Tiergerechtheit auf ökologischen Milchviehbetrieben
(Bio Austria, 2004)
Ziel des vorliegenden Forschungsvorhabens war, nähere Daten über die Tiergerechtheit in der Ökologischen Milchviehhaltung zu gewinnen. Die hier vorgestellten Ergebnisse sind Teil eines Forschungsvorhabens mit dem Titel „Ökologische Milch- und Rindfleischproduktion“, welches im Rahmen des Bundesprogramms Ökologischer Landbau durchgeführt wurde, gefördert durch die Bundesanstalt für Landwirtschaft und Ernährung (BLE), Bonn (HÖRNING et al. 2004). Dabei wurde ein zweistufiges Verfahren gewählt.

Effects of post-harvest treatments on the carbohydrate composition of yacon roots in the Peruvian Andes
(2004)
Yacon (Smallanthus sonchifolius [Poepp. & Endl.] H. Robinson) is an under-exploited native root crop of the Andes, which stores oligofructans (fructo-oligosaccharides, FOS) as its main component of dry matter (DM). FOS are of increasing economic interest because of their low caloric value in human diets and bifidogenic benefits on colon health. Two on-farm experiments were conducted to: (i) determine the effect of shaded, short-term storage at 1990 and 2930 m a.s.l. in the Andean highlands; and (ii) address the effects ...

Use of digital camera to assess nitrogen status of winter wheat in the Northern China Plain
(2004)
The most widely used methods to assess the nitrogen (N) status of winter wheat (Triticum aestivum L.) are the determination of plant total N by combustion, the testing of nitrate in the leaf tissue and the use of SPAD readings. However, due to their labor requirements or high costs these methods can hardly be applied to the huge wheat growing areas of the Northern China Plain. This study therefore examined an alternative method to measure the N status of wheat by using a digital camera to record the visible green ...

Settlement history of a mountain oasis in Northern Oman
(2004)
To unravel the settlement history of oases in northern Oman, data on topography, the agricultural setting, water and soil parameters and archaeological findings were collected in the Wadi Bani Awf with its head oasis Balad Seet. Data collection lasted from April 2000 to April 2003 and was based on the establishment of a 3D-georeferenced map of the oasis comprising all its major infrastructural and agronomic features. At today's Balad Seet, a total of 8.8 ha are planted to 2,800 date palms and 4.6 ha are divided into ...

Organic inputs and farmers' management strategies in millet fields of western Niger
(2004)
Research on soil fertility management in sub-Saharan Africa was criticized lately for largely ignoring farmers’ management strategies and the underlying principles. To fill this gap of knowledge, detailed interviews were conducted with 108 farm households about their rationale in managing the soil fertility of 307 individual fields in the agro-pastoral village territory of Chikal in western Niger. To amplify the farmers’ information on manuring and corralling practices, repeated measurements of applied amounts of ...
