Managing Thatch in Lawns - Penn State Extension
Nov 10, 2016·Mower scalping is another significant problem in turf with thick thatch layers. Scalping results when mower wheels sink into thatch allowing the deck to ride on the turf, effectively lowering the height of cut. Also, the crowns of grass plants growing in the thatch layer tend to be elevated above the soil, making them more susceptible to scalping.Contact SupplierSend Email

Examples of Density for Substances & in Real Life
Examples of relative density, or different densities in different substances, occur throughout everyday life. In an oil spill in the ocean, the oil rises to the top because it is less dense than water, creating an oil slick on the surface of the ocean. A Styrofoam cup is less dense than a ceramic cup, so the Styrofoam cup will float in water ...Contact SupplierSend Email
Managing rough grassland - High Weald
Low density cattle grazing is often the best form of management. However it is important not to over-graze which would destroy the litter layer altogether. Topping the grass to a height of no less than 130mm every other year is an alternative method or small sites can be ‘topped’ using a brushcutter, strimmer or scythe.Contact SupplierSend Email
