abstract = {While current global agriculture allows for efficient food production, it brings environmental disadvantages, which resulted in a lack of public acceptance. Digital technologies (e.g., technologies that enable precision agriculture) have been suggested as a potential solution to reconcile environmental sustainability and yield increases. By embedding digital technologies into holistic farming system visualized through mission statements, this study tests the effect of different intensities of digitization, as well as environmental arguments on the willingness to buy food produced by farms in Germany. We use a 4 x 4 repeated measure experimental design surveying a representative sample of 2,020 German citizens recruited online. Our research framework captures the farming system (comparing low intensity of digitalization for a small or organic farm and low, medium, and high intensity of digitalization for large or conventional farms) and environmental arguments (comparing no arguments, and altruistic, egoistic, and biospheric arguments). The results show a negative effect of digital technologies on willingness to buy. However, this relationship turns positive when introducing environmental arguments. Furthermore, there is a moderation effect for respondents’ attitudes towards technologies that varies depending on whether altruistic, egoistic, or biospheric concerns were stated. The results indicate that digital technologies can increase willingness to buy products from both large and conventional farms, but not to the level of small farms and organic farms.},

abstract = {Winter catch crops are grown to scavenge nutrients over a period of unfavorable growth conditions and to conserve nutrients for subsequent release to the following main crop. Since environmental conditions have a strong impact on the growth and nutrient capture in roots and shoots of individual catch crop species, we anticipated that mixtures will be more durable and efficient in nutrient capture due to compensatory effects among component species. We tested this hypothesis and determined the nitrogen and phosphorus accumulation in the shoots and roots of four catch crop species grown in pure vs. mixed stands at two sites for two or three years. Element concentrations were determined in the root and shoot biomass of each species and used to calculate the nutrient pool fixed in the root or shoot biomass. A qPCR-based technique was applied to quantify the root biomass of individual species based on species-specific DNA sequences. Despite considerable variation across environments, the overall plant biomass of white mustard (Sinapis alba), lacy phacelia (Phacelia tanacetifolia) and bristle oat (Avena strigosa) was similar and higher than that of Egyptian clover (Trifolium alexandrinum). While pure stands varied 6- to 24-fold in shoot biomass depending on environmental conditions, the variation was only ~3-fold for catch crop mixtures, with less pronounced variation in the root biomass. In general, the root biomass was comparable to the shoot biomass in each species. Roots contributed 26\textendash46% of the nitrogen and 36\textendash48% of the phosphorus to the total accumulation of these nutrients in the catch crop biomass, thus emphasizing the importance of plant roots as belowground nutrient pool for potential carry-over of nutrients to the subsequent crop. Although the mixture was mostly dominated by two of the four species, namely mustard and phacelia, it captured similar or even larger amounts of nutrients than the best-performing pure stand under any growth condition. This was the case for shoot- and for root-bound nutrients. Our results indicate that catch crop mixtures have higher durability than pure cultures to environmental variations. The amount of nitrogen captured by the mixture meets the average postharvest nitrogen that is left over by a wide range of cash crops, thus emphasizing that catch crop mixtures represent an efficient nutrient management tool in crop rotations.},

abstract = {Improving N cycling in agroecosystems is one of the key challenges in reducing the environmental footprint of agriculture. Further, uncertainty in precipitation makes crop water management relevant in regions where it has not been necessary thus far. Here, we focus on the potential of winter-killed catch crops (CCs) to reduce N leaching losses from N mineralization over the winter and from soil water management. We compared four single CCs (white mustard, phacelia, Egyptian clover and bristle oat) and two CC mixtures with 4 and 12 plant species (Mix4 and Mix12) with a fallow treatment. High-resolution soil mineral N (Nmin) monitoring in combination with the modelling of spatiotemporal dynamics served to assess N cycling under winter-killed CCs, while soil water was continuously monitored in the rooting zone. Catch crops depleted the residual Nmin pools by between 40 % and 72 % compared to the fallow. The amount of residual N uptake was lowest for clover and not significantly different among the other CCs. Catch crops that produce high N litter materials, such as clover and mustard leaves, showed an early N mineralization flush immediately after their termination and the highest leaching losses from litter mineralization over the winter. Except for clover, all CCs showed Nmin values between 18 % and 92 % higher on the sowing date of the following maize crop. However, only Mix12 was statistically significant. Catch crops depleted the soil water storage in the rooting zone during their growth in autumn and early winter, but preserved water later on when their residues covered the ground. The shallow incorporation of CC residues increased water storage capacity during the cropping season of the main crop even under reduced soil water availability. Hence, catch cropping is not just a simple plant cover for the winter but improves the growth conditions for the following crop with decreased N losses. Mixtures have been shown to compensate for the weaknesses of individual CC species in terms of nutrient capture, mineralization and transfer to the following main crop as well as for soil water management. Detailed knowledge about plant performance during growth and litter mineralization patterns is necessary to make optimal use of their potential.},

abstract = {Within the scope of this article is the development of a mathematical model of an insulating panel made from grain husks and the optimization of the panel regarding the thermal characteristics by using this self-developed thermodynamically model. The model comprises one husk as the smallest unit of the insulating panel. In order to solve the model analytically, the following relevant parameters have been determined: 

− husk geometry 

− density of the pure husk material 

− thermal conductivity of the pure husk material 

− emission coefficient of the husk's surface 

− convection coefficient inside the husks 

− density of the binder 

− thickness of the binder 

− thermal conductivity of the binder 



The solved model is validated with produced insulating panels out of grain husks. The optimization of the effective thermal conductivity λeff is done regarding the following parameters:

− the filling gas 

− the edge length of the husks 



According to the results of the simulation, by using Xenon as filling gas instead of air, the effective thermal conductivity λeff can be reduced by 21.6 %. The optimal value of the husk’s edge length a depends on the filling gas und therefore varies between 4 and 6 mm. The optimization of the edge length leads to a reduction of the effective thermal conductivity λeff of 7.5 %, according to the model.

When implementing individual calculated optimizations in real insulation boards, the thermal conductivity could be improved by up to 32 %. The project is funded by BMWi, the German ministry of economy and energy, and supervised by AiF, the working group of industrial research associations.},

Hierf\"{u}r standen Daten der elfmal j\"{a}hrlich stattfinden Milchleistungspr\"{u}fung (MLP) des Landeskuratoriums der Erzeugerringe f\"{u}r tierische Veredelung in Bayern e. V. (LKV) f\"{u}r den Zeitraum 2015\textendash2017 zur Verf\"{u}gung. Untersucht wurden 56 \"{o}kologische Milchviehbetriebe des Verbandes Naturland im bayerischen Alpenvorraum [31 Anbindehaltungsbetriebe mit Weide (AH+W), 18 Laufstallbetriebe mit Weide (LS+W), 7 Laufstallbetriebe mit Auslauf (LS+A)]. Verglichen wurden Herdengr\"{o}\sse, Milchleistung und Fett-Eiwei\ss-Quotient, Non-Return-Rate 90, Rastzeit und Zwischenkalbezeit sowie der Anteil der K\"{u}he mit Ketoserisiko. F\"{u}r das Jahr 2017 lagen Informationen bez\"{u}glich der Zusammensetzung des Grundfutters vor, weshalb der Fokus auf diesem Jahr lag. Im Sommer war die errechnete Energiedichte des Grundfutters zwischen den Haltungssystemen ann\"{a}hernd gleich, im Winter dagegen lag die errechnete Energiedichte des Grundfutters in AH+W signifikant unter jener in LS+W und LS+A. Die LS+A-Betriebe konnten eine signifikant h\"{o}here Milchleistung (p \< 0,001) sowie im Jahr 2017 einen geringeren Anteil ketosegef\"{a}hrdeter K\"{u}he vorweisen. K\"{u}he in LS+W- und LS+A-Betrieben hatten gegen\"{u}ber AH+W-Betrieben eine k\"{u}rzere Zwischenkalbezeit. Aus den Ergebnissen kann abgeleitet werden, dass Laufstallsysteme ohne Weide intensiver wirtschaften und somit bessere Leistungen erzielen, als Betriebe, deren K\"{u}he im Sommer einen \"{u}berwiegenden Teil der Ration auf der Weide aufnehmen. Die vorliegende Studie konnte Zusammenh\"{a}nge zwischen verschiedenen Haltungssystemen in der \"{o}kologischen Milchviehhaltung und der Milchleistung, dem Ketoserisiko sowie Parametern zum Fortpflanzungsgeschehen aufzeigen.



The aim of this study was to examine standardized milk yield, metabolism and fertility parameters in organic dairy farming for correlations to different husbandry systems. For this purpose, data related to milk yielding provided eleven times a year by the “Landeskuratorium der Erzeugerringe f\"{u}r tierische Veredelung in Bayern e. V. (LKV)” for the period 2015\textendash2017 were available. Fifty-six organic dairy farms of the Naturland association in the Bavarian Alpine foothills [31 Tie-stall farms with grazing (AH+W), 18 free stall housing systems with grazing (LS+W), 7 free stall housing systems with free-range area (LS+A)] were analysed. Herd size, milk yield and milk constituents, non-return rate at 90 days, calving to first-service interval and calving interval, as well as the proportion of cows at risk of ketosis were compared. Focus of the study was the year 2017, as data of the staple feed was available for this year. The calculated energy density of the staple feed in summer was similar between the housing systems, but in winter it was lower for AH+W farms than for LS+W and LS+A. LS+A farms showed significantly higher milk yield (p \< 0.001) and a lower proportion of cows at risk of ketosis in 2017. Compared to AH+W farms, cows in LS+W and LS+A farms had a shorter calving interval. It can be deduced that free stall housing systems without grazing are more intensive and thus achieve better performance than farms whose cows consume a major part of the ration grazing in summer. In conclusion, the present study was able to show correlations between different housing systems in organic dairy farming and milk yield, ketosis risk and fertility.},

The species has shown a dramatic decline in the past decade in both countries and in neighbouring

rendlei populations in Luxembourg and its bordering regions in Belgium, Germany, and

France and to determine whether regions and populations differ in plant morphology and

site ecology. At each survey site plant material from A. rendlei was collected and the species’

population density was calculated. Furthermore, soil samples were taken, and the floristic

composition of the sites overall was analysed. Within the study area, mean density of A.

rendlei plants per population showed extensive variation. The presence of the species could

only be confirmed in half of the known sites, out of which more than 50% were meadows.

In reference to plant morphology, Luxemburgish populations were similar to the Belgian

ones, except for one population in the south of Luxembourg that displayed many similarities

to French populations. In the German population the internodia were shorter than in

the other studied populations. Plant size as well as leaf length and the leaf length-width ratio

increased from Belgium to Luxembourg and France. The conclusions include management

and further research proposals. Based on our results as well as those of further investigations

that are required, the decline of Alopecurus rendlei should be counteracted.},

abstract = {Cereal crop yield comprises interrelated components, among which the number of tillers is highly responsive to nitrogen fertilization. We addressed the hypothesis of whether the supply of different nitrogen forms can be employed to manipulate the tiller number in cereal crops. Relative to urea or ammonium, exclusive supply of nitrate increased tiller number in hydroponically-grown barley plants. Thereby, tiller number correlated positively with the root-to-shoot translocation rate of endogenous cytokinins. External supply of a synthetic cytokinin analog further stimulated tillering in nitrate-containing but not in urea-containing nutrient solution. When the cytokinin analog 6-benzylaminopurine riboside was externally supplied to roots, its translocation to shoots was 2.5 times higher in presence of nitrate than in presence of urea or ammonium, suggesting that cytokinin loading into the xylem is affected by different nitrogen forms. We then translated this finding to field scale, cultivated winter wheat in four environments, and confirmed that nitrate fertilization significantly increased tiller number in a dose-dependent manner. As assessed in 22 winter wheat cultivars, nitrogen form-dependent tiller formation was subject to substantial genotypic variation. We conclude that cytokinin-mediated signaling effects of fertilizer nitrogen forms can be employed as a management tool to regulate the tiller number in cereal crops.},

abstract = {While the main objective in energy production is the reduction of fossil fuels, CO2-production by fossil fuels increased over the last decade. Therefore the need for usage of regenerative energies is obvious. Biogas plants are advantageous because they can be used with-out spatial limitation and their substrate is abundant ubiquitously as it covers the whole range of produced organic matter from photosynthesis, municipal, industri-al and animal waste. Although the need for optimization strategies is given, the fermentation process in biogas plants is complex and therefore traditional optimization approaches are cumbersome and carry the risk of com-plete plant failure. In this paper the optimization poten-tial of the ADM1, which represents a detailed description of the anaerobic digestion process is analysed and com-pared to the standard ADM1 setup. Technical parame-ters like substrate composition and dilution rate are optimized to yield a high methane gas flow. It is shown that the optimization of substrate composition has a direct impact on the maximum applicable dilution rate. It is also shown that the feeding rate can be increased to yield higher productivities with optimized substrate compositions.},

Two crossing trials with the diploid accessions 'Bona' (BON) and 'Hungary 2' (HUN2) should specify maternally inherited cytoplasmic male sterility (CMS). Progeny thereof showed increased PS. BON as mother (BH) entailed means of 30 and 22% PS, versus 8% and 20% after reciprocal crossings. Backcrosses of BH with HUN2 in paternal and maternal direction revealed increasing mean PS (24% and 32%), without verification of CMS. A split plot design of 100 individuals treated with four chemical gametocides analyzed PS, seed set, germination rate and whole plant damage. Tri--iodobenzoic acid caused the highest PS (43%). Progeny of two plants (2x, 4x) with degenerated anthers without pollen, showed 100% PS either in tetraploid F1 and F2 (4% and 11%) or in diploid F2 and F3 (26% and 23%). High temperature (30/28°C day/night) decreased the male fertility to some extent.},

abstract = {Catch crops increase plant species richness in crop rotations, but are most often grown as pure stands. Here, we investigate the impacts of increasing plant diversity in catch crop rotations on rhizosphere C input and microbial utilization. Mustard (Sinapis alba L.) planted as a single cultivar was compared to diversified catch crop mixtures of four (Mix4) or 12 species (Mix12). We traced the C transfer from shoots to roots towards the soil microbial community and the soil respiration in a 13C pulse labelling field experiment. Net CO2-C uptake from the atmosphere increased by two times in mix 4 and more than three times in mix 12. Higher net ecosystem C production was linked to increasing catch crop diversity and increased belowground transfer rates of recently fixed photoassimilates. The higher rhizosphere C input stimulated the growth and activity of the soil microbiome, which was investigated by phospholipid fatty acid (PLFA) analyses. Total microbial biomass increased from 14 to 22 g m−2 as compared to the fallow and was 18 and 8% higher for mix 12 and mix 4 as compared to mustard. In particular, the fungal and actinobacterial communities profited the most from the higher belowground C input and their biomass increased by 3.4 and 1.3 times as compared to the fallow. The residence time of the 13C pulse, traced in the CO2 flux from the soil environment, increased with plant diversity by up to 1.8 times. The results of this study suggest positive impacts of plant diversity on C cycling by higher atmospheric C uptake, higher transport rates towards the rhizosphere, higher microbial incorporation and prolonged residence time in the soil environment. We conclude that diversified catch crop mixtures improve the efficiency of C cycling in cropping systems and provide a promising tool for sustainable soil management.},
