Infield testing gives you valuable information about the composition of your field. It tells you the percentages of important components—including sand, silt, and clay—and alerts you to unwanted materials in your mix.

Gravel is one such material you don’t want in your infield. Gravel content includes all material in the size range of 2 mm–12.5 mm. The ideal percentage of infield material in that range is less than 3%. 

Gravel includes small stones and even some sizes of conditioner. Infield mixes should be screened to remove gravel, but you can conduct an independent laboratory test to confirm that the material has been properly screened.

Continue to test your infield mix regularly to understand its composition and identify any problems to correct. Your ATS rep can help you interpret the results of your infield test and strategize accordingly.
