The effects of soil compaction on wheat seedling root growth are specific to soil texture and soil moisture status (2023)
Journal Article

Soil structure is a crucial soil physical property that determines a soil's ability to support the growth and development of plants. Soil compaction modifies soil structure by reducing pore space between soil particles thereby leading to a denser soi...

Soil structure has a greater effect on the rooting of wheat (Triticum aestivum L.) than nitrogen fertilisation rate or genotype (2023)
Journal Article

Despite extensive research over the last century concerning the application of nitrogen fertilizer to support the production of wheat (Triticum aestivum L.), our understanding on how this impacts on root growth in subsoils is limited. In this study,... Read More about Soil structure has a greater effect on the rooting of wheat (Triticum aestivum L.) than nitrogen fertilisation rate or genotype.

Root angle is controlled by EGT1in cereal crops employing anantigravitropic mechanism (2022)
Journal Article

Root angle in crops represents a key trait for efficient capture of soil resources. Root angle is determined by competing gravitropic versus anti-gravitropic offset (AGO) mechanisms. Here we report a new root angle regulatory gene termed ENHANCED GRA... Read More about Root angle is controlled by EGT1in cereal crops employing anantigravitropic mechanism.

Ethylene inhibits rice root elongation in compacted soil via ABA- and auxin-mediated mechanisms (2022)
Journal Article

Soil compaction represents a major agronomic challenge, inhibiting root elongation and impacting crop yields. Roots use ethylene to sense soil compaction as the restricted air space causes this gaseous signal to accumulate around root tips. Ethylene...

X-ray CT reveals 4D root system development and lateral root responses to nitrate in soil (2022)
Journal Article

The spatial arrangement of the root system, termed root system architecture, is important for resource acquisition as it directly affects the soil zone explored. Methods for phenotyping roots are mostly destructive, which prevents analysis of roots o... Read More about X-ray CT reveals 4D root system development and lateral root responses to nitrate in soil.

Future roots for future soils (2021)
Journal Article

Mechanical impedance constrains root growth in most soils. Crop cultivation changed the impedance characteristics of native soils, through topsoil erosion, loss of organic matter, disruption of soil structure and loss of biopores. Increasing adoption...

Shifts in Soil Structure, Biological, and Functional Diversity Under Long-Term Carbon Deprivation (2021)
Journal Article

Soil organic matter is composed of a variety of carbon (C) forms. However, not all forms are equally accessible to soil microorganisms. Deprivation of C inputs will cause changes in the physical and microbial community structures of soils; yet the tr...

Microbial Metal Resistance within Structured Environments Is Inversely Related to Environmental Pore Size (2021)
Journal Article

The physical environments in which microorganisms naturally reside rarely have homogeneous structure, and changes in their porous architecture may have effects on microbial activities that are not typically captured in conventional laboratory studies...

Plant roots sense soil compaction through restricted ethylene diffusion (2021)
Journal Article

© 2021 The Authors, some rights reserved. Soil compaction represents a major challenge for modern agriculture. Compaction is intuitively thought to reduce root growth by limiting the ability of roots to penetrate harder soils. We report that root gro...

Soil aggregates by design: Manufactured aggregates with defined microbial composition for interrogating microbial activities in soil microhabitats (2020)
Journal Article

Differences in the structure of microbial communities are reported to exist between the inside and outside of soil aggregates, but the impacts of soil aggregation on microbial activity in soils, essential for soil health, have proven difficult to stu...

A comparison between water uptake and root length density in winter wheat: effects of root density and rhizosphere properties (2020)
Journal Article

© 2020, The Author(s). Background and aims: We aim to quantify the variation in root distribution in a set of 35 experimental wheat lines. We also compared the effect of variation in hydraulic properties of the rhizosphere on water uptake by roots. M...

Ecosystem services for intensification of agriculture, with emphasis on increased nitrogen ecological use efficiency (2020)
Journal Article

© 2020 The Authors. In weathered tropical soil, low nutrient use efficiency can lead to agricultural systems becoming unsustainable. Therefore, tropical agriculture is highly dependent on ecosystem services, such as nutrient recycling and carbon sequ...

Soil strength influences wheat root interactions with soil macropores (2019)
Journal Article

Deep rooting is critical for access to water and nutrients found in subsoil. However, damage to soil structure and the natural increase in soil strength with depth, often impedes root penetration. Evidence suggests that roots use macropores (soil cav... Read More about Soil strength influences wheat root interactions with soil macropores.

Multiple abiotic stress, nitrate availability and the growth of wheat (2019)
Journal Article

In the field, wheat experiences a combination of physical and nutrient stresses. There has been a tendency to study root impedance and water stress in separation and less is known about how they might interact. In this study, we investigated the effe...

Interaction between contrasting rice genotypes and soil physical conditions induced by hydraulic stresses typical of alternate wetting and drying irrigation of soil (2018)
Journal Article

© 2018, The Author(s). Background and aims: Alternate wetting and drying (AWD) saves water in paddy rice production but could influence soil physical conditions and root growth.

Assessing water uptake in sugar beet (Beta vulgaris) under different watering regimes (2017)
Journal Article

Sugar beet yield worldwide is substantially reduced as a result of drought stress. Water uptake may be limited by the plant (e.g. low root density) or by soil physical constraints.
