A method of forming wood fibres for use in the production of a riding surface comprises feeding wood chips having a length, in the grain direction, of from 18 mm to 35 mm, to a milling machine adjusted to break the wood chips into wood fibres, the lengths of the fibres produced by the milling machine being substantially in accordance with the following percentages, by volume, of the total volume: -Wood fibre length Percentage of Total Fibre -0 mm-5 mm 10%-20% - 5 mm-15 mm 40%-55% -15 mm-35 mm 35%-50% - It is found that a surface formed from a compacted layer, several inches deep, of fibres produced by the above method has excellent characteristics for horse riding and these characteristics are not unduly affected by variations in weather conditions. |
