Optimize Sports Turf Irrigation & Maintenance with Accurate Soil Data

optimize sports turf irrigation

The primary challenge in Sports Turf Irrigation, is: how to ensure a safe, durable, and high-quality playing field for the entire season while optimizing water consumption and maintenance costs?

The irrigation is often scheduled based on inaccurate data, which does not provide insights into infield soil variations. As a result, Turf Managers cannot achieve optimal turf conditions, water is wasted, and repeated maintenance activities increase costs.

There is an alternative – by using Underground Wireless Sensors; you can monitor soil moisture, salinity, and temperature in real-time in multiple spots, detect the infield soil variations and irrigate each part of your turf in an optimized way – saving costs, time, and water!

What’s the Main Challenge in Sports Turf Irrigation?

Lack of accurate underground soil data, which would also provide an insight into the infield soil variations, makes irrigation optimization difficult for Turf Managers.

The turf maintenance staff often use hand-held measurement instruments to collect soil data. However, poor repeatability of the exact measuring spots reduces the consistency of manually collected data. Further, collecting enough samples to compensate for this inconsistency, not to mention covering an entire field properly, becomes an excessively laborious task.

Automated irrigation is usually scheduled according to evapotranspiration (ET) models, which are unable to expose local differences such as uneven precipitation – let alone providing enough granularity to detect the infield variations in soil moisture.

How Unoptimized Irrigation Affects Turf?

Unfortunately, scheduling Turf Irrigation based on inadequate information causes several problems.


Under-watering a turf results in a hard field surface, which increases the risks of shin splints, and shoulder and knee injuries, and slows down turf growth. Increased salinity, on the other hand, reduces grassroots’ ability to take up water and nutrients.


On the contrary, over-irrigation intensifies unnecessary turf growth and results in lush turf, which doesn’t tolerate heavy use. Wet soil surface compacts quickly and the roots’ ability to access water deeper in the soil. Many weed problems emerge due to over-irrigation. Over-irrigation increases leaching of nutrients, and denitrification (nitrogen is lost into the air).

Unbalanced Irrigation

The ET-models cannot provide sufficient detail for detecting soil moisture variations between different parts of the field. Hence the irrigation is applied uniformly across the entire field – even though the parts exposed to most sun and wind would require more water compared to the areas which stay most time in the shade or receive more intense natural precipitation.

You end up wasting the maintenance budget on reactive care, rather than investing in proactive, long-term turf development!

Consequently, it is impossible to achieve optimal field conditions without accurate underground soil data. Instead, extra maintenance actions are required throughout the season. Consumption of fertilizers and water surfactants increases, much water is wasted in the process, and, consequently, you end up wasting the maintenance budget on reactive care, rather than doing proactive, long-term turf development.

The Solution: Optimize Sports Turf Irrigation with Underground Soil Sensors

The solution is underground soil monitoring using wireless sensors, which are easy to deploy and can measure moisture, salinity, and temperature in multiple spots at your turf in real-time. With the data provided by the underground sensors, you can determine precisely, which parts of the turf need to be treated, and when – and where do you need more sensors to support your agronomical problem assessment!

Why Should You Monitor the Infield Soil Variations?

With the underground sensors, you don’t have to settle for inaccurate information based on a single average moisture value for the entire field. Instead, you can place multiple underground sensors across your field in the locations you know are different by experience, monitor different parts of the field separately, and apply an individual management plan for each of them.

By capturing the infield variations in your field, you can apply the right site-specific maintenance activities, identify the optimal areas and replicate the conditions, eliminate quality variations, avoid unnecessary maintenance activities, and refocus your maintenance efforts and budget on more pressing issues and proactive turf development. So, by monitoring infield soil variations, you can avoid unbalanced irrigation!

The Benefits of Underground Soil Monitoring

When you monitor the soil quality below the field surface, you can avoid the problems of under-watering and over-irrigation. Here’s a rundown of the benefits:

  • Improve the field quality and minimize infield quality variations
  • Optimize the field hardness and minimize injuries
  • Increase the maintenance work efficiency
  • Reduce water consumption
  • Avoid leaching – use fertilizers more efficiently
  • Diminish the need for expensive water additives and surfactants
  • Optimize turf growth pace
  • Reduce reactive maintenance costs and invest in proactive development instead!

Driving Efficient Water Use at Desert Mountain

One thing is for certain as it pertains to golf course maintenance, and that is how we protect our most valuable natural resource – WATER.  With technology increasing at a rapid pace when it comes to how we manage our courses, we have found that by integrating the Soil Scout system into our daily routine, we are able to become more anticipatory rather than reactionary in our irrigation scheduling.  With the wireless sensors and real time information, we have become more precise in calculating the percentage gain or loss of moisture in the soil.

The Soil Scout allows us to see exactly what impact an irrigation cycle had on the moisture level and we are able to be more efficient in future scheduling by watching the data that we receive from the in ground sensors.  It does all that is says it can do and has shown to be another valuable tool in our efforts to produce high quality playing conditions while at the same time using  water wiser.
