Enforce®
Slow release Methylene Urea and ISODUR®.
NPK complex fertiliser for sports turf and public green application with slow-release N sources ISODUR® and methylene urea.
- Long-life complete fertilizer for various applications
- High magnesium content for positive influence on chlorophyll and leaf green formation
- No excessive growth and cuttings
- Reliable slow nitrogen release over several months
- Promotes vital root growth, increases the resistance of the grasses
- Reduction of workload, application risk and nutrient losses due to leaching

Trial
Enforce®has been proven to increase sward density when trialled against a competitor product and control plots. Enforce® improves sward density by almost 10% over the competitor product and near 30% over the control plots.


Enforce® Basic 15-5-8
What
Enforce® Basic is a NPK complex fertiliser with ISODUR® and methylene urea slow-release nitrogen, potassium sulphate, magnesium and iron.
When
Enforce® Basic long-term nitrogen forms ensure turf effect for 8-10 weeks, high N efficiency and lead to uniform growth and colour. Each granule contains all nutrients and thus guarantees a very exact distribution of the main and secondary trace nutrients.
Where
The granule size of Enforce® Basic is very fine and uniform 0.5-3mm and is therefore ideal for high-quality sports turf surfaces, lawncare and winter sports on turf mown >6mm. Longevity of Enforce® Basic is 8-10 weeks (2 months)

Why
Enforce® Basic contains the long-term nitrogen forms isobutylidene diurea nitrogen (IBDU - ISODUR®) and MU nitrogen with high proportions of fraction II N (hot water soluble nitrogen). Particularly emphasised is the high magnesium content with the positive influence on chlorophyll formation, promoting vital root growth and increasing the resistance of the grasses.
Longevity | Granule size | Cutting height | Application rate | Bag coverage | Bags/ha |
2 months | 0.5-3mm | >6mm | 15-40g/m2 | 625-1,666m2 | 6-16 |

Enforce® High N 20-5-8
What
Enforce® High-N is a NPK complex fertiliser with ISODUR® and methylene urea slow-release nitrogen, potassium sulphate, magnesium and iron.
When
Enforce® High-N long-term nitrogen forms ensure turf effect for many weeks and is especially suitable for spring and summer fertilisation with a high N and iron leading to good growth and coloration. Each grain contains all nutrients and thus guarantees a very exact distribution of the main and secondary trace nutrients.
Where
The granule size of Enforce® High-N is very fine and uniform 0.5-3 mm and is therefore ideal for high-quality sports turf surfaces and high-quality sports turf surfaces, lawncare and winter sports on turf mown >6mm. Longevity of Enforce® High-N is 8-10 weeks (2 months).

Why
Enforce® High-N contains the long-term nitrogen forms isobutylidene diurea nitrogen (IBDU - ISODUR®) and MU nitrogen with high proportions of fraction II N (hot water soluble nitrogen). Particularly emphasised is the high magnesium content with the positive influence on chlorophyll formation, promoting vital root growth and increasing the resistance of the grasses.

Enforce® High K 8-6-18
What
Enforce® High-K is a NPK complex fertiliser with ISODUR® and methylene urea slow-release nitrogen, potassium sulphate, magnesium and iron.
When
The high potassium content increases the stability of turf , especially in the winter months, and is thus particularly suitable for autumn fertilisation. An application in summer ensures a good utilisation of water and reduces drought stress. Each grain contains all nutrients and thus guarantees a very exact distribution of the main and secondary trace nutrients.
Where
The granule size of Enforce® High-K is very fine and uniform 0.5-3mm and is therefore ideal for high-quality sports turf surfaces and high-quality sports turf surfaces, lawncare and winter sports on turf mown >6mm. Longevity of Enforce® High-K is 8-10 weeks (2 months).

2 months | 0.5-3mm | >6mm | 15-40g/m2 | 625-1,666m2 | 6-16 |

Application
Apply evenly, at an application rate of 15-40g/m2 avoiding overlapped or missed areas, using a suitable calibrated spreader. If no rain falls during the 24 hours after application, irrigate the treated area thoroughly. Do not apply in frosty weather or hot, dry conditions. We recommend using PrecisionPro to ensure perfect application.
