Golf courses and lawns

Management of golf greens
The grass is cut lower than 5 mm, the roots are short and the soil sandy, making irrigation to be managed very careful. Golf courses open early in the year and closes as late as possible and then the temperature in the root zone very important to follow to know when cultivating actions benefit the plant rather than stress it. In summer reading the temperature and accessible moisture clearly shows if additional irrigation is needed during the day.

With sensors in the greens you can follow if irrigation, aerating, wetting agents, fertilizers etc have the intended effect and even dry spots can be predicted before they appear on the surface and actions become easier. Changes in the physical properties in the turf is shown as slower changes in soil moisture than earlier.

Soil moisture sensors are a quick and easy way to document and monitor golf greens.

A physical analysis of the golf green at the location where the sensors are placed increases the ability to interpret the data correctly. It is mainly percolation rate, particle distribution curve, organic content at different depths, total pore volume, pore volumes at field capacity and water holding capacity at field capacity which should be identified.

Function
The equipment consists of a base unit that connects to the soil moisture sensors (measuring tension in kPa) and temperature sensor, for placement on two levels in the green, in the plant bed and at a depth where the plant bed is capillary saturated at field capacity, often 10 or 25 cm deep.

The base unit should be located so that it is not in water. A measurement take place every hour (or more frequently) and uploads to the Internet via GSM network. They can then be viewed via computer or smart phone.

Deliverance
The equipment is sent as package against fee, or can be picked up in Lund, Sweden.

Deployment
Charge the batteries with the supplied USB cable in the base unit socket, or via an external battery.
You can use the sensors in a putting green that is representative for most other greens, or you may want to monitor a green troublesome to manage. Choose a location approximately three feet onto the green, which is flat and not subject to flowing surface water. Deploying sensors where you want to measure, pull the cables out to the green edge. Dig down an irrigation box, slit the grass, lay the cables and sensors. Put back the grass. In the box, mount the base unit pendant, so it will not be exposed to excess water in it.

Monthly cost
Subscriptions for data charges according to how often you want to measure. Default is once per day. If you wish to increase the frequency you prepay a sum which is then deducted by the frequency measurement is made. For a season, you can calculate with about 75 € per year.
The base unit will choose an operator that is available, which means high reliability, and that it will work in any country, most likely.

Internet service
Your measurements are shown on a website when you log on. You can name the sensors and the base unit. All measurement data can be exported to an Excel file for detailed analyzes. See our video tutorial on how to export sensors and create charts.
You can also set alarm levels for the various sensors that are connected. This will send an email and/or sms when the value are above or below your setting.
Examples of the presentations of measurements can be seen at our demonstration web.

Theft Protection
The base unit can be locked in the GSM operators theft records and then becomes useless to a thief. It can also be tracked geographically.
