It will be cut with either a cylinder mower, or a rotary mower and all clippings will be let fly and returned to the surface.

  Amenity Turf Category F

This has a minimum height setting of a mower of 75mm and a maximum recommended height of vegetative growth of 150mm. This category of turf will typically cut every 3 to 4 weeks. It can be suitable for areas in water engineering, such as flood banks or in woodland settings or country parks. It will be cut with either a rotary mower, flail mower or reciprocating knife mower and all clippings will be let fly and returned to the surface. The desirable grass species will be quite varied depending on what is aiming to be achieved, so, any turfgrasses could be considered depending upon the situat

  Application Rate

A defined quantity and unit weight of material which is to be put on to a defined area. For example, 25 Kg per hectare, or 25 g per m².

  Application Rates, Factors Affecting

The quantity of material applied using a spreader (fertiliser or grass seed in particular) can and will vary according to a range of factors, including: • The forward speed at which the spreader is being used. A faster forward speed will reduce the quantity applied. • The size of the aperture setting into which material passes. A large aperture will allow for a greater flow of material. • The type and size of the material, with finer material typically having a higher bulk density than coarser material. • The condition of the material. Dry material is freer flowing than damp material, so e

  Approach

The area in front of a golf green which forms part of the fairway and is the direction in which a golfer would approach the green.
