Grass species on the course — know your most important material
Materials · 8 min
Grass is the greenkeeper's most important material, and the species have widely different strengths. The article covers the main lawn grasses — red fescue, bentgrass, annual ryegrass, meadow fescue and annual ryegrass — their requirements for cutting, nutrition and water, and how you control the species composition with overseeding and care. The course's competence objectives require exactly that you can identify grass species and describe their requirements for growth and soil conditions.

IPM and pesticide rules on golf courses
Rules · 9 min
Golf courses are among the most regulated green areas in Denmark. The article explains IPM principles from the EU's pesticide directive, the golf regulation's load limits for four agent groups, the annual reporting in the Environmental Authority's Greendata, and the requirements for spraying certificate, MAB authorisation and spray log. It is knowledge you must be able to demonstrate both in your everyday work and at your journeyman's test.

Watering technique — from sensor to sprinkler
Technique · 8 min
Water is both the grass's lifeline and a scarce resource. The article reviews the watering account with precipitation and evaporation, measurement with soil moisture sensors, the structure of a modern watering system with pump station, sections and IT control as well as the principles for watering deeply, infrequently and early. The competence goals require that you can set up and maintain watering systems and design systems that optimize water consumption.

Aeration, top dressing, preparation for winter, leaf collection
Technique · 8 min
The most important care you don't see: the fight against thatch and compaction in the growing layer. The article explains what thatch does to a green and covers the mechanical maintenance methods from the education's turf care subject — scarification aeration deep aeration vertical cutting and top dressing — and why sand selection for top dressing is critical to avoid harmful layering.
→
Establishment of greens, tees, and bunkers
Technique · 9 min
To build a green is engineering at grass height. The article reviews the USGA method's layer structure with drain pipes gravel layer and approximately 30 cm sand-based growth layer requirements for surveying and staking principles for tees and bunkers and establishing the grass itself. Competence objectives require that you can design establish and reorganize hole sequences bunkers tees and greens.

Drones, sensors and data on the future course
Technique · 8 min
Greenkeeping has become a data profession. The article covers drones for mapping and documentation — including EU drone regulations and drone signs via the Road Authority — as well as sensors, robotic mowers, GPS-controlled equipment and measuring tools such as the speed meter. The competency goals require knowledge of the latest technology and measuring tools to analyse the course's playing quality and grass growth conditions.
