Calcium cyanamide – so that your soil remains fertile
A long-term study carried out over 53 years by the Institute of Plant Nutrition at the Technical University Munich-Weihenstephan showed very clearly that using calcium cyanamide regularly resulted in a considerable increase in enzyme activity in the soil. This is regarded as a measure of the biological activity of the soil. Soil fertility is therefore significantly increased by the regular use of calcium cyanamide.
As the following graph shows, virtually all activity parameters are at their maximum in soils fertilized with calcium cyanamide.
