As anyone used this product yet if so how did you find it. It is supposed to be very good in the fight against clubroot .
Perlka composition
19.8% nitrogen (N)
50% lime (CaO)
1.5% magnesium (MgO)
Interesting. So its basically Fish Blood and Bone, Lime and egg shells.
sounds like a stealth liming thne.... clubroot hates lime......
Some very intresting reading about this product, if you google for Perlka see what you think
