Abstract
Methods for reducing or preventing topsoil erosion with hydrogels are described. Upon treatment, a plot of soil may exhibit improved water retention capacity, reduced topsoil erosion and improved aeration properties for plant growth.
Claims22
A method for reducing or preventing topsoil erosion, comprising:
- a) providing a powdered hydrogel, said powdered hydrogel comprising a first polymeric material hydrogen bonded to a second polymeric material, wherein said first polymeric material includes polyacrylic acid and said second polymeric material includes a polyglycol other than polyethylene glycol;
- b) applying said powdered hydrogel to a top surface of a plot of soil.
A method for reducing or preventing topsoil erosion, comprising:
- a) providing a powdered hydrogel, said powdered hydrogel comprising a first polymeric material hydrogen bonded to a second polymeric material, wherein said first polymeric material includes polyacrylic acid and said second polymeric material includes a polyglycol other than polyethylene glycol;
- b) mixing said hydrogel with water to form a liquid hydrogel;
- c) applying said liquid hydrogel to a top surface of a plot of soil.
