The practice fields see activity pretty much every day. When the weather is wet it can get torn up pretty bad even if well maintained. I could see the stitched field being a huge benefit in keeping it playable with such heavy use. If you are adding it to the practice fields it seems like a no brainer to add to the stadium turf to help keep it pristine when you have back to back to back home games and the weather is being hard on it. I have been a fan of this and hoping ISu would get it since I saw something similar (Grassmaster) on the Lambeau field a decade or more ago.
One huge benefit of the stitched fields is that it adds stability to the sand substrate. Since these fields are built on pretty much straight sand, 300+ pound bodies pushing on each other can move the sand around under the grass resulting in an uneven playing surface over time. The stitching goes deeper than roots alone and also encourages the roots to go deeper adding stability to that substrate.
This is pretty spot on and I don't know how you would know this. The field isnt pure sand its a mix of peat and sand, but we are splitting hairs on that.
