Calcium cyanamide – providing an even and sustained supply of nitrogen to your plants
The nitrogen bound in the calcium cyanamide is not directly available to the plants.
Ammonium (NH4), which can be taken up by plants directly through the roots, is only produced when the fertilizer is converted in the soil. With calcium cyanamide the further conversion of ammonium into nitrate nitrogen (=nitrification) is delayed (= inhibition of nitrification). This means that fertilizing with calcium cyanamide ensures that the crop is supplied with a nitrogen nutrient that has a strong ammonium emphasis and which is physiologically beneficial to the plants.
Unlike nitrate, which is easily movable in the soil solution, ammonium is bound to soil colloids (clay minerals). Therefore ammonium is not washed out, even during heavy precipitation, and can be absorbed by the plants gradually.
The gradual release of ammonium nitrogen from calcium cyanamide and the inhibition of nitrification cause the nitrogen to be evenly supplied to the plants over a long period of time. The result is a harmonious and healthy growth of the crop.
