GP SPORT • UF PREMIUM TECHNOLOGY

Professional balanced fertiliser with a complete trace-element complex for resilient turf

Short description: product section

GP Allround 16-7-16 is a professional fertiliser with a balanced, homogeneous NPK formulation enriched with a complete trace-element complex (B, Cu, Fe, Mn, Zn). Universally applicable throughout the growing season, it supplies resilient turf comprehensively with macro- and trace nutrients. UF technology (urea formaldehyde) releases nitrogen gradually and regulates availability evenly for up to 3 months.

The product is designed for professional care of sports pitches, golf courses and intensively used green spaces, as well as high-quality prestigious, ornamental and domestic lawns.

Key properties

Professional balanced fertiliser with homogeneous granule structure;

Complete trace-element complex: boron (B), copper (Cu), iron (Fe), manganese (Mn), zinc (Zn);

Balanced nitrogen-to-potassium ratio (16:16) for comprehensive nutrition in every season;

Nitrogen in UF technology (urea formaldehyde): regulated, gradual release;

Increased sulphur (10 % S) supports efficient nitrogen use;

Low in chloride, safe for sensitive sports grass species;

Effective for up to 3 months after a single application;

Granule size 1.0–3.15 mm for dust-free, precise spreading.

Universal fertiliser with a complete trace-element complex

GP Allround is for turf needing broad-spectrum nutrition, including NPK macronutrients and a complete trace-element complex essential for stable plant metabolism.

Balanced NPK 16-7-16 maintains equilibrium between above-ground growth (nitrogen) and mechanical resilience and stress tolerance (potassium). Phosphate (7 %) supports stable roots and efficient energy metabolism.

GP Allround's distinctive feature is its complete trace-element complex, often underestimated in turf agronomy:

Boron (B, 0.01 %): involved in carbohydrate transport and cell-wall synthesis;

Copper (Cu, 0.02 %): redox enzyme cofactor supporting lignification and stem strength;

Iron (Fe, 0.65 %): central to chlorophyll biosynthesis and deep turf colour;

Manganese (Mn, 0.01 %): activates photosynthetic enzymes;

Zinc (Zn, 0.02 %): participates in auxin synthesis and growth regulation.

Deficiency in any trace element causes metabolic disturbances visible only at advanced stages: chlorosis, reduced growth and declining resilience. GP Allround preventively covers all key trace-element requirements in a single application.

Three nitrogen forms, including UF technology (urea formaldehyde), supply turf evenly for up to 3 months.

Low chloride is important for sensitive sports grasses and turf on naturally saline soils.

How does UF technology work?

UF technology (urea formaldehyde), known in German as Formaldehydharnstoff, is an advanced nitrogen form with slow, controlled release.

Part of GP Allround's nitrogen (6 % N) is bound in long polymer chains synthesised from urea and formaldehyde. Soil bacteria and fungi gradually break these down, releasing plant-available nitrogen at a rate governed by microorganism activity and environmental conditions.

UF nitrogen in GP Allround includes two subfractions:

Cold-water-soluble nitrogen (CWS, 1.8 %): medium-speed availability;

Hot-water-soluble nitrogen (CWIN/HWIN, 4.2 %): long-term nitrogen reserve.

The high HWIN proportion provides particularly stable, long-term nutrition in the second half of the effective period, with no repeat application for up to 3 months.

Results of UF technology

Stable long-term turf nutrition for up to 3 months;

Even growth without surges;

Reduced nitrogen losses through leaching and emissions;

More efficient root nitrogen uptake;

Preventive coverage of trace-element requirements in one application;

Greater turf resistance to stress and fungal disease;

Predictable agronomic results throughout the effective period.

Applications

Fundamental turf maintenance during spring, summer and autumn;

Prevention of trace-element deficiency in professional programmes;

Fertilisation of sports and golf turf during intensive use;

High-quality football pitches, golf courses, prestigious, ornamental and utility turf.

GP Allround: application and parameters

Application rate and coverage (25 kg)

Application instructions

Calculate the area to be fertilised and measure the appropriate quantity of fertiliser at the chosen application rate.

Spread evenly on dry turf, preferably using a calibrated spreader.

Avoid overlapping spreading passes and locally exceeding the rate.

Water after application (2–4 mm) to initiate nutrient dissolution and movement into the root zone.

Good professional practice

Apply during active growth with stable soil temperature and sufficient moisture.

Do not apply during prolonged drought without irrigation, or to frozen or waterlogged soil.

On larger areas, two passes in a cross pattern are recommended to distribute the granules evenly.

In professional programmes, repeat every 10–12 weeks according to use intensity.

Application conditions

Do not apply during frost, drought or strong sunlight. Do not exceed the recommended rate. Contains iron and trace elements: avoid light-coloured surfaces (paving, façades, wood) because permanent staining may occur.

Declared composition

Role in the GP Sport programme

GP Allround is the universal element of the professional GP Sport programme:

New establishment / overseeding / turf laying → GP Starter: high phosphate, rooting, up to 6 weeks

Spring / summer / autumn → GP Klassik: universal seasonal fertiliser, colour, up to 3 months

All season → GP Allround: balanced NPK formulation + trace elements, up to 3 months

Summer / early autumn → GP NK: high potassium without phosphate, up to 3 months

Late autumn → GP Finale: highest potassium with magnesium, winter hardiness, up to 2 months

Frequently asked questions

When should GP Allround be applied? Throughout the growing season from spring to autumn. Particularly recommended to prevent trace-element deficiency or where soil analysis indicates shortages of boron, copper, iron, manganese or zinc.

How does it differ from GP Klassik? GP Klassik has more nitrogen (20 %), sulphur (9 %) and iron, optimised for intensive colour. GP Allround has more balanced NPK (16-7-16), all five trace elements and low chloride, for comprehensive nutrition and salinity-sensitive sites.

What do trace elements do? They participate in hundreds of enzymatic and metabolic processes. Deficiencies cause chlorosis, slower growth and reduced disease resistance. GP Allround covers boron, copper, iron, manganese and zinc requirements in one application.

How soon does it work? The first response is visible within days through immediately available ammonium nitrogen. Urea nitrogen is released over subsequent weeks and UF nitrogen over up to 3 months.

Does it contain chlorides? No, GP Allround is low in chloride, particularly important for sensitive sports grasses (Poa pratensis, Festuca rubra) and naturally saline soils.

Is it suitable for domestic lawns? Yes, especially lawns on trace-element-poor soils or where chlorosis, slow growth or increased fungal disease susceptibility indicate deficiencies.
