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...
Summary Plants modify their root hydraulics to maintain water status and strategically use soil water, but how they achieve this in the field conditions remains elusive. We developed a method measure calculate daily uptake, potential, radial permeability at different depths wheat ( Triticum aestivum L. ) permanent grassland dominated by ryegrass Lolium perenne ). During drying processes, both plant systems reduced of shallow roots limit topsoil while increasing subsoil enhance extraction....
Soil structure is a crucial soil physical property that determines soil's ability to support the growth and development of plants. compaction modifies by reducing pore space between particles thereby leading denser fabric. This often limits root increasing strength penetration resistance requiring roots increase energy needed elongate explore deeper soil. Apart from compaction, moisture also plays an important role in determining how resistant penetration. An understanding synergy both...
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...
Seed germination is a crucial stage in plant development, intricately regulated by various environmental stimuli. Understanding these interactions essential for optimizing planting and seedling management but remains challenging due to the trade-off effects of factors on process. We proposed new conceptual model viewing seed as dynamic process physiological dimension, with influence heterogeneity characterized speed dispersion coefficient. To validate model, we conducted field experiments...
Modifying farming practices combined with breeding has the potential to improve water and nutrient use efficiency by regulating root growth, but achieving this goal requires phenotyping roots, including their architecture ability take up nutrients from different soil layers. This is challenging due difficulty of in situ measurement opaqueness soil. Using stable isotopes coring, we calculated change uptake summer maize response planting density nitrogen fertilization a 2-year field...
Root system architecture (RSA) refers to the spatial distribution and extended morphology of plant root systems in soil. RSA not only determines ability plants obtain water nutrients but also affects other ecological functions. Hence, it plays a dominant role overall health plants. The study can provide insight into absorption fertilizers, relationship between above- belowground parts, physiological functions Therefore, this paper summarizes research on morphology, functionality, plasticity...
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...
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...
Non-destructive phenotyping of roots and measurement root water uptake from different soil layers in the field are vital for improving management facilitating development drought-resistant crop varieties, but difficult because their opaqueness. As a result, indirect methods using easy-to-measure variables such as content have been used alternatives. However, inherent errors could undermine robustness reliability these methods. This paper proposes new method to bridge this knowledge gap by...
Biogeochemical reactions occurring in soil pore space underpin gaseous emissions measured at macroscopic scales but are difficult to quantify due their complexity and heterogeneity. We develop a volumetric-average method calculate aerobic respiration rates analytically from with microscopic structure represented explicitly. Soil water content the model is result of processes, it nonlinearly coupled temperature other factors. Since many biogeochemical driven by oxygen (O 2 ) which must...
In water-scarce regions, alternate-furrow irrigation (AFI)—alternately wetting half of the plant roots—has proven to be an effective water-saving approach without compromising yield. However, extent which AFI with wastewater affects N cycling genes remains poorly studied. We aimed investigate changes in main transformation processes, bacterial and fungal community composition, as well relative abundance cycle-associated soil receiving swine wastewater. The experimental plan included three...

<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...
