| Abstract/Contents: | "In spring 1974 Weibulls Turf Grass Section received a soil sample for testing. It was heavily contaminated with couch grass rhizomes. The normal chemical analysis was made, but also a small investigation to learn what the rhizomes looked like. In a soil sample of 650 g, 51 pieces of rhizomes were found. The total weight and length of the The total weight and length of the rhizomes were 12 g and 382 cm resp. Out of 255 nodes only 42 were classified as dead. 55 nodes had even developed white - greenish shoots. These shoots could obviously give rise to a couch grass infestation immediately after preparing the seedbed. In most cases a minor infestation of couch grass will not cause big troubles. In a turf dominated by Festcua rubra L. and Agrosits tenuis Sibth. and kept at a low mowing height, the couch grass will disappear. On the other hand it might survive under high cut. Thanks to the well-developed underground organs the couch grass can compete better under insufficient moisture and nitrogen conditions, than the surrounding grass plants. This might disturb the general impression of the turf. Besides couch grass (Agropyron repens (L.) Beauv.) there are many other weeds propagated by underground organs, such as Achillea millefolium L., Circium arvense L., Sonchus arvensis L. and Taraxacum vulgare L. Some of the most important weeds spread by seeds are Matricaria inodora, Lapsana communis, Fumaria officinalis, Senecio vulgaris and Chenopodium album. There are good reasons to draw attention to the content of weeds in the top soil. The chemical soil analysis does not revel this. The soil analysis can give excellent results only from the physical and chemical point of view. At the same time the soil might show a low biological value because of weed infestation, as in the related case." show a low biological value because of weed infestation, as in the related case. |
