GP DUO-Line

Professionally maintained stadium turf

PROFESSIONAL LIQUID FERTILISERS

THE SPECIALIST 2-PHASE SYSTEM FOR BUNDESLIGA STADIUMS AND GOLF GREENS

52-WEEK PROGRAMME FOR STADIUM TURF

For intensively used stadium turf, we recommend alternating GP Control and GP Impulse weekly, each at 10 L/ha.

Alternating the products targets different physiological processes: regeneration and stress resistance alternate with growth, chlorophyll formation and intense green colour.

WEEK 1: GP CONTROL

Application rate: 10 L/ha.

Ingredients: 3% Ascophyllum nodosum seaweed extract, 10% P₂O₅ (phosphorus), 15% K₂O (potassium), 2% SiO₂ (silicon), 0.15% boron, 0.02% molybdenum, 5% free L-amino acids.

Aim: improve root activity, regeneration and stress stability, preparing turf for the next period of heavy use.

WEEK 2: GP IMPULSE

Application rate: 10 L/ha.

Ingredients: 15% total nitrogen (N), 3% MgO (magnesium), 0.80% Fe (iron), 0.40% Mn (manganese), 0.15% Zn (zinc).

Aim: vigorous vegetative growth, intense green colour, rapid regeneration and an even, dense sward.

BENEFITS

More intense, more uniform green colour;

A denser sward through continuous nitrogen supply and regeneration support;

Faster recovery after matches;

Improved stress tolerance;

Improved root activity;

More even growth by alternating growth-building and regeneration phases.

THE PRINCIPLE OF WEEKLY ALTERNATION

GP Control → regeneration & resilience.

GP Impulse → growth & green colour.

This creates a continuous 2-week system for professional stadium turf.

RECOMMENDATION

Mix 10 litres of GP Impulse or GP Control with 400 litres of water per application, applying the products alternately each week to 1 hectare.

The recommendation should first be validated on a representative trial area or under normal stadium operating conditions. The final annual strategy should then be refined using soil analysis, leaf/tissue analysis, clipping removal, irrigation and actual playing intensity. In particular, nitrogen and phosphate supply should not be maintained at maximum levels independently of existing nutrient status.
