Method of promoting water transport through soil

A method of promoting and controlling the transport of water through medium and coarse grained soils comprising the step of applying to medium or coarse grained soil a soil amendment composition comprising a substantially linear, substantially water-soluble hydrophilic polymer of ethylene oxide having a molecular weight greater than 50,000, said composition when applied to said soil at various levels of at least 0.05 but less than 5 parts per million parts of dry soil displaying a well defined peak efficiency at a given level, said composition being applied to said soil at or about said given level.

A method of promoting and controlling the transport of water through medium and coarse grained soils comprising the step of applying to medium or coarse grained soil a soil amendment composition at a level of at least 0.05 but less than 20 parts per million parts by weight of dry soil, said composition comprising a substantially linear, substantially water-soluble hydrophilic unsubstituted polymer of ethylene oxide having a molecular weight greater than 50,000.
