I just got the results of my soil test back today and everything was pretty much where it needed to be except the potassium (k) level. The potassium level was under the proper level. I don't have an applicators licence but this is just for my yard and not for any of my lawn customers. I would like to know if I would be able to get a granular fertilizer with enough potassium to start raising the level. BTW in my county nitrogen is now illegal to put on your lawn unless you have low levels, but I have more than enough. So if anyone has any ideas they would be greatly appreciated. Thanks.
