Directly behind the rotating knives is a wedge-shaped stationary dagger that is positioned to line up inside each of the slits. This wedge is approximately 1 inch wide and acts to hold the slit open enough that sand can be automatically shaken by the machine into the trench. The sand holds the soil in place preventing the fractures and loosened soil from returning to their previous state of compaction and prevents the trench from closing. A local fi eld manager recently reported to a group of his peers that he documented 2 inches more root growth after micro-trenching his highly compacted soccer fi eld. Micro-trenching de-compacts the soil, holds water, yet allows excess water to flow off the field and allows play on the fi eld to begin sooner. It allows imperfections in the slope of the fi eld to drain and allows slow draining fi elds to drain faster. Technology details Smaller particles, like silt and clay, have greater relative surface when compared to the large sand particles in the trench. This gives the silt and clay a stronger capillary attraction to the water than the larger sand particles. Water that is held by the relatively large sand in the trenches begins to be pulled vertically and horizontally into the fi ner sand, silt and clay particles sportsturf_october2017_final.indd 1 9/11/17 2:10 PM • Protect turf from harsh winter conditions! • Promote faster spring growth and green-up! • 8 Year Limited Warranty • Heavy 100% woven polypro fabric • Reinforced hems and grommets all edges • Stakes stay in place & won't rip fabric Stakes keep covers in place in brass grommets at 5' intervals.
