Bull, only use gypsum if the soil calcium levels are low and the ph is high. If the ph is low then lime is a better choice for the calcium. Raising the calcium levels in the soil will help relief compaction somewhat but dont expect a full cure. Adding gypsum will make the ground more fluid and as a result the other neccesary nutrients will leach faster and the boundup harmful elements that are present in the soil will be released and can damage the turf.
