Mountain grasslands have recently been exposed to substantial changes in land use and climate the near future will likely face an increased frequency of extreme droughts. To date, how drought responses carbon (C) allocation, a key process C cycle, are affected by land-use mountain grassland is not known.We performed experimental summer on abandoned traditionally managed hay meadow traced fate recent assimilates through plant-soil continuum. We applied two
Droughts strongly affect carbon and nitrogen cycling in grasslands, with consequences for ecosystem productivity. Therefore, we investigated how experimental grassland communities interact groups of soil microorganisms. In particular, explored the mechanisms drought-induced decoupling plant photosynthesis microbial its recovery after rewetting. Our aim was to better understand root exudation during drought is linked pulses activity changes uptake We set up a mesocosm experiment on meadow...
Climate extremes and land-use changes can have major impacts on the carbon cycle of ecosystems. Their combined effects rarely been tested. We studied whether how abandonment traditionally managed mountain grassland resilience dynamics to drought. In an in situ common garden experiment located a subalpine meadow Austrian Central Alps, we exposed intact ecosystem monoliths from abandoned experimental early-summer drought measured responses gross primary productivity, respiration, phytomass its...
Abstract The supply of soil respiration with recent photoassimilates is an important and fast pathway for respiratory loss carbon (C). To date it unknown how drought land‐use change interactively influence the dynamics C in soil‐respired CO 2 . In situ common‐garden experiment, we exposed soil‐vegetation monoliths from a managed nearby abandoned mountain grassland to experimental drought. Based on two 13 pulse‐labelling campaigns, traced recently assimilated during drought, rewetting early...
Abstract Soilless culture systems offer an environmentally friendly and resource-efficient alternative to traditional cultivation fitting within the scheme of a circular economy. The objective this research was examine sustainable integration recycling fertilizers in hydroponic cultivation—creating nutrient cycling concept for horticultural cultivation. Using film technique (NFT), three recycling-based fertilizer variants were tested against standard synthetic mineral fertilization as...
Replacement of rock wool by organic substrates is considered to reduce the environmental impact, e.g., through energy savings during production and waste prevention, caused hydroponically produced crops. A suitable substrate for plant characterized an optimal composition air- water-filled pores. In our study, we used hemp fibers as alternative in order cultivate tomato plants hydroponics 36 weeks. The leaf area, length, yields, well quality fruits including soluble solid contents, dry weight...
Introduction Hydroponic vegetable cultivation is characterized by high intensity and frequent nitrogen fertilizer application, which related to greenhouse gas emissions, especially in the form of nitrous oxide (N 2 O). So far, there little knowledge about sources N O emissions from hydroponic systems, with few studies indicating that denitrification could play a major role. Methods Here, we use evidence an experiment tomato plants ( Solanum lycopersicum ) grown setup further shed light into...
Nitrous oxide (N 2 O) is considered as the most critical greenhouse gas (GHG) emitted by agricultural and horticultural food production. Hydroponic vegetable cultivation in systems has a high potential for N O emissions due to intense application of nitrogen-containing fertilizers. Previous studies on model hydroponic indicate that per unit area can be several times higher than typically found during field cultivation. However, reliable data from production-scale missing. Here we report our...
Numerous experiments have shown positive diversity effects on plant productivity, but little is known about related processes of carbon gain and allocation. We investigated these in a controlled environment (Montpellier European Ecotron) applying continuous 13CO2 label for three weeks to 12 soil-vegetation monoliths originating from grassland biodiversity experiment (Jena Experiment) representing two levels (4 16 sown species). Plant species richness did not affect community- species-level...
