Abstract—The active role of higher plants in the weathering of silicate minerals and rocks is still a question
for debate. The present work aimed at providing experimental evidence of the important role of a range of crop
plants in such processes. In order to quantitatively assess the possible effect of these diverse plant species on
the weathering of a basaltic rock, two laboratory experiments were carried out at room temperature. These compared the amounts of elements released from basalt when leached with a dilute salt solution in the ...
