“Consistent growth without peaks”

From public green to sports turf management
For nearly forty years, Lion van Logten has been working in public green maintenance. He started as a grounds worker and parks maintenance employee and advanced to coordinator and sports field manager for the Municipality of Heusden.
Today, he oversees more than 45 football pitches, plus several hockey, handball, and athletics facilities.

“We handle almost everything ourselves, except for major renovations and heavy maintenance.
I always say: I’d rather mow once more than have to sweep — it saves both time and money.”


Consistent growth with controlled release

Six years ago, Heusden switched to Mivena Controlled-Release Fertilizers (CRF), supplied by Vitagro.
Since then, the turf growth has become smoother and more predictable. While previous fertilizers caused visible peaks and dips, the CRF program ensures even, steady development throughout the season.

“With Mivena, the grass grows much more evenly.
It’s ten times better — maybe even fourteen.”


Mivena’s temperature-responsive coating follows the soil temperature. Nutrients are released only when the grass is actively growing, minimizing losses and keeping growth consistent — even through changing weather.


Smart seeding: strong base, fast recovery

Heusden deliberately opts for two grass species, each with its own role. During renovations we sow in two stages: first the smooth-stalked meadow grass, and after five mowing cycles we overseed with perennial ryegrass. The meadow grass forms a ‘concrete layer’ at the base of the turf: strong horizontal runners with deep roots that create a stable, firm foundation. The perennial ryegrass above it provides fast coverage, a fresh green colour and strong recovery after wear. Together they create a dense, durable turf that maintains its quality even under heavy use.

“Bluegrass holds the turf together; ryegrass fills up quickly and looks sharp.”

A proper starter fertilizer helps the turf close faster, minimizing weed pressure.
The result is a dense, resilient playing surface that stays strong even under heavy use.

“Deep, lateral rooting from bluegrass builds the load-bearing ‘foundation’; ryegrass finishes the surface for quick recovery and colour.”

This root structure explains why goal areas stay intact longer and recover faster. The stable lower layer spreads load, while the upper layer regrows quickly.

Heusden fertilization program (2023)

Each sports park is soil-tested and calculated individually.
Most fields receive four main applications per year, adapted to season and use intensity:

PeriodProductPurposeAvg. dose
March–AprilGranucote CRF 30-5-6+2MgO (3M)Spring base with CRF100–150 kg/ha
JuneGreenstar 22-9-9+2MgO (2–3M)Summer growth and color100–150 kg/ha

Additional field practice:
Coated seeds with fertilizer around them help reduce bird damage. This applies especially to renovated fields, as we sow the meadow grass on top of the soil and then work it in using a Cambridge roller, ensuring an even start. Where necessary, we make occasional nitrogen adjustments with the field sprayer.


Practical efficiency on the field

Heusden keeps the program compact and manageable for a small team. Four application moments per year are sufficient in most cases. Big bags of 500 kg keep the logistics light and safe. GPS-guided mowing robots at two clubs take over repetitive work and improve spreading accuracy by creating fixed driving lines. Thanks to the even nutrient release, growth peaks disappear, brushing is needed less often, and goal areas stay dense for longer.


Conclusion

What started as a search for less fluctuation and more control has become a proven system for consistent turf quality.
Heusden demonstrates that the right mix of controlled-release feeding, smart grass composition, and practical planning can truly make the difference.

Consistent growth — without peaks.
