I have a field with a high mg index (5.3) and moderate k (1.7) ph 6.1, it's fairly heavy land but last year it just didn't perform the grass was kinda yellowy and next to no yield compared to other fields. It was reseeded in 2011. now the yara rep tells me to put potash on ( he would) but I have for the last two years and it's done no use as far as I can see and was wondering if the mg would lock up the availability of k? Would gypsum bring down the mg?
Cheers
