First of all I orserved two plum trees and I realized that difference. That is project for my own. I observed the other plum trees around many buildings in a certain area. the climate or the other effects are equal but the only difference is soil. Around the carpenter's shops there is "dust"...
Hi everybody,
I am searching for a project and I need help.
Last year I realized that the trees which are around carpenters shops' have bigger fruits than the others.
I am searching about it. Can the Iron which comes from waste neils and screws affect the soil's mineral ratios?
How can they...
