Coir based soil less natural grass-instant lawn for soil erosion control

摘要

A lush green readymade lawn of grass has been developed. The lawn is encased in a composite comprising a single or multiple layers of non-woven coir fabric embedded in coir netting. A layer of coir pith is placed on the non-woven layer. Grass slips are planted on the coir pith bed so made and Coir Pith Organic Manure [CPOM] is sprinkled thereon to form a thin layer. Grass of choice can be grown to prepare the lawn. The ready to use lawn is made available in the form of blankets. It is easy to shift the material from one place to another and it can be rolled for transportation.The open weave structure of supporting fabric ensures complete drainage of excess water and helps in supporting roots of the planted grass saplings and protects bare surface otherwise vulnerable to erosion by rain and wind while grass develops to provide long-term protection. Typical applications include ground cover, roof cover, cycle path, footpaths, sand dunes and vegetation restoration in arid areas including rocky patches. It can be folded easily and fits to the contours of the location and creates a microclimate, which boosts plant development. It is recommended on sites where seeds are prone to be washed out.It is advantageous to use this lawn in place of grass turf as it is developed in a soil less and pesticide free medium. There is thus no unwanted competition with weeds requiring higher maintenance costs. As the coir pith is highly water absorbent and provides sustained release of micro and macro nutrients after conversion into organic manure by the application of an edible mushroom spawn, the lawn sustains for about 5 years. It does not pose any disposal problem as it is completely biodegradable unlike synthetic turfs.
