TABLE 7. Cover of plug-type Puccinellia transplants on three sampling 

 dates for six fertilizer treatments at Kerlavos; planted May 

 1979. 



a Cover of a plug at planting was ca. 2 5 cm 2 . 



k Standard error of difference among equally replicated fertilizer 

 treatment means: 48 for May 1980, 49 for September 1980, 107 for May 

 1981; n=10. Comparison of initial fertilizer treatments for May 1981 

 may not be entirely appropriate because of the refertilization. 



c Refertilized with Mag Amp + Osmocote 3 (2.8gN + 4.1 gP per 

 transplant) in September 1980 after data collection. 



d Source of P was concentrated superphosphate.
