One of my soil science books suggests the following for finely ground
limestone:
(pounds per 1,000 sq ft.)
Northern and central states:
sands and loamy sands-30
sandy loams-55
loams-85
silt loams-105
clay loams-120
muck-225
Sothern Coastal States:
sands and loamy sands-20
sandy loams-35
loams-50
silt loams-75
clay loams-100
muck-200
It takes about 6 months for lime to appreciably increase soil pH, and soils
will have to be relimed every 2-5 years due to the natural acidifying effects
of biological respiration,organic matter mineralization and precipitation.
Hope this helps
