ProNitro® Seed Technology for stronger germination and faster establishment

Read our customer testimonials on ProNitro HERE

ProNitro® treated seeds contain both fast and slow release nitrogen, encapsulated within a smooth outer coating for improved seed flow. This targeted controlled release nitrogen is partnered with DLF’s hydroactive
water management technology to focus on improving nutrient utilisation during the early stages of plant growth for each developing seedling.

ProNitro® coated seed germinates with strong root development. Because of improved nutrient utilisation, stronger germination and faster, more uniform, seed establishment the resulting
sward has upwards of 34% more plants and a 30% increase in root length! This is particularly important when overseeding into a competitive sward.

Its greater density helps to reduce invasion by Poa annua and broad leaved weeds and is more stress tolerant and more capable of tolerating intensive wear.

The coating contains nitrogen and wetting agent. With this combination you will ensure a much more efficient use of water, and you will get much stronger and faster establishment, because the wetting agent will lower the water surface tension.

With ProNitro® coated seed you get a dense sward with less weeds in no time.  ProNitro® is recommended for all types of playing surfaces. On golf greens and football pitches in low-fertility, sandy soils, ProNitro® provides stronger and faster establishment. Sport fields sown with ProNitro® become playable sooner, while sod/turf producers obtain an earlier product containing less Poa annua.

ProNitro® coated seeds germinates strongly with strong root development 

As the fertiliser is coated directly onto the seeds, the germinating and developing seedling receives the full benefit of the additional nutrition, not the surrounding plants. Enhanced water management improves moisture availability allowing roots and shoots to grow rapidly in the first stages of growth developing strong, vigorous plants. This is particularly important when overseeding into a competitive sward.


Coating contains 15% nitrogen in fast- and slow-acting forms

Although the concept of coating grass seed with fertiliser is not new, ProNitro® goes much further. It contains a combination of fast-acting and slow-releasing nitrogen that feeds the seed and seedling throughout the first crucial month. Tests show that the leaching of nitrogen is far less with ProNitro® than with regular grass seed and a standard fertiliser. With its 15% nitrogen content, ProNitro® is also far more effective. In comparison, the nitrogen content of existing seed coatings is typically between 1% and 2%, which is why the effects are often negligible.

Increase plant survival rates by up to 34%

Very little goes to waste with ProNitro® hydroactive. The nitrogen in the coating goes directly to your germinating seeds and developing seedlings. Roots and shoots grow rapidly in the first stages of growth; the seedlings become strong and vigorous and competitive to weeds. After establishement the fast growth wears off as the fertilizer is used up. Rapid growth improves the take-up of all available soil nutrients and decreases nutrient losses into the environment by fixation or leaching. This is especially relevant when overseeding a competitive sward.

Tests by the Sports Turf Research Institute show that grass establishes significantly better with coated grass seed. Up to 34% more plants survive the establishment phase, creating a denser sward. These plants also have more than 30% longer roots compared to untreated seeds, resulting in better stress-tolerance.
