Method of treating plant growth media with multi-branched wetting agents

摘要

Certain novel formulations of plant growth media additives that act in such a manner as to permit proper amounts of moisture to contact root systems in order to reduce hydrophobicity within said media. The inventive formulation comprising multi-branched surfactant compounds with both hydrophobic and hydrophilic constituents within each branch attached to a polyfunctional base compound permit effective moisture penetration through plant growth media for sustained seedling and plant growth therein. Such multi-branched wetting agents provide sustained moisture penetration over a sustained period of time, since the individual branches of such compounds may become dissociated from its base polyfunctional compound. Since such branches include both hydrophobic and hydrophilic constituents themselves, and thus act as wetting agents, even after degradation of the initial surfactant compound, repeated wetting and moisture penetration, at least, are permitted. Methods of treating plant growth media with such compounds and formulations thereof are also contemplated within this invention.

1. A method of reducing the hydrophobicity of plant growth media comprising the application of an additive formulation to the plant growth media, said additive formulation comprised of a multi-branched wetting agent having a polyol compound and at least three surfactant branches comprising alkylene oxide moieties attached thereto, wherein said polyol compound is sucrose, and wherein each surfactant branch includes both hydrophilic and hydrophobic constituents.
