Bogatin: It's exactly what you think it is and for the others it's chicken manure and no it's not too much.
Heh. And I though I was exaggerating with it. Lol. Thanks for this information.
When I prepare a native soil bed I throw something like 2kg per m2, when I prepare a hole I add 3,5kg per 100L of soil which would probably many of you take as a very high dosage, but this year I accidentaly added the double dosage (3,5kg to 50L or 15% of total soil) to 1 hole and the plant wasn't burned at all.
Again ... good shit to know. How long did you wait until transplanting a plant into that "over-fertilized" hole?
