GP Rabio

GP Rabio • Organic turf fertiliser 9-3-6

ORGANIC LINE • 100 % NATURAL • LONG-LASTING EFFECT

Professional organic turf fertiliser: pure nature at the full agronomic rate

Short description

GP Rabio is a professional, 100 % natural organic fertiliser for all types of turf, from domestic lawns to recreational and prestigious sites. The high concentration of organic matter (73.2 %), combined with a complete NPK 9-3-6 profile enriched with sulphur and sodium, simultaneously nourishes the sward and biologically regenerates the soil.

The product works through gradual mineralisation of organic matter by soil microorganisms. Nutrients are released at a rate corresponding to soil biological activity and the physiological needs of the turf. The effect lasts up to 12 weeks after a single application, without the risk of turf scorch or sudden growth surges.

The product is 100 % safe for children, pets and the natural environment. It contains no synthetic ingredients or microplastics. It comes as dust-free, easy-to-spread granules compatible with professional rotary and drop spreaders.

Role in the turf maintenance programme

Within a professional maintenance programme, GP Rabio acts as a base regenerative and nourishing fertiliser. Unlike mineral fertilisers that supply nutrients alone, GP Rabio works on two levels: it feeds the sward while rebuilding the soil as a living ecosystem.

The high organic matter content (73.2 %) directly feeds soil microorganisms, including bacteria, fungi and microfauna responsible for forming stable humus. Humus acts as a natural store of water and nutrients, improving soil cation exchange capacity (CEC) and resistance to drought stress and high temperatures.

Sulphur (3.7 % S, of which 3.2 % is water-soluble) supports efficient nitrogen use and synthesis of sulphur-containing amino acids (methionine, cysteine), which influence turf grass structural protein quality and colour intensity. Sodium (1.5 % Na) regulates the osmotic balance of plant cells and strengthens sward elasticity under use pressure.

Mode of action: biological nutrient mineralisation

In mineral fertilisation technologies, nutrients become available to the plant immediately after the granules dissolve. In organic fertilisers such as GP Rabio, nutrients remain bound within the organic matter matrix and are gradually released through mineralisation by soil microorganisms.

This mechanism provides three key agronomic benefits:

Synchronisation with plant demand: microorganisms are active under the same temperature and moisture conditions in which grass grows, releasing nutrients precisely when they are needed.

No risk of over-fertilisation: nutrients do not accumulate in the soil solution, eliminating the risk of turf scorch and leaching losses into groundwater.

Long-lasting nutrition: the complete mineralisation cycle ensures stable turf nutrition for up to 12 weeks.

Applications

Domestic and prestigious ornamental lawns;

Sports turf with moderate use intensity;

Recreational areas, parks and urban green spaces;

Humus-poor soils requiring biological regeneration;

Turf following intensive mineral fertilisation programmes (ecosystem regeneration function);

Maintenance programmes consistent with ecological standards and European Green Deal requirements.

Technical data

Declared composition

Application rate and programme

Standard rate: 50 g/m² (guide: 1 handful ≈ 30 g). Starting rate (first application): 100 g/m².

Three-application programme during the growing season:

Application I (late March / early April): starting rate 100 g/m². Role: activating soil microflora after winter and supplying the full nutrient profile at the start of growth.

Application II (late May / early June): standard rate 50 g/m². Role: maintaining nutrient supply during intensive growth.

Application III (late September / early October): standard rate 50 g/m². Role: preparing the sward for winter and building reserves in the root zone.

Application instructions

Spread the fertiliser evenly on dry turf, preferably the day after mowing.

Mechanical application (rotary or drop spreader) is preferred; when applying manually, use a cross pattern with two perpendicular passes.

Avoid application on hot days (>25 °C) or in strong winds.

Immediately after application, water thoroughly (at least 5–8 L/m²) unless rain is forecast within the next 24 hours.

The turf can be used normally on the day of application.

Good professional practice

GP Rabio can be combined with 3D water storage technology. After fertiliser application and watering, applying Save Water (granular or liquid) followed by the UV protection product Sonnenschutz is recommended.

In a hybrid organic-mineral programme, GP Rabio can alternate with GP Premium (CRF) or GP Sport (UF Premium) fertilisers. The organic component rebuilds the soil ecosystem while mineral precision ensures a rapid sward response.

Optimum conditions: soil temperature ≥ 8 °C at a depth of 0–10 cm; soil moist but not frozen.

Frequently asked questions

How does GP Rabio differ from a conventional mineral fertiliser? GP Rabio supplies both nutrients (NPK 9-3-6 + S + Na) and an organic substrate (73.2 %) that builds soil humus. A mineral fertiliser feeds only the plant; GP Rabio feeds the plant and regenerates the soil as a living ecosystem.

How long does one application last? Up to 12 weeks. Nutrients are released through biological mineralisation by soil microorganisms, so the rate of supply is synchronised with soil biological activity and turf demand.

Can GP Rabio scorch the sward? No. The high organic matter content and biological release mechanism rule out the risk of osmotic shock. The product is safe even if the reference rate is slightly exceeded.

Is the fertiliser safe for children and pets? Yes. GP Rabio is 100 % natural, free from synthetic ingredients and microplastics. Turf can be used normally on the day of application.

Can GP Rabio be combined with mineral fertilisation? Yes, this is a recommended strategy in Premium programmes. GP Rabio regenerates the soil, while CRF (GP Premium) or UF (GP Sport) fertilisers ensure precise, long-term nitrogen release. The technologies complement each other.

When is the first effect visible? Initial improvements in colour and sward density generally appear 10–14 days after application. The full agronomic effect, including improved soil structure, is visible after 4–6 weeks.

Is GP Rabio suitable for sandy soils? Yes, it is particularly recommended. Light sandy soils typically lack humus and lose water and nutrients quickly. GP Rabio's high organic matter concentration builds the soil's exchange complex and improves water retention.

Does GP Rabio have a smell? The product has a subtle, natural smell of plant-based organic matter that fades within 24–48 hours after application, particularly after watering the turf.
