Over a period of 10 years the Bavarian State Research Center for Agriculture tested the effect of calcium cyanamide in potatoes. In 17 trials the effect of a fertilization with 400 kg/ha of calcium cyanamide was tested. The results showed, that in average approximately 5% of the potatoes did show less or no damage from wireworm infestations. The additionally marketable tubers payed off more than three times the additional costs incurred.
Comparable results were also achieved by DLR Rheinland-Pfalz (7 trials, 5 years). Here, calcium cyanamide Perlka® reduced wireworm infestation by an average of 29% compared with conventional fertilisation.
Calcium cyanamide is a very special fertilizer. It not only supplies the soil with nitrogen and lime but it also offers a range of other unique special effects. Many farmers insist on calcium cyanamide or PERLKA® in order to prevent yield and quality losses during increasingly tight crop rotations, or to be able to manage them properly once again. Why? – because soil hygiene is more important than ever to ensure sustainable production.
