octaedra on growth of Agropyron trachycaulum (Link) Malte, a grass species frequently occurring in Kananaskis Valley, was investigated at different watering regimes.
Seeds of the grass species Agropyron trachycaulum (slender wheatgrass) were sown 6 wk before the experiments were set up in a box containing peat (the seeds were kindly provided by Hannas Seeds Ltd., Lacombe, Alberta, Canada).
The growth of Agropyron trachycaulum was generally not significantly affected by the watering regime.
octaedra caused an increase in shoot biomass and tended to increase root biomass of Agropyron trachycaulum. In addition, the earthworms altered the resource allocation by A.
On 6-7 July 1990 seeds mixed with damp sand were broadcast in each 9 x 9 m plot from one of 60 individually measured and weighed bags of six grasses (Agropyron trachycaulum

Barnh., Rudbeckia hirta L., Solidago rigida L., Verbena hastata L., Zizia aurea).
