摘要： 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.
