Plant roots are major transmitters of atmospheric carbon into soil. The rhizosphere, the soil volume around living influenced by root activities, represents hotspots for organic inputs, microbial activity, and turnover. Rhizosphere processes remain poorly understood observation key mechanisms transfer protection in intact rhizosphere microenvironments challenging. We deciphered fate photosynthesis-derived (OC) wheat combining stable isotope labeling at field scale with high-resolution...
Abstract One of the critical challenges in agriculture is enhancing yield without compromising its foundation, a healthy environment and, particularly, soils. Hence, there an urgent need to identify management practices that simultaneously support soil health and production help achieve environmentally sound systems. To investigate how influences under realistic agronomic conditions, we conducted on‐farm study involving 60 wheat fields managed conventionally, no‐till or organically. We...
Root biomass is one of the most relevant root parameters for studies plant response to environmental change, soil carbon modeling or estimations sequestration. A major source error in quantification agricultural crops field presence extraneous organic matter soil: dead roots from previous crops, weed roots, incorporated above ground residues and amendments, remnants fauna. Using isotopic difference between recent maize predominantly C3-derived matter, we determined proportions total samples...
Soils store significant amounts of carbon (C) and thus can play a critical role for mitigating climate change. Crop roots represent the main C source in agricultural soils are particularly important long-term storage agroecosystems. To evaluate potential different farming systems to contribute soil sequestration change mitigation, it is great importance gain better understanding factors influencing root allocation distribution. So far, still unclear how varies among whether choice management...
Interactions between model parameters and low spatiotemporal resolution of available data mean that conventional soil organic carbon (SOC) models are often affected by equifinality, with consequent uncertainty in SOC forecasts. Estimation belowground C inputs is another major source modelling. Models usually calibrated on stocks fluxes from long‐term experiments (LTEs), whereas other point not used for constraining the parameters. We an agricultural (>65 years) fertilization experiment to...
Abstract The European Commission has set targets for a reduction in nutrient losses by at least 50% and fertiliser use 20% 2030 while ensuring no deterioration soil fertility. Within the mandate of Joint Programme EJP Soil ‘Towards climate‐smart sustainable management agricultural soils’, objective this study was to assess current fertilisation practices across Europe discuss potential harmonisation methodologies as strategy reduce loss overall use. A stocktake methods delivering advice took...
Abstract. Drought poses increasing challenges to global food production. Knowledge about the influence of drought on crop development and role soil properties for severity is important in risk analysis mitigating impacts at landscape level. Here, we tested if satellite images from Sentinel-2 could be used assess responses scale what were. As a case study, assessed winter wheat growth 13 fields belonging commercial farmers southern Sweden dry year (2018) with normal weather conditions (2021)....
ABSTRACT Ensuring food security through sustainable practices while reducing greenhouse gas emissions are key challenges in modern agriculture. Utilising genetic variability within a crop species to identify varieties with higher root biomass carbon (C) could help address these challenges. It is thus crucial quantify and understand intra‐specific above‐ belowground performance under varying environmental conditions. The study objectives were to: (a) depth distribution different winter wheat...
Phosphorus (P) management in agroecosystems is driven by opposing requirements agronomy, ecology, and environmental protection. The widely used maintenance P fertilization strategy relies on critical concentrations of soil test (STP), which should cause the lowest possible impact environment while still ensuring optimal yield. While both availability crop yields are fundamentally related to pedoclimatic conditions, little known about extent climate variables control STP. official guidelines...
Climate change will strongly influence agricultural practices in the future. In order to promote resource-efficient agriculture, it is important analyse impact of climate variation on crop yields. this study, we report yields spring wheat, winter barley, maize, potato and sugar beet from long-term rotation fertilization experiment Demo Switzerland analyze their response different variables (e.g., annual seasonal temperature, precipitation, evapotranspiration, number heat days heavy...
Abstract Many European cropped soils have high soil test P (STP) values in the top because of accumulation over many years fertilizer application. This should allow to save applications for some without STP decreasing a level that might negatively impact crop yield. However, way develops under omitted application is not well understood. We examined development timeframes between 7 and 46 on 96 unfertilized treatments (P0 treatments) 43 long‐term field experiments, using five different...
Abstract This study takes advantage of Swiss long-term field experiments (> 30 yrs) with different K fertilization rates at three sites to (i) test the possibility generalize linear relationships between extracts (ammonium acetate, K-AA; ammonium acetate EDTA, K-AAE; water, K-H 2 O; and water saturated CO , K-CO ), (ii) determine effect on soil exchangeable K, (iii) shoot biomass grain yield winter wheat, (iv) analyze derive a critical value, (v) plant (K c ) dilution curve as function...
Drought can severely limit plant growth, and in turn crop productivity, poses challenges to global food production. Plant growth be measured with the Green Leaf Area Index (GLAI), satellite images offer opportunities estimate GLAI at field landscape scales. Analysing satellite-estimated development level could reveal new insights into how soil characteristics influence performance under various weather conditions, which provide information on mitigate impacts of extreme weather. In this...
Climate change mitigation and adaptation is a major challenge of modern agriculture. Increasing the incorporation atmospheric carbon (C) as organic matter into soils through improved crop management seems to be promising agricultural option for supporting climate mitigation. In order build up soil C increased inputs are urgently needed. soils, roots source pivotal long-term storage compared aboveground biomass their turnover 2 3 times slower. This suggests, that variety selection towards...

Knowledge about the influence of drought on crop development and role soil properties in risk analysis mitigating impacts at landscape level is important guide climate change adaptation. Satellite earth observations can provide area-wide insights into growth processes that may help identify factors quantify vulnerability drought.
