Irrigation of the soil with water charged with dispersed resin for the purpose of stabilizing it against its erosion is discussed in the present paper, as a method that is considered to be as effective as the commonly practised process of planting it with fast growing grass, and therefore as of promising utility.
The synthetic resin emulsion is denatured into the vein of aggregation of particles, and forms films when it is spread over the soil. It is found to be a superior soil stabilizer against its erosion, and superior also in drying time and in germination. If it is mixed, at the initial stage of the process, with hydrophilic synthetic resin sponge powder, it gains in stabilizing efficiency against soil erosion and also in germination.
Owing to this last mentioned virtue, this soil stabilizer against its erosion can function also, when it forms layers over the surface of the soil, as artificial cultivation medium, protecting the soil in cold weather from formation of subsoil icicles. It can thus be utilized for the fertilizing purpose to grow grass on the soil too against its erosion.
