley,Long Li,Blair M. McKenzie,Robin J. Pakeman,Eric Paterson,Christian Schöb,Jianbo Shen,Geoff R. Squire,Christine A. Watson,Chaochun Zhang,Fusuo Zhang,Junling Zhang,Philip J. White +23 more
TL;DR: It is suggested that other topics also need addressing, including better assessment of the wider benefits of intercropping in terms of multiple ecosystem services, collaboration with agricultural engineering, and more effective interdisciplinary research.
Journal ArticleDOI
Grazing effects on soil physical properties and the consequences for pastures: a review
TL;DR: In this article, the effects of grazing on soil physical properties and the consequent effects of these properties on pasture growth and composition are discussed. But, the authors do not consider the effect of pasture to the poorer soil conditions caused by grazing, but it is likely to be small compared with the defoliation effects.
Journal ArticleDOI
Liming impacts on soils, crops and biodiversity in the UK: A review.
Jonathan Holland,Alison E. Bennett,Adrian C. Newton,Philip J. White,Blair M. McKenzie,Timothy S. George,Robin J. Pakeman,J.S. Bailey,Dario A. Fornara,Richard Hayes +9 more
TL;DR: Understanding ofLiming impacts on soil and crop processes are explored together with functional aspects (in terms of ecosystems services) in a new qualitative framework that includes consideration of how liming impacts change with time.
Journal ArticleDOI
Matching roots to their environment
Philip J. White,Timothy S. George,Peter J. Gregory,Peter J. Gregory,A. Glyn Bengough,A. Glyn Bengough,Paul D. Hallett,Blair M. McKenzie +7 more
TL;DR: How land plants and their roots evolved is examined, how the ecology of roots and their rhizospheres contributes to the acquisition of soil resources is described, and the influence of plant roots on biogeochemical cycles are discussed.
