    Abstract Climate change and increased extraction of agricultural residues for bioenergy can adversely affect soil fertility. A more accurate understanding of biomass that remains in or on arable soil is necessary to improve results of carbon (C) balances of cropped land. Mechanical and manual harvesting of winter wheat grain and material other than grain (MOG) were carried out at three field stations in Thuringia, Germany, in 2012 and 2013. We compared various methods of harvesting MOG, which resulted in different straw/grain ratios (SGR) and their effect on C balancing. For all experiments, the total biomass yield and SGR were larger for manual than mechanical harvesting. Substantial differences in SGR resulted for the various methods of mechanical MOG recovery. Surprisingly, methods of harvesting without biomass deposition to the soil surface cannot be regarded as more accurate in general than those with intermediate MOG deposition. Using these SGRs to determine the amount of MOG available for the maintenance of soil organic carbon (SOC) resulted in an underestimate of the actual biomass by up to 47%. For stubble heights of 5–15 cm, a mean of 8–22% of MOG remained in the field as stubble. Thus, the method of MOG assessment should be considered for SGR values used to calculate the C input as a model parameter. We demonstrated that SOC is underestimated by up to 24% when the simplified C turnover model CANDY Carbon Balance (CCB) is not parameterized correctly. HIGHLIGHTS: How do specific straw/grain ratios (SGR) of wheat change modelled carbon accumulation? Removal of straw from arable soil for energy provision will gain more attention. Default SGR of the selected carbon model underestimates biomass input to soil by ∼47%. Consequently carbon accumulation is underestimated by up to 24%.

    Abstract Many countries consider the lifting of restrictions of social contacts (RSC). We quantify the effects of RSC for Germany. We initially employ a purely statistical approach to predicting prevalence of COVID19 if RSC were upheld after April 20. We employ these findings and feed them into our theoretical model. We find that the peak of the number of sick individuals would be reached already by mid-April. The number of sick individuals would fall below 1,000 at the beginning of July. When restrictions are lifted completely on April 20, the number of sick should rise quickly again from around April 27. A balance between economic and individual costs of RSC and public health objectives consists in lifting RSC for activities that have high economic benefits but low health costs. In the absence of large-scale representative testing of CoV-2 infections, these activities can most easily be identified if federal states of Germany adopted exit strategies that differ across states.

  9. Article: Do farmers in Germany exploit the potential yield and nitrogen benefits from preceding oilseed rape in winter wheat cultivation?

    Abstract Field experiments show that wheat grown after oilseed rape (OSR) achieves higher yield levels, while the nitrogen (N) application is reduced. However, field experiment data are based on few locations with optimised management. We analysed a large dataset based on farm data to assess the true extent of break crop benefits (BCB) for yield and N fertilisation within German commercial farming. Across all German states and years, average yield of wheat preceded by OSR was 0.56 Mg ha−1 higher than yield of wheat preceded by cereals (7.09 Mg ha−1), although considerable variation between regions was observed. Mean N application across all states to wheat after OSR was 5 kg ha−1 lower than to wheat after cereals. Choice of wheat types for different end uses (bread flour or animal feed) showed higher (0.77 Mg ha−1) or lower (0.44 Mg ha−1) BCB for yield of wheat cultivated after OSR compared with after cereals. The calculated BCB for yield and N fertilisation were lower than expected from dedicated field experiments and fertiliser recommendations. Thus the advantages of OSR as a preceding crop are generally utilised by commercial farmers in Germany but there is room for improvement.

    Abstract Background: In refractory cardiac arrest, with cardiopulmonary resuscitation (CPR) for more than 30 min, chances of survival are small. Extracorporeal cardiopulmonary resuscitation (ECPR) is an option for certain patients with cardiac arrest. The aim of this study was to evaluate characteristics of patients selected for ECPR.
    Methods: Anonymised data of adult patients suffering refractory cardiac arrest, transported with ongoing CPR to an ED of a tertiary care centre between 2002 and 2012 were analysed. Outcome measure was the selection for ECPR. Secondary outcome was 180 days survival in good neurological condition.
    Results: Overall, 239 patients fulfilled the inclusion criteria. ECPR was initiated in seven patients. Patients treated with ECPR were younger (46 vs 60 years; p=0.04), had shorter intervals before CPR was started (0 vs 1 min; p=0.013), faster admissions at the ED (38 vs 56 min; p=0.31) and lower blood glucose levels on admission (14 vs 21 mmol/L; p=0.018). Survival to discharge in good neurological condition was achieved in 14 (6%) of all patients. One patient in the ECPR group survived in excellent neurological condition. Age was independently associated with the selection for ECPR (OR 0.07; 95% CI 0.01 to 0.85; p=0.037).
    Conclusions: Emergency extracorporeal life support was used for a highly selected group of patients in refractory cardiac arrest. Several parameters were associated with the decision, but only age was independently associated with the selection for ECPR. The patient selection resulting in a survival of one patient out of seven treated seems reasonable. Randomised controlled trials evaluating the age limit as selection criteria are urgently needed to confirm these findings.
