Abstract:
INTRODUCTION

Peat is the dominant growth medium used in ornamental potted plant production. However, in many areas of the world, including Denmark (Aaby, 1996), exploitation of peat bogs is restricted. Composts made from household or garden wastes may be attractive alternatives to peat. Such composts are, however, not uniform from time to time and may contain undesirable levels of salts, nutrients, and heavy metals (Grantzau, 1997). Therefore, commercial growers of pot plants are reluctant to use compost based on municipal waste or biowaste as growth medium.

In order to obtain a uniform, stable, and well defined final compost, Miscanthus straw was used as raw material in combination with different nitrogen sources. The purpose of this composting was to obtain defined products. These products were subsequently compared to peat-based growth media for potted plant production.
