LAWN FERTILIZERS
Garden Boom Once a Year
The longest-lasting fertiliser in the Garden Boom range allows for a single application per year, thereby ensuring a steady supply of nutrients to the lawn throughout the growing season. Nitrogen is released in line with the plants’ needs, depending on soil temperature and moisture levels, which minimises nutrient loss and nitrate pollution of groundwater.
It is best to apply the fertiliser in the spring, and it remains effective for 6 to 9 months.

Comparing the lawn growth if using fast-dissoluble fertilizers and long-term fertilizers

CRF technology – intelligent nutrient release

CRF (Controlled Release Fertiliser) technology utilises specially coated granules that ensure a gradual and controlled release of nutrients. The protective coating, made from organic materials, reacts to soil temperature, thereby adapting the supply of nutrients to the plants’ current needs throughout the growing season.
Unlike conventional fertilisers, which release most of their nutrients shortly after application, CRF technology supplies nitrogen continuously – precisely when the plants can make the best use of it. The result is more balanced nutrition, healthy growth and a long-lasting effect without unnecessary fluctuations.
At the same time, the gradual release significantly reduces nutrient leaching and losses through evaporation. As a result, fertilisation is more efficient, more environmentally friendly and maximises the benefit from every granule.

MU Technology – long-term nutrition the natural way

MU technology utilises urea-formaldehyde (ureaform), which ensures the long-term and uniform release of nitrogen without the use of a polymer coating.
The nitrogen is chemically bound in chains of varying lengths. Shorter chains become available to plants more quickly, whilst longer ones are gradually broken down by soil microorganisms. Plants thus receive nitrogen continuously, in line with the soil’s natural activity, for up to 10 months.
Unlike coated fertilisers, the release of nutrients here is not controlled by a polymer membrane, but by natural biological processes in the soil. The result is stable and long-term nutrition, more efficient use of nitrogen and a reduction in unwanted losses.

Properties of the Nutrients
Nitrogen - N
Nitrogen is a nutrient important to generally support the lawn growth. The supply of this nutrient is important for the lawn from the beginning of vegetation till the beginning of autumn. The application of a fertiliser having a higher nitrogen rate should be limited in the autumn period. Alternative fertilizers should be used for this period with reduced nitrogen levels.

Phosphorus - P
Phosphorus supports the growth and development of the grass-root system. Choosing a product with high phosphorus is important for the germination of newly sown seeds or the regenerating of lawns.

Potassium - K
Regularly supplying potassium gives a high resistance and tolerance of the lawn to stress conditions, e.g. high temperatures in summer. A higher potassium rate is very important also when preparing the lawn for winter, as it helps strengthen the cells of the plant. Pottasium is also important in root development.

Magnesium - MgO
It favourably influences the lawn colour and thus its aesthetical appearance and integrity.

What shall I know before starting using fertilizers…
Fertilizer class
The fertilizer application differs according to the seasons of the year – spring, summer, autumn fertilizers.
Fertilizer type
Long-lasting fertilizer is a good choice to have a top lawn.
Dosing fertilizer
Each fertilizer has got its pre-defined dose.
Granule sizer
The optimum granule-size is 1 - 4 mm.
Application period
The application time is ideally in the morning or evening hours because of the lawn temperature.
Soil conditions
Clayish soils have got other properties than sandy soils as for their permeability.
State of the lawn
A damaged lawn requires another nutrient ratio, generally changing the nitrogen and phosphorus ratio.
Number of applications
3 - 4 applications a year are enough when using long-lasting fertilizer.
Correct application
Your correct movement in the plot of land is important to minimise overdose.
Using a fertilizing plan
It’s a good advisor for whole-year maintenance.
Long-lasting fertilizer is a good choice to have a top lawn.
