Behind every well-kept golf course is a greenkeeping team using more technology than most golfers realise. Soil sensors tell them exactly how much water greens need, GPS guides sprayers, drones spot stressed turf from above and robotic mowers cut fairways overnight. This technology helps courses play better, saves water and chemicals, and makes maintenance more sustainable. Here's a look at the main tools.
Soil moisture sensors
Handheld and buried sensors measure moisture, temperature and salinity in the root zone. Greenkeepers use the readings to water only where and when it's needed, which keeps greens firm and saves water.
Smart irrigation
Modern irrigation systems control individual sprinkler heads, adjust watering by weather and soil data, and can be operated from a phone or tablet. This avoids over-watering low areas and under-watering exposed slopes.
GPS sprayers and precision application
GPS-guided sprayers track exactly where products have been applied, avoid overlaps and switch off nozzles at the edges of greens and fairways. This reduces the amount of fertiliser and plant protection products used.
Robotic mowers
Autonomous mowers, similar to robotic lawnmowers but larger, can cut fairways, roughs and practice ranges, often at night. Benefits include:
- Lower fuel use and emissions with electric models.
- Quieter operation.
- Staff freed for skilled tasks such as green care.
Drones and imaging
Drones and sensors that measure plant health (such as multispectral imaging) can spot turf stress, disease or drainage problems early. Images also help plan projects such as tree work or bunker renovation. Read why golf courses remove trees.
Weather stations
On-site weather stations measure rainfall, temperature, humidity, wind and evaporation. Greenkeepers use the data to decide on watering, mowing and disease prevention. Read weather forecasts for golfers.
Green speed and firmness measurement
Greenkeepers measure green speed with a simple ramp that releases a ball at a set speed, and use firmness meters to check consistency. Daily data helps keep greens consistent from hole to hole. Read putting on fast and slow greens.
Course management software
Software tracks staff schedules, equipment maintenance, product use and budgets, helping clubs run maintenance efficiently and report on sustainability.
What it means for golfers
- More consistent conditions day to day.
- Firmer, healthier turf from better watering.
- Fewer disruptions from maintenance during play.
- More sustainable courses that protect wildlife and resources. Read golf courses and wildlife.

Frequently asked questions
Do robotic mowers cut greens?
Most robotic mowers currently cut fairways, rough and practice areas; greens are usually mown by skilled staff.
How does technology save water on golf courses?
Moisture sensors and smart irrigation deliver only the water each area needs.
How is green speed measured?
With a simple ramp: a ball is rolled down it onto the green, and the distance it travels gives the speed.
The bottom line
Technology helps greenkeepers produce better, more consistent courses while using fewer resources. From soil sensors to drones and robotic mowers, these tools are shaping the future of golf course maintenance. For more about how greens are built, read how golf greens are built.
