Felt
Felt is an organic layer formed by living and dead sprouts, stems and roots, which develops between the green zone of vegetation and the soil surface. Felt accumulation starts when the turf produces organic waste faster than it can be decomposed.
The parts that resist decomposition most effectively - stem nodes, tops, vascular tissue fibres and roots - make up the felt mass.
Turf
Depending on the layer in the turf, the felt can have both beneficial and damaging effects. For example, a thin layer of felt in the lawn (½ inch or less) provides insulation against extreme temperatures and changes in soil moisture. In sports lawns (½ inch or so) it provides greater resilience and strength, softens the impact of players on the surface, and improves footing. However, if the turf has a felt layer of more than one-inch possible turf problems are likely to result.
