Abstract We use a unique set of terrestrial experiments to demonstrate how soil management practises result in emergence distinct associations between physical structure and biological functions. These have significant effect on the flux, resilience efficiency nutrient delivery plants (including water). Physical structure, determining air–water balance as well transport rates, is influenced by interventions. Contrasting emergent structures exert selective pressures upon microbiome...
Soil delivers fundamental ecosystem functions via interactions between physical and biological processes mediated by soil structure. The structure of is also dynamic modified natural factors management intervention. aim this study was to investigate the effects different cropping systems on at contrasting spatial scales. Three were studied in replicated plot field experiments involving varying degrees plant-derived inputs soil, viz. perennial (grassland), annual (arable), no-plant control...
Abstract Cover crops (plants grown in an agricultural rotation between cash crops) can significantly improve soil quality via sequestering carbon, retaining nutrients, decreasing erosion, and maintaining belowground biodiversity. However, little is known about the effects of such plants upon structure. The aim study was to assess impact four species typically used as cover which have contrasting root architecture ( viz . clover, black oat, phacelia, tillage radish) on structural genesis...
We studied the effects of Phacelia tanacetifolia, increasingly used as a cover-crop species in arable agricultural systems, upon soil structural properties context two contrasting textures. hypothesised there would be differential plants structure contingent on texture. A sandy-loam and clay were destructured by passing through 2 mm sieves, planted with replicated pot experiment, associated unplanted controls. X-ray Computed Tomography was to visualise quantify pore networks 3D. For soil, no...
Soil structure is an indicator of soil quality and its alterations following cropping system conversion or fertilization change evolve slowly. How such vary with scale remains elusive. We investigated this based on the Rothamsted long-term wheat experiment (since 1843) in UK. Triplicate cores 7 cm high 10 diameter were taken from plots that have been under different fertilizations returned to natural woodland for more than one century imaging using X-ray computed tomography voxel size being...
Abstract Agricultural practices can have significant effects on the physical and biological properties of soil. The aim this study was to understand how structure a compromised soil, arising from long‐term bare‐fallow management, modified by adopting different field management practices. We hypothesized that changing agricultural arable or grassland would influence modification pore via an increase in porosity connectivity, more homogenous distribution sizes, change exerts rapid evolution...
Over the past three decades colonial ascidian Didemnum vexillum has been expanding its global range, significantly impacting marine habitats and aquaculture facilities. What biological features make D. so highly invasive? Here, we show that juxtaposed allogeneic colony fragments (‘ramets’) may, initially, form chimeric entities. Subsequently, zooids of differing genotypes within such chimeras coordinately retreat away from fusion zones. A few days following post-fusion movements there is...
<title>Abstract</title> Unsustainable practices are degrading over 40% of global agricultural soils, which in turn is driving climate change, biodiversity loss, and food water insecurity at a planetary scale. We don’t know if further degradation will be proportionate or there tipping point that result catastrophic loss function. While increasing soil organic carbon stocks can restore functions, lack consensus on how levels maintained, we understand impacts These uncertainties the most...
&lt;p&gt;Soil organic matter is associated with important biological and physical functions. There are many theories to interpret this association, as yet there not a fully developed understanding linking soil properties nutritional management in arable systems.&lt;/p&gt;&lt;p&gt;We used X-ray computed tomography analyse structure at the core aggregate scale on Broadbalk long term experiment (Hertfordshire, England). Here we present results of treatments that have...
