Abstract The capacity for terrestrial ecosystems to sequester additional carbon (C) with rising CO 2 concentrations depends on soil nutrient availability 1,2 . Previous evidence suggested that mature forests growing phosphorus (P)-deprived soils had limited extra biomass under elevated (refs. 3–6 ), but uncertainty about ecosystem P cycling and its response represents a crucial bottleneck mechanistic prediction of the land C sink climate change 7 Here, by compiling first comprehensive budget...
Abstract Aims An essential task of agricultural systems is to improve internal phosphorus (P) recycling. Cover crops and tillage reduction can increase sustainability, but it not known whether stimulation the soil microbial community availability organic P pools. Methods In a field experiment in southwest Germany, effects winter cover crop mixture (vs. bare fallow) no-till non-inversion tillage) on P-cycling were assessed with soybean as main crop. Microbial biomass, phospholipid fatty acids...
Soil drying and rewetting (DRW) events are expected to occur at higher frequencies because of alterations in climate patterns. Readily extractable inorganic microbial soil phosphorus (P) pools may be affected due rapid changes water availability. We aimed determine how P dynamics by repeated DRW using a sandy grassland that regularly experiences DRW. In laboratory incubation study, the was exposed three cycles, with each cycle consisting two-day phase, three-day dryness phase four-day moist...
The importance of phosphorus (P) in regulating ecosystem responses to climate change has fostered P-cycle implementation land surface models, but their CO
The implementation of cover crops into a crop rotation can contribute to more sustainable soil management. For the improved decomposition residues, commercial inoculant Effective Microorganisms® (EM) is increasingly applied. Despite its extensive application, comprehensive studies on effect EM application processes are lacking, since rarely clean differentiation between an EM-effect (induced by living directly) or substrate accompanying substrate) made. To determine potential effects after...
Agriculture provides food to a still growing population but is major driver of the acceleration global nutrient flows, climate change, and biodiversity loss. Policies such as European Farm2Fork strategy aim mitigate environmental impact land-use by fostering organic farming. To assess long-term production we synthesized more than four decades research on agronomic performance oldest system comparison experiment conventional cropping systems (DOK experiment). Two (bioorganic biodynamic) are...
Organic farming may improve agroecosystems’ resilience against external stressors, favour below-ground biodiversity, soil health, and increase water holding capacity. At the same time, organic systems are repeatedly reported to have lower average crop yields than conventional systems. To date, global meta-analyses on include a diverse range of crops, but none them specifically focus arable with cereal-based rotations. Further, they not representative for specific European...
<title>Abstract</title> Climate change is having an impact on European agriculture and will increasingly do so in the future. Agroforestry, integration of trees or shrubs agricultural production systems, has been repeatedly voiced as a productive, sustainable resilient approach food production. Quantifying benefits agroforestry context resilience to current future climate Europe challenging. In online survey we gathered 60 experts’ assessment different forms (silvoarable, silvopastoral...
Phosphorus (P) is a non-renewable geological macronutrient that plays an essential role in food security. The excessive use of P as fertilizer and its subsequent diffuse loss leads to the deterioration water quality, eutrophication, biodiversity. Ecosystem process-based models are powerful tool depict cycle, investigate effects management practices climate change, ultimately assess policy interventions affect biogeochemical cycles. Of limited number agricultural production systems, none have...
Organic and conventional cropping systems differ in type amount of nitrogen (N) inputs. In organic only fertilizers are permitted, while both mineral used cropping. Fertilizer can affect N use efficiency a system, but contributions via symbiotic fixation changes soil stocks rarely quantified based on field data when computing nutrient budgets. We calculated an budget that accounts for these annual records period 35 years at the Swiss DOK (bio-Dynamic, bio-Organic, Konventionell) experiment....
Abstract Long-term field experiments (LTFEs) can provide an extensive overview on the effectiveness of phosphorus (P) management. In order to have a detailed insight into availability and distribution P in soil as affected by organic inorganic fertilizers (no P, triple-superphosphate (TSP), compost + TSP), samples collected at LTFE established 1998 Northern Germany different sampling dates depths were subjected characterization including double-lactate method (P-dl) standard test, degree...
Abstract Cover crops are grown between two main to reduce periods of bare fallow. In highly diverse crop rotations, the lengths break vary over time and consequently cover cropping management differs from year year. Long‐term field trials thus limited use because same approach only appears once in several years. This increases need better determine immediate effects different strategies on soil properties. study evaluated monitored temporal development properties six fields Eastern...
Abstract The authors studied the long‐term fatty replacement of bone marrow in 23 patients who had received radiation therapy for Hodgkin disease, with T1‐weighted magnetic resonance imaging and quantitative chemical shift imaging. images revealed a mostly homogeneous high‐signal‐intensity pattern, contrast to hypointense pattern nonirradiated marrow. degree was objectively assessed imaging, comparing age‐matched healthy volunteers. found an increase relative fat signal 37% thoracic spine...
Soil phosphorus (P) availability was assessed with four different soil P tests on seven soils of the Ultuna long-term field experiment (Sweden). These were (1) P-H2O (water extractable P); (2) P-H2OC10 upon 10 consecutive extractions); (3) P-AL (ammonium lactate P) and (4) P-CDGT (P desorbable using diffusive gradients in thin films). The suitability these to predict by correlation plant uptake (mean preceding 11 years) balancing (input vs. output plot level for a period 54 years). ability...
Abstract Increasing atmospheric CO 2 enhances plant biomass production and may thereby change nutrient concentrations in tissues. The objective of this study was to identify the effect elevated on grassland that have been grown for 16 years (1998–2013). at extensively managed Giessen FACE experiment, fumigated with ambient (aCO ; eCO +20%) harvested twice annually. Concentrations C, N, P, K, Ca, Mg, Mn, Fe, Cu Zn were determined separately grasses, forbs legumes. Under , concentration N...
