This invention relates to a horticulture additive comprising: (1) a wetting agent, wherein the wetting agent is a multi-branched polymer comprising at least one of an oxygen-containing and a nitrogen-containing polyfunctional base compound having at least three branches attached thereto, and (2) a humectant. The horticulture additive is advantageous for increasing plant survival of plants treated therewith when exposed to reduced watering conditions.

An assembly for protecting an area from sand drift accumulation comprises a sand berm having an exposed surface that is chemically stabilized using a stabilizing agent and a fence embedded in the exposed surface of the sand berm at an angle to vertical. The fence deflects wind flow directed toward the sand berm downwards, protecting the area downwind from sand drift accumulation.

A method of maintaining soil strength and stability involves positioning a sheet of soil stabilization and strengthening material on a selected area where the strengthening and stabilization of the soil is desired. The sheet of soil stabilization and strengthening material includes a fabric layer that forms a base of the soil stabilization and strengthening material. The lower surface of the fabric layer is positioned against and engages the selected area. A moisture impervious layer is coupled to the upper surface of the fabric layer. A particulate aggregate material is embedded in the moisture impervious layer.

Spray dried homogeneous mixtures of a high molecular mass flocculating agent, a base polymer dispersion, and a protective colloid are useful for homogenously stabilizing mixtures such as dust, sand, and/or soil and produce a stabilized composition of high strength.
