Application of microfluidic systems in modelling impacts of environmental structure on stress-sensing by individual microbial cells (2021)
Journal Article

Environmental structure describes physical structure that can determine heterogenous spatial distribution of biotic and abiotic (nutrients, stressors etc.) components of a microorganism's microenvironment. This study investigated the impact of microm... Read More about Application of microfluidic systems in modelling impacts of environmental structure on stress-sensing by individual microbial cells.

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...

Evolution of the transport properties of soil aggregates and their relationship with soil organic carbon following land use changes (2021)
Journal Article

Aggregates are functional units to describe the impact of soil structural changes on physical and biogeochemical processes in soil. Both incubation and field experiments have shown that changing agricultural practices could reshape the intra-aggregat...

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...

Soil penetration by maize roots is negatively related to ethylene-induced thickening (2021)
Journal Article

Radial expansion is a classic response of roots to a mechanical impedance that has generally been assumed to aid penetration. We analysed the response of maize nodal roots to impedance to test the hypothesis that radial expansion is not related to th...

No-till alley cropping using leguminous trees biomass: a farmer- and eco-friendly sustainable alternative to shifting cultivation in the Amazonian periphery? (2021)
Journal Article

Agricultural growth is essential for both alleviating poverty and feeding the population of the Brazilian Amazonian periphery, where slash-and-burn agriculture continues to support the livelihoods of between 3.5 and 4 million people. We developed a n... Read More about No-till alley cropping using leguminous trees biomass: a farmer- and eco-friendly sustainable alternative to shifting cultivation in the Amazonian periphery?.

Relationship between soil carbon sequestration and the ability of soil aggregates to transport dissolved oxygen (2021)
Journal Article

A key finding in soil carbon studies over the past decade is that soil organic carbon (SOC) stabilization is not controlled by its molecular complexity or adsorption to clay, but by its physicochemical protection including occlusion in aggregates an...

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...

Could more efficient utilization of ecosystem services improve soil quality indicators to allow sustainable intensification of Amazonian family farming? (2021)
Journal Article

In the Amazonian periphery, there are sources of numerous disservices, including deforestation, loss of wildlife habitat and biodiversity erosion. However, there are great opportunities to adopt appropriate agricultural management practices to take a...

Frequency Versus Quantity: Phenotypic Response of Two Wheat Varieties to Water and Nitrogen Variability (2021)
Journal Article

Due to climate change, water availability will become increasingly variable, affecting nitrogen (N) availability. Therefore, we hypothesised watering frequency would have a greater impact on plant growth than quantity, affecting N availability, uptak...

Long‐term zero‐tillage enhances the protection of soil carbon in tropical agriculture (2021)
Journal Article

Contrasting tillage strategies not only affect the stability and formation of soil aggregates but also modify the concentration and thermostability of soil organic matter associated with soil aggregates. Understanding the thermostability and carbon r... Read More about Long‐term zero‐tillage enhances the protection of soil carbon in tropical agriculture.

Determination of wheat spike and spikelet architecture and grain traits using X-ray Computed Tomography imaging (2021)
Journal Article

© 2021, The Author(s). Background: Wheat spike architecture is a key determinant of multiple grain yield components and detailed examination of spike morphometric traits is beneficial to explain wheat grain yield and the effects of differing agronomy...

To till or not to till in a temperate ecosystem? Implications for climate change mitigation (2021)
Journal Article

The management of agricultural soils affect the composition and scale of their greenhouse gas (GHG) emissions. There is conflicting evidence on the effect of zero-tillage on carbon storage and GHG emissions. Here we assess the effects of zero-tillage...

The ability of maize roots to grow through compacted soil is not dependent on the amount of roots formed (2021)
Journal Article

© 2020 Elsevier B.V. Mechanical impedance is a primary constraint to root growth and hence the capture of soil resources. To investigate whether rooting depth and root length under mechanical impedance caused by compaction are correlated we evaluated...

Multiseriate cortical sclerenchyma enhance root penetration in compacted soils (2021)
Journal Article

Mechanical impedance limits soil exploration and resource capture by plant roots. We examine the role of root anatomy in regulating plant adaptation to mechanical impedance and identify a root anatomical phene in maize (Zea mays) and wheat (Triticum...

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...
