METHODS AND MATERIALS 



Renovation methods 



Conventional establishment involved plowing, discing several times, 

 rock removal, firming of seedbed and seeding with a Brillion seeder. Sod 

 seeding involved the use of a John Deere Powrtill drill, equipped with 

 powered coulters which tilled a one-half inch wide strip every 8 inches. 

 There were no tillage operations preceding sod seedings. The herbicide 

 used depended on the sod species present. At all sites the grass was 

 mowed so that a maximum growth of four inches was present at seeding. 



Since legumes were seeded in all the studies, no nitrogen was applied 

 before or after seeding, except in Experiment 1, in which nitrogen was 

 applied, along with other fertilizer elements at various rates. To avoid 

 insect damage to new seedlings, Furadan lOG was broadcast at 10 lbs/acre 

 on all plots following seeding. 



Table 1 shows the soil and vegetative characteristics of the sites used 

 in the study. Seedings were made in 1976-77 at the Agricultural Experiment 

 Station, Kingman Farm, Madbury, N. H. 



Red clover establishment 

 This experiment was on a Buxton silt loam (Site No. 1, Table 1). It is 

 characterized as a deep soil with layers of clay in the profile which impede 

 vertical water movement and create seasonally high water tables, averaging 16 

 inches from the surface. Because of high water retention, the soil is prone 

 to heaving and legumes such as alfalfa have poor survival.
