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)....
Information on how crop yields are affected by weather variations and extreme is needed to develop climate adaptation measures for arable cropping systems. Here, we analysed the effects of anomalies soil texture yield across Sweden from 1965 2020. The aims this study were (i) assess temperature precipitation major field crops Sweden, (ii) quantify responses vary along north-south gradient (iii) elucidate impacts anomalies. We used daily mean air temperature, total precipitation, data public...
Increasing crop species diversity within a region could improve agricultural sustainability, but knowledge of the spatiotemporal variation and how this is related to pedo-climatic conditions limited. In current study, we used historical data records quantify conditions, developed over time at national regional scale in Sweden between 1965 2019. Crop was quantified using exponent Shannon index. We found spatial differences across country, with significant increase from north south, showing...
Roots grow in a highly heterogeneous physical environment due to the spatial complexity of soil structure. Thereby, root growth zone repeatedly experiences stress such as hypoxia or increased penetration resistance. To mimic variable surrounding zone, we subjected pea and wheat seedlings periodic stress. One day resistance reduced elongation rate both species by at least 20 %. Upon release, could recover within one day, while no recovery occurred wheat. Similarly, diameter 15 % resistance,...
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...
Abstract. Drought poses increasing challenges to global food production. 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. Here, we evaluate potential Sentinel-2 reveal interactions plant-growth parameters during...
<p>Physical properties of soil such as penetration resistance and oxygen concentration air strongly influence root system development in plants. Soils typically exhibit considerable spatial temporal fluctuations due to wetting-drying cycles, small-scale differences compactness or hotspots biological activity. Hence, roots a single plant are exposed different physical environments thus stresses during their growth through the profile. Plants known adjust these spatiotemporal...
<p><strong>Objective</strong></p><p>Diverse cropping systems are associated with multiple ecosystem services and suggested to alleviate the effects of drought heat stress. The magnitude frequency extreme weather events projected increase in future due climate change, diverse might therefore become key for food security. However, there is still limited information on spatiotemporal variation crop species diversity how it...
