Phil, good to see you on here. We are having the same issues with high mag soils but coming up low on tissue test. I am going to start using novacrop for proper sap testing as they are the only in Europe that do it I believe. We are moving to use 38-0-0-19 UAS for all fertiliser applications now but going to buffer with molasses and probably humic, whilst adding mn and mg foliar in at the same time. Any thoughts on this from anyone?

On another note agrovista are starting to sell a ‘liquid gypsum’ product which I am not sure is a snake oil or not.
