If the label of Pennington Fast Acting Lime does not list a setting for your particular spreader, we recommend to calibrate your spreader as recommended on this video
Pennington Fast Acting Lime is used to fix low PH in the soil. That could not be likely the source of bad odor. If you have odor issue it could be bad soil , drainage problems, fungus, or animal excrement.
We would recommend spraying Pennington Fast Acting Lime at least 10 feet away from a well since it could contaminate the water.
We recommend following the specific product label instructions as the rates and instructions are based of research and testing from the manufacturer.
Pennington Fast Acting Lime is not going to provide alot of coverage to treat one acre so you will need multiple bags and should apply atleast once in the fall, once in the winter and once in the spring. Periodic pH readings of your soil should be done also to keep an eye on your pH levels.
Austinville Limestone Pelletized Dolomitic Limestone Pellets would be an alternative option even though may work a bit slower, would provide more coverage of the size area you are treating.
