Vegetation base soil and a method for growing vegetation on a sloped surface

Abstract

Slope surfaces of land can be eroded by rain and wind. It is necessary to vegetate a bared slope surface of land for the purpose of erosion control and environmental conservation. The present invention provides a vegetation base soil composition and a method of growing vegetation on a sloped surface for erosion control and vegetating on cut rock slope surface, such as weathered rock surface and barren soil surface. The vegetation base soil includes peat, bio-solids formed by the treatment of urban sewage, for example water treatment plant sediment, woodchip, bark, animal waste compost and clay or loam. The vegetation base soil with a microbes active material, a root activation fertilizer, an adhesive material and seeds are applied over a mesh that is secured over the sloped surface. Plants are grown in the layer of vegetation base soil.

 (a) about 5 to 35% weight percent of peat;   (b) about 10 to 39% weight percent of a sludge cake compost;   (c) about 10 to 40% weight percent of water treatment sediment that is dewatered;   (d) about 10 to 35% weight percent of an animal waste compost;   (e) about 10 to 30% weight percent of a wood chip compost;   (f) about 5 to 20% weight percent of a bark compost; and   (g) about 5 to 30% weight percent of clay or loam.
