Abstract
The present invention is directed to a method for increasing the wetting rate of a plant growth medium utilizing a wetting agent composition. The composition is comprised of at least one modified block copolymer. The modified block copolymer is comprised of an ester of an ethylene oxide-propylene oxide block copolymer and a fatty acid. The composition of the present invention also enhances plant growth and productivity by increasing the water uptake and the nutrient uptake by the plant roots.
Claims19
A method for increasing the wetting rate of a plant growth medium containing soil, the method comprising:
- contacting the plant growth medium with a wetting agent composition, the wetting agent composition comprising at least one modified block copolymer comprising an ester of an ethylene oxide-propylene oxide block copolymer and a fatty acid, wherein the ethylene oxide-propylene oxide block copolymer is represented by the formula
- wherein x, y, and z are integers having a value of 1 or more.
