- What limestone rate is recommended for this pasture in tons per acre?
Limestone recommendations are shown in the .Limestone Suggestions. section of the soil
test report. The recommendation is reported as pounds of Effective Neutralizing Material (ENM)
needed per acre to raise the soil pHs to a desirable range for a particular crop. The limestone rate,
in tons per acre, recommended for that field is calculated by dividing the ENM recommendation
from the soil test report by the ENM guarantee of the limestone dealer. For example, if the ENM
recommendation from the soil test report is 1600 lbs. and the limestone dealer guarantees 400 lbs.
per ton of agricultural limestone, the amount of limestone that should be spread per acre is 4 tons
(1600/400 = 4 tons limestone per acre).
NOTE: The ENM value must be selected from the soil test report that corresponds to
the desired crop.
