Feeding the tobacco plant and protecting it against weeds is not a bad achievement. This is what some German biochemists have achieved. Herbicide is a cyanamide compound. This substance, in principle, is harmful to tobacco and therefore it is essential to find something that neutralizes it.

This neutralizer has been found, specifically in a microcanpinon of the pavement. Cyanamide is transformed into urea and amonic salts form from it. Ammonium salts are very rich foods for the plant.
