patent number 5617672
A method for controlling the growth rate of plants is provided. The method is directed to using a ureaformaldehyde foam composition blended with a soil formulation. Depending upon the amount of foam added to the soil, the resulting mixture can be used to selectively increase or decrease plant growth rates. The ureaformaldehyde foam can also be used to increase the germination rate of seeds and to increase the percentage of seeds that germinate.
