Agriculture/farming

There is a wide range of different applications for calcium cyanamide in agriculture. In addition to its fertilizing effect calcium cyanamide, when used competently, can increase soil fertility and plants health. The proper use of calcium cyanamide is described below based on the examples of different crop cultures, along with a discussion of the application period and suggestions for the application rate for each crop example.

Grassland

Calcium cyanamide gets your horse pasture up to a steady trot!

Grazing is the most natural, the healthiest and the most affordable way to keep horses. However, horse pastures present problems that require careful pasture management.

And it is less about quantity than quality. Which is why successful horse breeders swear by calcium cyanamide:

  • Calcium cyanamide ensures an ideal composition of upper and lower grasses, clover and forage herbs, creating a dense, durable sod (sward) that makes for a tasty, mineral-rich, low-nitrate feed
  • Its lime content counteracts soil acidification

 

Recommended use

 

When to apply Application rate Important notes
When vegetation begins in the spring, when the forsythia blossoms start to appear 300 - 400 kg/ha The sod should be dry, but the soil moist
or
Repeat fertilization in July/August 300  kg/ha

The sod should be dry but the soil moist

 

Additional Information:

 

  • Once the fertilizing effect of the calcium cyanamide is starting to take hold – noticeable by the fact that the grass is starting to recover – the surfaces can be used for grazing again (about 2 to 3 weeks after fertilization)
  • Particularly opportune times to do this are in Spring from the beginning of March, and in late summer through to the beginning of September.

Vegetable cultivation

Calcium cyanamide fattens up the brassicas

  • The even and sustained supply of nitrogen ensures harmonious growth and promotes the formation of solid, high-quality heads. This also provides better storage stability
  • The high lime content counteracts the acidification and incrustation of the soil
  • The rotting of harvest residues is accelerated
  • Less problems with clubroot infestantion
    • Suppressing of resting spore germination and reduction of zoospore mobility in the soil (calcium!)
    • Hampering the root hair penetraton due to stronger cell walls (calcium!)
    • Compensation of clubroot damage by stronger root growth due to increased uptake of ammonium nitrogen
  • Strengthens the competitiveness of cultivated plants against weeds

 

Fertilizing clubroot infested areas

 

When to apply Application rate Important notes

2 weeks before sowing /planting and repeat if necessary

400 - 500 kg/ha Work into the soil with discs or a power harrow
or
2 to 3 weeks after sowing / planting 400 - 500 kg/ha* Only on well-established brassica plants or sown brassica 10 to 15 cm high, foliage must be dry (no dew!)

* with cauliflower not more than 300 kg/ha, with Chinese cabbage no top dressing

 

Fertilizing areas not infected with clubroot

 

When to apply Application rate Important notes
2 - 3 weeks after planting* 400 - 500 kg/ha Spread on dry plants but the soil should be moist

 

Additional Information:

 

  • Weeds are particularly sensitive starting from the germination stage through to the 4-leaf stage

Orcharding

Calcium cyanamide for top-quality orcharding

  • Calcium cyanamide ensures a sustained supply of nitrogen reaches the plant as and when needed, and by simultaneously supplying calcium improves fructification and shelf life of fruit
  • The even nitrogen supply of Calcium cyanamide ensures good woodiness resulting in better winter hardiness

 

Recommended use

 

Crop Application rate When to apply
Pome and stone fruits 250 - 350 kg/ha In the dormancy period, until shortly before the start of sprouting

 

Strawberries

 

Additional Information:

 

  • Spreading calcium cyanamide in the autumn on the fallen leaves accelerates their rotting
  • Calcium cyanamide increases the biological activity of the soil

Other applications

Calcium cyanamide helps raise them!

  • The form of nitrogen that is protected from leaching losses and the long-lasting N fertilizer effect together ensure a secure supply of nitrogen over a long period of time, even with early application
  • The high lime content prevents a decrease in the pH value of the soil
  • The biological activity of the soil is increased, and soil-borne pathogenic fungi are suppressed

 

Recommended use

 

New plants

 

When to apply Application rate Improtant notes
2 to 3 weeks before lining out the plants 300 - 500 kg/ha Work into the soil;
observe the waiting period

 

Existing plants

 

When to apply Application rate Important notes
End of February until the beginning of March 300 - 400 kg/ha Do not spread onto the leaves of sensitive tree species (risk of leaf burn)
