This document provides guidelines for preparing and maintaining an infield mix and warning track for a baseball field. It recommends laser grading the base, saturating and compacting it before spreading the infield mix 2 to 3 inches deep. The mix should then be laser graded and optionally rolled for compaction. Weekly maintenance involves removing debris, dragging before and after games or practices, and nail dragging once a week. Yearly maintenance includes tilling and regrading the infield.
