Soil moisture mapping protocol


My name is Chase Straw and I am a turfgrass scientist at the University of Minnesota.

I am contacting you because we have recently released a free soil moisture mapping protocol that can be utilized by golf course superintendents to assist them with fairway irrigation decisions. The protocol explains how to collect GPS soil moisture data with a commercially available device (FieldScout TDR 350), which are then used to generate fairway soil moisture maps with free software. The maps could be used as a tool to program an irrigation system to irrigate based on the soil moisture variability across a golf course, among possibly many other things. It is simple and easy to do, where anybody from a local high school golfer to the head superintendent can follow and complete it.

More information about the protocol, in addition to details regarding how the Minnesota Golf Course Superintendents Association of America chapter is utilizing it as a service to their members, can be read from a recent blog post on our UMN turfgrass website:

The protocol can be downloaded here:

The protocol requires a $0 licensing agreement. The reason for this is we want it to remain free and we also want to monitor who downloads and completes it for our own research purposes.

I kindly ask that you consider sharing this email and the link to download the protocol with your local GCSAA chapter(s) or other turfgrass association membership. Please let me know if you have any questions.


Thank you,
