Agrovista are pushing it as part of their inovations range, autumn application straight after harvest through the sprayer. I can't remember exactly what the claim was but supposed to be more effective than powdered gypsum in increasing flocculation.Tell me more about it please. Is this something you put through a sprayer like a trace element tonic at a litre or three/ha?
I'm looking at bulk solid gypsum to help balance high magnesium clays - that's a numbers game where achieving this goal means tens of tonnes/ha required. @l'ordinary bonville uses a lot of bulk gypsum from the same supplier as me.
Hmm. I can see a small benefit from some readily available calcium and sulphur but the calcium requirement to displace magnesium is a big quantity. Tonnes/ha not grammes/ha.Agrovista are pushing it as part of their inovations range, autumn application straight after harvest through the sprayer.

At what point, years or tons, do you think solid starts to make a difference?We started using liquid gypsum last year. About 5l/ha through the sprayer when applying glyphosate to stale seedbeds/covers etc.
Its effect should be more rapid than solid, hence i'm doing both for short term gain and longer term soil correction
10t/ha does not sound like a lot. I can see a difference where it was stockpiled here but that must have had a fair rate per hectare effectively.BTW 10t/ha does a grand job on heavy marsh clays by the Humber. We imported loads(grant aided) to rectify the 2013 Humber tidal inundation.
I can still find red lumps in mine when ploughing... my hope/theory is its still supplying sulphur, where they had the heaps its still very crumbly.Yes, the trioxide was awful. I walked some land that was for sale maybe ten years ago and you could still see lumps of it.
I spread some gypsum on the grass for the "double win". Best bit about the grass is you can take and spread at more cost effective times of the year.
