Hello,
I would like to do some soil analysis: I mainly want to know the quantity of NPK ( nitrogen potassium phosphorus )
and boron, zinc, magnesium, calcium, in my soil.
I found some docs about soil analysis but I don't have the equipment required.
So I would like to know if you know some tests which could be done in a "standart" lab, I don't really care if I get approximate measures.
Thank you!
