Calcium cyanamide fertilizer against moss in the lawn - apply lime nitrogen: calcium

A lawn, on which large areas of moss form, usually destroys the decorative appearance of the entire garden. Therefore, nothing else helps here than to fight the moss permanently. Against this, lime nitrogen can be used, the blades of grass have then again the chance to grow on the entire surface and it creates a beautiful, green, continuous lawn carpet.

How does moss develop in the lawn?

Especially when the lawn is very shady and wet, shows the unpleasant moss. If it is not fought, it displaces the grasses over time and continues to spread. So the moss has a great advantage, especially on a weakened lawn, which is not exposed to the optimal conditions. It is important that the pH of the soil is adjusted so that the moss is no longer comfortable here. Especially when the soil is too acidic, the grasses are pushed back by the moss. Nursing mistakes, for example because the lawn was not scarified and thus too little air comes to the roots, can be the cause of a moss formation.

Advantages of calcium cyanamide

If lime nitrogen is used correctly, then it can be used to conjure up a beautiful, dense lawn in which the moss has no chance. For example, calcium cyanamide offers the following advantages in particular:
  • healthy soil
  • Spread of pathogens for diseases is prevented
  • is only gradually transformed into soil
  • is therefore available to the grass for a long time
  • Growth of grass is encouraged
  • Sward becomes denser and more durable
  • Moss is pushed back
  • other weeds can also be fought

The right time to strengthen and fertilize the lawn, especially to counteract the moss that has formed over the wet winter months, is the spring. A good preparation with the first grass clippings and a large area scarification should be given in any case. Otherwise, the day of fertilization should look like this:
  • Frost free
  • in frost, the fertilizer is not absorbed from the ground
  • dry
  • it rains, the grasses are wet too
  • however, this should be avoided
  • The soil should be moist, however
  • covered
  • Sunlight can also promote burning
Tip: Even if the lime nitrogen is to be spread on a slightly moist soil, the plants should not be moist. Therefore, it is recommended to wait one day for a rain to fertilize. Because then the soil is still sufficiently wet, but the grasses could already dry out again.

Calculate fertilizer quantity

To determine the correct amount for the existing lawn, the size must be determined. If you do not know the size of your lawn, you can take it in large steps in the transverse and longitudinal direction. For example, an expansive step of an adult is about one meter. To determine the square meter, then proceed as follows:
  • Count longitudinal steps
  • Count cross steps
  • multiply with each other
  • gives the total square meter area
  • multiply this by the amount of fertilizer per square meter
  • Information is given on the packaging
  • usually it is 20 g / m²
This results in the following example calculation:
5 meters long x 3 meters wide gives a surface area of ​​15 m². This is now multiplied by 20 and thus gives a total grammage of 300 g which is needed for the lawn area.
Tip: If no balance is available, there is a small trick to measuring the fertilizer. Either the appropriate amount of the packaging can be taken with the tablespoon. In this case, a heaped tablespoon corresponds to about 20 g of calcium cyanamide. For a measuring cup, 100 ml of measured calcium cyanamide weigh 100 g.

Procedure for fertilization

If the appropriate amount has been determined, then this is spread on the area. This works best with a spreader. Here, the lime nitrogen is added and then the area is driven row by row, the car evenly spreads the fertilizer on the lawn. If it is only a small area or if no spreader is available, then you should proceed as follows:
  • wear gloves
  • Put fertilizer in a bucket
  • always take a handful of fertilizer
  • to throw this out of the wrist
  • always diagonally upwards and forwards
  • so the little grains fly well apart
If the entire lawn has been fertilized, it must be kept well moist over the next few days. Otherwise, the fertilizer does not dissolve properly and can cause extensive burns in the lawn.
Tip: Lawns are ideally sprinkled twice.The second time should then be repeated one to two weeks after the first spread with the same amount of calcium cyanamide.

Use spreader correctly

If a spreading trolley is used, the correct dosage should be checked before fertilizing the lawn with lime nitrogen against moss. There is the following, very simple method:
  • Use the daily newspaper
  • Lay double side on the floor
  • corresponds to about 57 cm x 80 cm
  • almost half a square meter
  • Drive over the newspaper twice with the filled spreading trolley
The quantity of fertilizer that is now on this corresponds to the amount of calcium cyanite that the spreading trolley spreads over an area of ​​one square meter. This is above all also dependent on the respective spread of the spreader. Close the newspaper and measure or weigh the fertilizer on it. This avoids the spreader applying too much fertilizer.

Caution when using

Calcium cyanamide should only be applied with caution and care on the lawn. Because with an overdose or wrong application also the entire lawn and not only the moss contained therein can suffer. For if the lawn is overfertilized with calcium cyanide, then it comes here to significant burns. Even a young, newly sown grass does not tolerate this fertilization. It is better here to prevent moss formation prepare the lawn a few weeks before sowing accordingly. Therefore, the following should always be considered when using lime nitrogen:
  • work correctly
  • a lot does not always help a lot
  • do not exceed the recommended amount
  • apply evenly
  • Ideally use a spreading cart
Especially if pets or small children are in the household, they should not be in the vicinity during the scattering. The hobby gardener himself should always protect himself with rubber gloves when working with the highly concentrated mixture and make sure that nothing comes into the eyes. It is important to pay attention to the safety instructions of the manufacturer.
Tip: If no own spreader is available or should be purchased, these devices can be rented by the day in a well-stocked garden trade.

Avoidable errors

If burns appear on the lawn after fertilizing, then this is mainly due to avoidable mistakes. Thus, the burns can have the following causes:
  • Overdose
  • Never apply more than 30 g / m² of calcium cyanamide
  • Distribution unevenly
  • pay attention to overlaps in scatterers
  • On wet grass, grains stick to the blades of grass
  • newly sown lawn area
  • never fertilize in the first year of sowing
If a lawn has been burned by calcium cyanide, then it is not sure if it will recover. This depends mainly on the degree of burns. The lawn should now be kept moist and must not dry out. Normally, the grasses recover from the rhizome. If there is no recovery after about four weeks, the lawn will no longer recover at these points and it will have to be sown again.
