Hey Jon. In places of transit of sheep and cattle, in roads, campgrounds, prairies, etc. the appearance of the batan or mint as a way of being is common. As you rightly say, it is due to the excrement and purines of livestock. These residues contain a great amount of nitrogen, and in areas where it accumulates, the veins of these two plants are frequent.
To lose it you have to remove the cattle, but since this is difficult, you have no choice but to cut and cut the plants. They both have solid roots in the subsoil that needs to be emptied. Cut and cut, remove the force and end slowly. Perform this cutting work at the time of the crescent moon to cause the greatest damage.
