| By heating up carbohydrate-rich food, like cereals and potatoes, Acrylamide (AA), a probably carcinogen food ingredient, will be created due to a reaction of free Asparagine (Asn) and reducing sugar within the Maillard-Reaction. Up to now two opportunities to decrease AA are discussed. Firstly by changing technological food processing steps e.g. receipt modifications and secondly by plant production e.g. finding species and cultivars low in the content of precursors of AA. For cereals, free Asn is the limiting factor for formation of AA. By investigations of conventionally produced wheat-, spelt- and rye samples differences were found in the amount of Asn both in species and cultivars. It was assumed that these differences could also be found in... |

| In Deutschland werden im Ökologischen Landbau trotz vorhandener Nachfrage nach Speiseöl nur sehr wenige Ölpflanzen angebaut. Saflor oder Färberdistel ist dabei als eine sinnvolle Alternative zu Raps bzw. Sonnenblumen anzusehen, es liegen jedoch bislang nur wenige Untersuchungen zur Anbauwürdigkeit vor. 741 Saflorherkünfte wurden 2002 auf ihre Anbaueignung unter hiesigen Klimabedingungen zweiortig geprüft. 2003 wurden 65 daraus ausgelesene, überlegene Herkünfte in einer dreiortigen Leistungsprüfung getestet. Es zeigte sich neben einer sehr großen Variabilität des verwendeten Materials, dass sich vorrangig europäische Formen durch eine gute Kornausbildung und höhere Samenerträge auszeichneten. Zwischen beiden Jahren bestand keine Beziehung in den... |

| Acrylamide (AA) – probably carcinogen – is thermally created in carbohydrate-rich food (e. g. cereals) within the Maillard-Reaction by the reaction of asparagine and reducing sugars. First steps to decrease AA focused on changes in the technological food production process. However, these possibilities are limited due to occurring taste anomalies and consumer tolerance. Therefore, it might be an alternative to influence the precursors of AA. Up to now, multiple studies considering the influence of fertilisation, species, and cultivars on the content of asparagine (Asn) and reducing sugars have been carried out. But there is still a lack of information about the influence of the production system on the AA level. It can be expected that the amount of AA is... |

| A long-term experiment was established to examine the crop yield and the weed infestation, focussed on Canada thistle (Cirsium arvense), as effect of different intensity of primary tillage (mouldboard plough deep or shallow, double-layer plough, chisel plough) in combination with or without stubble tillage. The most effective ways to keep the infestation of C. arvense at a low level were deep mouldboard ploughing and the use of a double-layer plough. After the experiment had run seven years, the thistle biomass was < 2 g DM m-2 in these treatments, compared to 23–26 g DM m-2 in the treatments with chisel ploughing or shallow ploughing. In all treatments, stubble tillage in addition to primary tillage significantly reduced the thistle biomass by 30–80 %.... |

| Hedgerows are landscape features with ecological value and agricultural benefits which are appreciated in organic farming. Biomass from periodical cutting down of hedgerows is often unutilized litter. The study assesses different ways how to use wood chips from hedgerows, and quantifies the biomass potential for either mulching arable land with wood chips or, alternatively, for bioenergy use. The calculations are based on experiments at the experimental station for organic farming Kleinhohenheim and on literature. The yield of wood chips was clearly too low to mulch the total arable land of the model farm. Hedgerows on an area equal to 1% of the farm area yielded wood chips for 0.05 ha if 160 m3 ha-1 were applied. This layer significantly reduced weeds.... |
