will a pasture slitter be as effective as subsoiling sandy soils under grass to relieve compaction or are there better tools for loosening these light soils?
Unlikely as sandy soils compact naturally and often form pans. It is important to dig a hole and find the problem. If a pan/ tight layer is found that restrcts rooting and drainage then it needs to be broken with sub-soiling mnimising gamage to the sward above. A slitter is only going to slit surface compact and aerate the turf zone.
