Abstract
A process for preparing a polymeric membrane for soil materials used in crop production comprising providing an aqueous dispersion of polyurethane and spraying the aqueous dispersion onto soil materials to be used in crop production to form a polymeric membrane.
Claims18
A process for preparing a polymeric membrane for soil to be used in crop production, the process comprising:
- providing a sprayable aqueous dispersion of ionic polyurethane, wherein the aqueous dispersion further comprises a thickening agent;
- and
- spraying the aqueous dispersion onto an area of soil to be used in crop production from seeds or pre-grown plants to form a polymeric membrane on the surface of the area of soil, wherein the aqueous dispersion is sprayed onto the area of soil (i) prior to planting of the seeds in the area of soil, or (ii) prior to planting of the pre-grown plants in the area of soil, or (iii) after planting of the pre-grown plants in the area of soil.
