(2024-01-18)In the recent decades, the German farmland marked faced enormous price increases. Those price increases caused intensive research. Among others, three streams of thought were especially in focus: farmland price ... -
Changing valuations of cultural ecosystem services along an urban-periurban gradient in Berlin
(2015-11-06)Urban green experiences high use-pressures through differing and conflicting demands. Eco-system services provided by urban green are manifold, with cultural ecosystem services (CES) representing socio-cultural benefits. ... -
Characterisation of genotypic and tissue specific resistance in oilseed rape (B. napus) against Sclerotinia sclerotiorum
(2020-01-03)Sclerotinia sclerotiorum is a necrotrophic ascomycete and the causal agent of stem rot disease, an economically important constraint in the cultivation of oilseed rape (Brassica napus L.). Since cultivar resistance is a ... -
Characterisation of organic cereals and grain legumes as feedstuffs for monogastric animals: Effects of variety and environmental conditions on the contents of crude nutrients, amino acids, thiamine, riboflavin, and in vitro digestibility of crude protein and amino acids
(2019-05-10)The sufficient supply of nutrients, in particular of protein and amino acids, for monogastric animals in organic farming is challenging. For one thing, some feedstuffs that are rich in crude protein and contain large ... -
