Anaerobic digestion as a tool to eliminate animal parasites and weed seeds Organic Eprints
Johansen, Anders; Hansen, Christian M.; Andreasen, Christian; Carlsgart, Josefine; Nielsen, Henrik Bangsø; Roepstorff, Allan.
Anaerobic digestion of residual materials from animals and crops offers an opportunity to simultaneously produce bioenergy and plant fertilizers at single farms and in farm communities where input substrate materials and resulting digested residues are shared among member farms. A surplus benefit from this praxis may be the suppressing of propagules from harmful biological pest like animal parasites, pathogens, and weed seeds. In the BIOCONCENS project (http://www.icrofs.dk/Sider/Forskning/foejoIII_bioconcens.html) batch experiments were performed, where survival of six species of weeds and the pigs large roundworm Ascaris suum (non-embryonated eggs) was assessed under conditions similar to biogas plants managed at meso- (37°C) and thermophilic (50°C)...

Drought Tolerance and Perennial Weed Management Organic Eprints
Nkurunziza, Libère; Andreasen, Christian; Liu, Fulai; Streibig, Jens Carl.
The aim of this study was to investigate the effect of controlled soil water deficits on sprouting and shoot growth of Canada thistle, coltsfoots and quackgrass. A gradient of soil water contents was created by establishing different densities of barley. The plants were harvested 14 days after watering was stopped. On Canada thistle and coltsfoots, relative water content (RWC) in leaves was measured prior to harvest and biomass of all weed shoots were recorded at harvest. In terms of shoot biomass and leaf RWC quackgrass was drought tolerant while coltsfoot was drought sensitive and Canada thistle was between the two. The barley cover crop could have had a competitive effect upon the growth of the weeds; the effect, however, was not detrimental compared to...

Key perennial weeds in arable crops in the Nordic countries Organic Eprints
Salonen, Jukka; Andersson, Lars; Andreasen, Christian; Semb Torresen, Kirsten.
Our review on the most common perennial weeds in the Nordic countries draws on 1) a Nordic/Baltic joint desk-top study done in 1997-99, 2) information from national weed surveys and 3) expert opinions from Denmark, Finland, Norway and Sweden.

Survival of weed seeds and animal parasites as affected by anaerobic digestion at meso- and thermophilic conditions Organic Eprints
Johansen, Anders; Carlsgart, Josefine; Hansen, Christian M.; Roepstorff, Allan; Andreasen, Christian; Nielsen, Henrik Bangsø.
Anaerobic digestion of residual materials from animals and crops offers an opportunity to simultaneously produce bioenergy and plant fertilizers at single farms and in farm communities where input substrate materials and resulting digested residues are shared among member farms. A surplus benefit from this praxis may be the suppressing of propagules from harmful biological pests like weeds and animal pathogens (e.g. parasites). In the present work, batch experiments were performed, where survival of seed of seven species of weeds and non-embryonated eggs of the large roundworm of pigs, Ascaris suum, was assessed under conditions similar to biogas plants managed at meso- (37 °C) and thermophilic (55 °C) conditions. Cattle manure was used as digestion...

Tolerance of four spring barley (Hordeum vulgare L.) varieties to weed harrowing Organic Eprints
Hansen, Preben Klarskov; Rasmussen, Ilse A.; Holst, Niels; Andreasen, Christian.
We investigated the tolerance to weed harrowing of four spring barley varieties and examined the possible interactions between varietal weed suppressive ability and two nutrient levels. Tolerance was defined as the combined effect of crop resistance (ability to resist soil covering) and crop recovery (the ability to recover in terms of yield). The weed harrowing strategy was a combination of one pre- and one post-emergence weed harrowing. In terms of yield, the four varieties responded significantly differently to weed harrowing and the response depended on nutrient level. At the lower nutrient level, weed harrowing caused an increase in yield of 4.4 hkg ha-1 for a strong competitor (cv. Otira), while there was no effect on yield at the higher nutrient...

Tolerance to weed harrowing in four spring barley varieties Organic Eprints
Hansen, Preben Klarskov; Rasmussen, Ilse A.; Holst, Niels; Andreasen, Christian.
The aim of this study was to investigate possible interactions between a preventive and a curativ method (combination of one pre and one post-emergence weed harrowing). We estimated the damages by weed harrowing in four pure varieties of spring barley, and analysed if there were differences in resistance and tolerance to weed harrowing between the varieties. As organic growing conditions are characterised by greater differences in nutrient levels, we further examined if there was any interactions between harrowing resistance and tolerance of the varieties and two nutrient level. Tolerance to weed harrowing was measured as an immediate effect (Resistance=how much of the plant is covered with soil after weed harrowing), a short-term effect (growth rate...
