Die Bedeutung der CO2-Fixierung von Leguminosenknöllchen für ihre Aktivität und Effizienz
(2009-10-09)The present work reports results from experiments on the influence of CO2 fixation for the N2 fixation in root nodules of legumes (Pisum sativum L. and Medicago sativa L.). It was shown ... -
Die Bedeutung der Landschaftsstruktur für die Bienendiversität und Bestäubung auf unterschiedlichen räumlichen Skalen
(2004-08-25)Pollination is one of the most important processes in terrestrial ecosystems. This free nature service depends on a homogeneous distribution and sufficient density of flower-visiting insects, ... -
Bee pollination of strawberries on different spatial scales – from crop varieties and fields to landscapes
(2013-03-06)The global majority of our crops is dependent on pollination. Hence, pollination contributes to one third of global crop production and is an ecosystem service of high commercial and social importance. Bees are the most ... -
Bees and wasps in agricultural landscapes: effects of dispersal corridors and land-use intensity at multiple spatial scales
(2006-08-04)Agricultural landscapes are characterized by close interactions between annually ploughed crop fields and relatively little disturbed noncrop areas. Many species have adapted to these mosaic ... -
Behaviour and performance of growing and finishing pigs depending on different housing conditions and sire breeds
(2022-10-11)Conventional pig farmers and more particularly their pigs face many challenges throughout different production stages that can alter the welfare and health of the animals and impair the farmers economy and motivation ... -
Beitrag von Ackerbohne (Vicia faba L.), Luzerne (Medicago sativa L.) und Saatwicke (Vicia sativa L.) zur Selbstregelung der N-Zufuhr in leguminosenbasierten Fruchtfolgen.
(2005-03-02)The contributions of faba bean, alfalfa and vetch as sole crops (M) and intercropped (I) with oat, orchard grass and annual ryegrass to the self-regulation of N input in legume-based cropping ... -
Beitrag zur Ermittlung der biochemischen Ursachen der Schwarzfleckigkeit bei Kartoffeln
(2007-10-23)Blackspot in potato tubers occurs after mechanical damage of the tubers during harvest, transportation and storage. The particularity of this qualtiy problem is a gradual discolouration of ... -
Beiträge zur Berücksichtigung des Eigenwertes von Tieren im Rahmen wohlfahrtsökonomischer Analysen
(2018-05-28)Nature can be valued in various ways. In the comprehension of the total value of nature two common approaches for the assessment of nature can be distinguished. Environmental economic analyzes are based on an anthropocentric ... -
Beiträge zur ernährungsphysiologischen Bewertung optimaler Methionin:Cystein Relationen in der Masthähnchenernährung unter besonderer Beachtung hoher Mischungsanteile von Insektenmehlen als alternative Eiweißquelle für Sojaprotein
(2019-06-04)Literature data on the optimal supply of growing meat-type chickens with the sulfur containing amino acids (SAA) show significant variations. Due to the close metabolic link of methionine (Met) and cysteine (Cys), the ... -
Beteiligung systemischer Signale an der Symptomauslösung bei Brassica napus nach Infektion mit Verticillium longisporum und V. dahliae
(2009-04-03)The main objective of this work was to study the induction of premature ripening and the appearance of stunting in the interaction between V. longisporum/B. napus by xylemsap-assumed signaling ... -
Bewertung von Tierwohlindikatoren für Mastschweine
(2024-08-05)The welfare of farm animals is a subject of controversial debate in the economy, politics, society and science. Methods for the assessment of animal welfare are an important component in objectifying the discussion. With ... -
Beyond the Blemishes
(2023-11-09)A significant amount of food produced worldwide is lost and wasted along the supply chain. The Food and Agriculture Organization of the United Nations (FAO) estimates that approximately 13 % of food is lost between harvest ... -
