This is a report of a six month project in the summer of 1995 at the Institute of Grassland and Environmental Research (IGER)/ North Wyke Station, Devon, Great Britain. The project is part of the fullfillment of a degree in biology at the University of Groningen (RUG, The Netherlands). To examine the effects of high nutrient input on seed viability, nylon mesh bags with seeds of selected semi-natural grassland species were buried on plots treated with N, P, K fertilizer at five sites in The Netherlands and Great Britain. Before burial a blank germination test in the laboratory took place. The fertilizing started in spring 1993 and will be repeated each year of the project. The seeds will be exhumed at each of four periods (year 1, 2, 4 and 8) and tested on their viability by means of germination. This year the first seed samples were exhumed and tested. The results show that there are no significant differences in viability of the seeds between the different treatments within the species of a site and between the treatments within the sites. However, there are significant differences in germination percentages between the blank germination test and the exhumed seeds. There are also significant differences between the species within the treatments and within the sites. Statistical analysis also shows significant differences in germination of the seeds of the same species and origin between the sites.
