Nitrogen (N) pollution of groundwater bodies is often a result of high livestock densities combined with use of mineral N fertilisers in Northwest Germany, specifically in combination with sandy soils and high amounts of precipitation. Organic agriculture is discussed as an alternative management practice reducing nitrogen losses due to area-based livestock densities and waiving of mineral N fertilisers. A field trial with integrated ceramic suction cups over three years showed potential for reduced N loads under conventional management specifically with organic fertilisation. Now, the field trial is under transition into organic farming with promising additional benefits for drinking water quality and the great potential to develop optimised N management strategies.
Objectives: Among varied challenges of COVID-19, challenges in food and nutrition security world-over are critical. We compared the nutritional policy responses in India and Germany since both countries differ on the Human Development Index, yet both have committed to the G20 common policy response to COVID-19, besides the comparability of two large and heterogeneously populated countries, both having democratic governments.
Methods: Policy research publications were reviewed using qualitative meta-policy approach. We used comparative case-study. Recent food and nutrition policies of G20 nations of India and Germany were evaluated.
Results: India has primarily targeted her public distribution system and Germany has primarily targeted her food markets in order to manage the food and nutrition security in response to COVID-19. Both countries are coordinating additional associated nutritional policies, policies and strategies to effect an integrated sectoral approach to COVID-19 management. Both are using corrective measures of the process management strategies as well. However, the Indian management of micronutrient security for her population has over COVID-19 times acerbated and the German loan management to nutrition and agricultural small-scale industry appears to be functioning sub-optimally.
Conclusions: Our analysis indicates both India and Germany have responded to COVID-19 in a timely and appropriate manner regarding the food and nutrition security measures. Even so not all measures employed to tackle COVID-19 food and nutrition security have been effectively implemented, It appears, that both countries are using integrated policy in their nutrition and food security response to COVID-19.

Studies on nutrition have historically concentrated on food-shortages and over-nutrition. The physiological states of feeling hungry or being satiated and its dynamics in food choices, dietary patterns, and nutritional behavior, have not been the focus of many studies. Currently, visual analytic using easy-to-use tooling offers applicability in a wide-range of disciplines. In this interdisciplinary pilot-study we tested a novel visual analytic software to assess dietary patterns and food choices for greater understanding of nutritional behavior when hungry and when satiated. We developed software toolchain and tested the hypotheses that there is no difference between visual search patterns of dishes 1) when hungry and when satiated and 2) in being vegetarian and non-vegetarian. Results indicate that food choices can be deviant from dietary patterns but correlate slightly with dish-gazing. Further, scene perception probably could vary between being hungry and satiated. Understanding t he complicated relationship between scene perception and nutritional behavioral patterns and scaling up this pilot-study to a full-study using our introduced software approaches is indispensable.
Qualitätsmanagement in der Ernährungswirtschaft : Qualität, Sicherheit und Nachhaltigkeit umsetzen
(2020)
Unverzichtbar für alle, die sich im Lebensmittelsektor mit Qualitätsmanagement auseinandersetzen.
QM ist in der Ernährungswirtschaft von Anfang an wegen der damit untrennbar verbundenen Anforderungen an die Lebensmittelsicherheit von besonderer Bedeutung. Zunehmend verändern sich die Rahmenbedingungen, mit denen das Qualitätsmanagement in der Ernährungswirtschaft konfrontiert ist: beginnend bei der wachsenden Komplexität und Differenziertheit der Verbraucheransprüche, über die weltweite Verflechtung der Liefer- und Absatzbeziehungen, die dynamische Entwicklung wissenschaftlich-technischer Erkenntnisse und deren Auswirkungen auf die Lebensmittelproduktion bis hin zu der immer drängenderen Notwendigkeit, im Lebensmittelsektor nachhaltiger zu wirtschaften.
Vor dem Hintergrund dieser Entwicklungen werden in dem vorliegenden Werk relevante Fragen rund um das Themengebiet Qualitätsmanagement in der Ernährungswirtschaft aufgegriffen und praxisorientiert beantwortet. Dazu gehören "klassische" Themen, wie Hygiene, HACCP und Risikoprävention ebenso wie Rückverfolgbarkeit und Krisenmanagement, und auch Fragen, die erst seit wenigen Jahren in den Vordergrund getreten sind, wie Allergenmanagement, Food Defense und Food Fraud. Darüber hinaus werden wichtige Methoden, Werkzeuge und Techniken des Qualitätsmanagements erläutert, relevante Institutionen sowie Normen und Standards der Ernährungswirtschaft vorgestellt und eingeordnet.
Dieses Buch
- bietet einen umfassenden Überblick und navigiert sicher durch diesen hochkomplexen Themenbereich,
- zeigt, was alles bei der Umsetzung eines Qualitätsmanagementsystems zu beachten ist und berücksichtigt dabei die speziellen Anforderungen im Lebensmittelbereich,
- liefert praktischen Werkzeugkasten zur Umsetzung.
Background and Aims: Agronomic biofortification of food crops with iodine may improve the dietary intake of this trace element, which is essential for human development and health. So far, little is known about the suitability of this technique in pome fruits. The objectives of this study were (1) to investigate uptake and translocation of exogenously applied iodine in apple trees, (2) to identify possible strategies of iodine biofortification for this type of fruit, and (3) to evaluate interactions between foliar applied iodine and selenium.
Methods: Apple trees were cultivated in a plastic tunnel for two growing seasons. Iodine was applied via leaves or substrate. During the 2nd year, simultaneous foliar application of iodine and selenium were tested as well. At harvest time, iodine and selenium content in leaves and fruits were determined. The phytoavailable iodine concentration in the growing medium was analyzed following an extraction with calcium chloride. In addition, the dynamics of iodine applied as potassium iodide and iodate in a peat‐based substrate was investigated in an incubation experiment without plants.
Results: The iodine concentration in washed apples increased more than 100‐fold, valuing around 50 µg (100 g FM)−1 by foliar application of iodine as compared to the control treatment. However, this level was only achieved in fruits which were directly wetted by the spray solution. The translocation of leaf‐absorbed iodine to fruits was negligible. Following a substrate fertilization, the fruit iodine content remained rather low due to a strong retention of iodine in the growing medium. When using foliar sprays, the addition of selenium did not affect the iodine enrichment of the apple fruits.
Conclusions: Foliar fertilization of iodine seems to be a promising method to biofortify apples with iodine. The level of I achieved in apple fruits by means of foliar fertilization can significantly contribute to the daily I intake requirement of humans.
The aim of the study was to examine different pH parameters, such as variations throughout the day, depending on differing concentrate feed proportions. Moreover, special attention was payed to individual variation in microbial efficiencies (microbial crude protein/fermented organic matter) and their relation to ruminal pH, nutrient flows and digestibilities. For this, cows were grouped according to microbial efficiency (more, n = 5, vs. less efficient cows, n = 4). After calving, thirteen ruminally cannulated pluriparous cows, including nine duodenally cannulated animals, were divided into groups offered rations with a lower (35% on dry matter basis, n = 7) or a higher (60% on dry matter basis, n = 6) concentrate feed proportion. Ruminal pH parameters were assessed continuously by using intraruminal probes. Nutrient flows, nutrient digestibility and microbial efficiency were determined for duodenally cannulated cows. For most ruminal pH parameters it seemed that individual variability was higher than the treatment effect. However, a positive relationship between actual concentrate intake and diurnal pH fluctuations was found. Besides, the effect of individually different microbial efficiencies was assessed. Again, there were no group differences for pH parameters. However, nutrient flows were significantly higher in more efficient cows, whereas digestibilities were lower in in more efficient cows.
Gebäude beanspruchen Ressourcen und verändern die Umwelt. Die Landwirtschaft benötigt oftmals großvolumige Gebäude. Eine nachhaltigere landwirtschaftliche Baukultur wäre deshalb begrüßenswert. Für das agrarische Bauen könnte eine verstärkte Verwendung des Rohstoffs Holz eine Perspektive darstellen. Holz überzeugt durch zahlreiche ökologische Vorteile wie die langfristige Kohlenstoffbindung oder eine einfache Recycelbarkeit. In Deutschland spielt Holz beim landwirtschaftlichen Bauen allerdings eine immer geringere Rolle. Diese Studie stellt Meinungsbilder deutscher LandwirtInnen zum Holzeinsatz beim Stallbau zusammen. Es wurden zehn Gruppendiskussionen zum Themenfeld landwirtschaftliche Baukultur in verschiedenen deutschen Schwerpunktregionen der Rinderhaltung gestaltet. Die Auswertungen zeigen, dass die LandwirtInnen weitestgehend die optische Wirkung von Holz schätzen, aber häufig an der Dauerhaftigkeit von Holzställen zweifeln.
Um die Milchviehhaltung gibt es seit einigen Jahren auch eine öffentliche Tierwohldiskussion. Zwei Aspekte sind dabei immer wieder Gegenstand der Debatte: Die Anbindehaltung und der Weidegang. Auf Basis von qualitativen Interviews mit zivilgesellschaftlichen Verbänden und landwirtschaftlichen Verbänden zum Thema Tierwohl in der Milchviehwirtschaft wurden die Einstellungen und die Argumentationsmuster beider Verbandsgruppen zu den Haltungsformen Weidegang und Anbindehaltung ergründet. Von Interesse ist dieser Vergleich, da im Rahmen öffentlich-medialer Kommunikation die Diskussionsfronten zwischen beiden Verbandsgruppen als verhärtet dargestellt werden. Die Analyse der Aussagen der qualitativen Interviewreihe dieser Studie erlaubt die begründete Annahme, dass beide Verbandsgruppen mit den Themenkomplexen Anbindehaltung und Weidehaltung in einem wissenschaftlich orientierten Kommunikationskontext differenziert umgehen. Eine klare Polarisierung der Einstellungen zwischen beiden Verbandsgruppen war im Rahmen dieser Gesprächsformen nicht wahrnehmbar.
