[RAF]

Fields are high in mag and locking P&K up , what would be best product ? Calcifert is cheaper although is it a one year wonder ? Anyone used either ?

Calcifert Sulphur cheaper than gypsum?

 

[PSQ]

IF you need lime, use bulk calcium *ground* lime.

Calcifert is exactly the same, just prilled, and 6 times the price

If you don’t need to adjust pH, gypsum is usually free ex yard.

Calcifert S doesn't even claim to change pH, just supply Ca and Sulphur. The advantage of Calcifert S over Gypsum is that you can spread it to 24m through a normal spinner easily enough.

There is a 'Calcifert S' ?!

Go on, how much are they charging for something everyone else is giving away for free?

 

[NH 200]

Calcifert S is a good source of calcium with the added benefit of sulphur which can be accurately and easily applied, it can hardly be compared to recycled plasterboard as suggested above which sometimes contains high levels of heavy metals and unknown foreign objects hence the reason for it being classed as a waste product

I can’t remember what it was when I had some a couple of years ago, but £160/t rings a bell. At application rates of c.90 kg/ha and put on with a normal fert spreader, it’s hardly dearer than getting a contractor in with a belt spreader to spread this ‘free’ product (I assume that’s delivered free as well?).

40 mile haul, at a guess £6 or 7 tonne, spreading £4 to 4.50.

All in, £11.50 'ish, so about 1/14th of the cost. Or a 28T wagon load applied for about the same cost as 2T of 'Calcifert S' delivered but not spread.

I doubt 90kg/ha will do much. The first time we spread it here was at 2.5t/ha, and soil sampling 12 months later revealed no additional residual sulphur for the following crop compared to a control plot.

You won’t ever get residual sulphur, whatever form you apply Calcium Sulphate as, it leaches out, hence needing Sulphur annually (at least). The 90kg/ha rate was to apply the Sulphur requirement for a crop of Spring Barley, rather than a whole heap of Calcium.
