as anyone used Perlka fertiliser to prevent club root in brassicas - grown on an allotment? If so, how easy was it to use the correct amount and take correct safety precautions?

Does it not come with instructions? I just use garden lime on the bed they're to be planting in and also grow them on form seedlings to plugs to 4"/10cms pots so they have a good root system before getting into the soil.

I'd not heard of the stuff before but looked at a couple of data sheets. It seems to be for agricultural use as rates are in Kg/acre
e.g. for cabbage
160-600Kg per acre
which works out to 40-150g per square metre applied 2 weeks before planting and optionally again 2 weeks after planting
There are warnings that the overall amount MUST NOT exceed the plant's requirement for nitrogen..
