Evaluation of leaching tactics

Managing soil salts is a challenge wherever rainfall is limited and infrequent. That is why Patty Reedy and Bruce Williams, CGCS at Los Angeles Country Club took time several years ago to study leaching tactics to refine the process to a science. In their 2008 study on LACC's USGA spec, A4 bentgrass greens, they leached test greens for 3.75 hours and generated the following results:

- The reduction in salinity was the same (about 20%), whether the drains were left…
