Calcium cyanamide PERLKA®

for a healthy soil and healthy plants

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.

"Healthy soils mean healthy plants" goes the saying – and more than 100 years of calcium cyanamide production later this rule still hits the nail right on the head!

The following internet pages give detailed information about how calcium cyanamide works and how to use it for the best results.

 

What is calcium cyanamide?

Discovered more than 100 years ago, calcium cyanamide was the first mineral fertilizer to enable atmospheric nitrogen to be used for plant nutrition. Today the multipurpose fertilizer still plays an important role in crop cultivation, because calcium cyanamide is the only fertilizer that contains the nutrient element nitrogen in the so-called NCN binding form. This helps ensure that plants are supplied with nitrogen over a longer time period as and when needed.  Fertilizing with calcium cyanamide also increases the biological activity of the soil. Soil-borne pathogens are forced into retreat by the stronger natural competition.

The second nutrient element that calcium cyanamide contains is calcium. This is mostly water-soluble and so is immediately available to the plants. Whereas other nitrogen fertilizers tend to make the soil more acid, calcium cyanamide improves the lime balance of the soil. In sum, on soils that are fertilized with calcium cyanamide plants receive the ideal amount of nitrogen, the structure of the soil is improved through the addition of valuable lime, and the soil hygiene is improved at the same time.

For the main time of the year the grasses and the herbs growing on the pasture are the main source of food for grazing horses. Therefore it is very surprising that so many horse keepers neglect or completely ignore the care of the pasture. Many pastures are in such a bad condition, that one cannot have a quiet conscience when letting the horses grazing there: A poor quality of the forage inevitably affects the health of the horses. A well-considered pasture management can promote plants with...

Trostberg. This spring for the first time ever AlzChem is offering a double-nutrient fertilizer with nitrogen and phosphorus. The fertilizer, “PERLKA® NP Starter”, is made of calcium cyanamide and diammonium phosphate and features an optimized N/P ratio. It contains 18.9 % total nitrogen, 23 % P2O5 and 11 % CaO as water-soluble calcium. The phosphate is easily soluble and so is immediately available to the plants. The nitrogen occurs primarily as ammonium and cyanamide nitrogen. PERLKA®-NP...

Economic constraints mean crop farms today are mostly choosing to grow just a few crops. However, more frequent crop rotations allow the pathogens that cause certain plant diseases – harmful fungi, usually – to accumulate in the crop soil. Because these pathogens cannot be tackled in the soil directly the crops grown on them are increasingly contaminated with the diseases these pathogens cause, leading to reduced yields and serious economic losses. So naturally, crop cultivation experts are...
