GP 3D-Wasserspeicher is a professional wetting agent, a molecular soil drainage preparation based on innovative copolymer 3D water-storage technology. It uses active surfactants that create a three-dimensional, multimolecular water-storage structure in the soil. As a result, water from rainfall and irrigation does not run off the surface or evaporate unused: it penetrates the soil profile completely and remains available to the root system.

The preparation eliminates soil hydrophobicity and LDS (Localised Dry Spots). It provides real water savings of up to 35%, reduces irrigation frequency and maintains stable water availability in the root zone for up to 5 months after a single application. It biodegrades and is free from microplastics.

Designed for professional care of sports turf, golf courses, municipal green spaces, trees, shrubs and ornamental plants.

GP 3D-Wasserspeicher belongs to the class of professional wetting agents: molecular soil surfactants that modify soil physical properties at the level of water surface tension.

Wetting agents fundamentally work by reducing water surface tension where it contacts soil particles. In healthy, absorbent soil, water naturally enters the profile and fills spaces between mineral particles. However, prolonged drought, high temperatures, accumulated organic matter and mechanical compaction cause intensively used turf to develop soil hydrophobicity.

Hydrophobicity means that soil loses its ability to absorb water. Rainfall or irrigation does not enter the profile: it runs off, collects in depressions or evaporates unused. This produces LDS, irregular brown patches where roots suffer water shortage despite regular irrigation.

Soil hydrophobicity affects golf courses, particularly greens on sandy substrates; intensively used sports pitches; turf exposed to high summer temperatures; and urban green spaces in regions with limited water resources.

After application, the active copolymer molecules enter the soil profile and produce four simultaneous effects:

1. Reduced water surface tension. Surfactants modify surface tension at the interface between water and soil particles, allowing water into previously hydrophobic areas. Water from rainfall and irrigation penetrates the soil profile completely rather than running off or evaporating unused.

2. Three-dimensional water-storage structure. The multimolecular copolymer structure distributes water vertically and horizontally throughout the root zone. Water remains available to roots several times longer than in non-activated soil.

3. Removal of waterlogging and drainage action. Excess water is distributed efficiently through the profile instead of stagnating on the surface, eliminating waterlogging and puddles and reducing conditions favourable to fungal diseases.

4. Improved fertilisation efficiency. Complete water penetration allows plants to take up 100% of the nutrients from fertilisers. The preparation reduces macro- and micronutrient leaching and increases the economic efficiency of fertilisation programmes.

The liquid preparation is available in four pack sizes matched to site size and care-programme intensity:

All packs contain the same liquid preparation at the same concentration. Pack choice depends solely on site size and storage logistics.

Mix 20 litres of 3D-Wasserspeicher with 400 litres of water.

Reference coverage: the concentrated stock solution enables one application over 10,000 m² of turf.

After applying the stock solution, water in with 4–6 L/m². This activates the copolymer structure and allows its three-dimensional distribution in the soil profile.

Choose a pack size matching the site area and scope of the care programme.

Prepare the stock solution according to the manufacturer's instructions, matched to the treatment area and plant type: turf, trees or ornamentals.

Apply using a large-area sprayer for turf or targeted irrigation for trees and shrubs.

Apply evenly, avoiding overlaps and local overdosing.

Activate with water: irrigate with 4–6 L/m² after application to activate the copolymer structure in the soil profile.

Apply before or early in the growing season to maximise benefits throughout the period of high temperatures;

A single application acts for up to 5 months, so one treatment per season is sufficient in a professional programme;

In intensive programmes, application may be repeated in the annual cycle depending on soil type and operating conditions;

Do not apply to frozen soil or during heavy rain that could wash the preparation out before activation;

The preparation can be combined with GP Premium (CRF) and GP Sport (UF Premium) mineral fertilisation programmes. These technologies complement one another, and the wetting agent additionally increases nutrient uptake from fertilisers.

Apply at moderate temperatures to soils that retain water absorption capacity. Do not exceed recommended rates. The preparation is fully ecological and biodegradable, safe for the natural environment, groundwater and soil organisms.

Liquid GP 3D-Wasserspeicher is the third technological pillar of professional GreenPlan systems, complementing the fertilisation technologies:

GP Premium (CRF technology) → controlled nutrient release through a polymer coating;

GP Sport (UF Premium technology) → long-lasting, biologically regulated nitrogen release;

3D water-storage range → intelligent root-zone water management and wetting agent.

Together, these pillars form a complete system for professional care of sports turf and municipal green spaces. Each addresses a different agronomic dimension: nutritional precision (CRF), long-term action (UF) and water efficiency (3D).

GP 3D-Wasserspeicher is also available in granular form as a component of GP Rasendünger mit 3D-Wasserspeicher-Technologie (16 kg), combining mineral fertilisation and wetting-agent technology in one product.

What is a wetting agent, and why does professional turf need one? A wetting agent is a professional soil surfactant that reduces water surface tension where it contacts soil particles. Prolonged drought, high temperatures, organic matter accumulation and compaction cause soil hydrophobicity in intensively used turf: rainfall and irrigation run off instead of entering the profile. A wetting agent restores the soil's ability to absorb water and eliminates LDS.

What are LDS, and how does GP 3D-Wasserspeicher eliminate them? LDS (Localised Dry Spots) are irregular brown areas where soil has become hydrophobic and does not absorb water. Plants suffer water shortage even with regular irrigation. Active biopolymer surfactants restore the soil's absorption capacity and eliminate LDS throughout the soil profile.

How long does one application last? Up to 5 months. In a professional care programme, one treatment per season is sufficient to maintain stable water management and eliminate soil hydrophobicity throughout the period of high temperatures.

How much can water consumption actually be reduced? The preparation enables a real, measurable reduction of up to 35% in water consumption, alongside reduced irrigation frequency.

Is it environmentally safe? Yes. GP 3D-Wasserspeicher is 100% ecological, biodegradable and microplastic-free. It does not accumulate in the soil profile and is safe for the natural environment, groundwater and soil organisms. It is aligned with water-saving policy objectives and the European Green Deal.

Can it be used alongside mineral fertilisation? Yes, particularly effectively. It increases water penetration and nutrient uptake from fertilisers. Mineral components from GP Premium (CRF) or GP Sport (UF) are taken up completely, while their leaching into groundwater is reduced. This improves the economic efficiency of the fertilisation programme.

Does it help with fungal diseases? It is not a fungicide, but reduces conditions favourable to fungal diseases by removing waterlogging and puddles, reducing excessive surface moisture and improving soil-profile aeration. Its role is preventative rather than curative in relation to fungal disease.

Which pack should be chosen? Choose according to site size: 5 L for domestic lawns, smaller ornamental areas and targeted use on trees and shrubs; 20 L for medium-sized sites, municipal green spaces and compact training pitches; 200 L for full-size pitches, golf courses and larger green spaces; 1000 L (IBC) for large sites, sports complexes and centrally managed networks. Composition and concentration are identical across all pack sizes.

Is it also suitable for domestic lawns? Yes. It is effective in the care of representative, ornamental and domestic lawns, especially those exposed to dry periods or located in regions with limited access to water. It is particularly recommended for sandy, hydrophobic soils and visible LDS.

The 3D water-storage products provide water savings of up to 35%. As this is a pure water-storage preparation, it contains no fertiliser technologies.
