Jarosite
 

Since 3 months ago I have been working in a jarosite depot in Spain as
assistant to Environmental Manager Dept. Our stock reach to 1000MTons up of
jarosite. I was checking its conductivity and effluents. My question to all
is if somebody is using or had been using this mineral to grow plants as
hydroponic system.

Thanks a lot
