Clipping Intensity Impacts On Root Mass Variation Of Cool Season Grasses, D L. Stetson, W M. Sullivan
Clipping Intensity Impacts On Root Mass Variation Of Cool Season Grasses, D L. Stetson, W M. Sullivan
IGC Proceedings (1997-2023)
Seasonal changes in grass root and mat weight density were documented under different cutting managements. Kentucky bluegrass (Poa pratensis L.) and tall fescue (Festuca arundinacea Schreb.) received one annual cut, twice yearly forage harvest, and mown turf treatments. Orchardgrass (Dactylis glomerata L.) received one annual and twice yearly cutting treatments. Soil cores were collected to a 15 cm depth and divided into 7.5 cm increments. Roots and mat were recovered, washed, dried and weighed. Differences in years, seasons, species, treatments, and soil depth significantly influenced total root weight density and fine root density. With all species and …
