Fertilization
• Spring 2002: ~ 3800 lbs/ac lime applied
• Spring 2003: ~ 4480 lbs/ac lime applied
• 2004: no lime applied– pH approaching 6.5 goal (up from ~5.7)

Summary of Results
• Soil tests: –Liming increased Ca levels and pH
• Forage Samples:–Legume percentage increased with
liming–Buttercup percentage decreased
with aeration• Transect data: insignificant• Cow counting data: insignificant
