Process for soil conditioning includes applying to the soil a composition comprising at least a water soluble or swellable polymer. The composition has a particulate form and is applied by an aerial application. The process is suitable for soil conditioning and for reduction in soil erosion in agriculture, forestry, construction and civil engineering, mining, water storage and transportation, protection of rivers and delta against pollution, environmental conservation.

One or more techniques and/or systems are disclosed for a bio-derived, environmentally friendly soil conditioner to facilitate the removal of overburden (also known as spoil) in tunneling and mining operations. The bio-derived, biodegradable, and non-toxic formula may be injectable into the soil-cutter interface, and can thicken the tunnel water and disperse the soil to improve the removal of the spoil. The biodegradable soil conditioner may comprise: 1) about 45% to about 75% triglyceride oil by weight; 2) about 20% to about 50% super absorbent polymer by weight; and 3) about 1% to about 4% surfactant by weight. Further, the biodegradable soil conditioner may comprise about 0.1% to about 1.0% viscosity thickening agent.

A sand stabilizer may be introduced into and applied in coarse, grained soils, and soils with low fines content. When a sand stabilizer is introduced into silty soils, sandy soils, and/or gravelly soils, the soils may turn into a mass linked with the sand stabilizer. This process can be undone as well. The sand stabilizer is a water-based polymer that may be formed of a plasticizer-free aqueous dispersion based on styrene and an acrylic acid ester (approximately 40-60%), an aqueous copolymer dispersion based on styrene acrylic (approximately 20-40%), dibutyl phthalate (approximately 4-8%), butyl cellosolve (approximately 4-8%), and propanoic acid, 2-methyl-, monoester with 2,2,4-trimethyl-1,3-pentanediol (approximately 4-8%). The sand stabilizer may be applied in the compaction with water and mixed. The sand stabilizer may be sprayed over a soil surface.

A modified superabsorbent polymer (SAP) comprises a SAP matrix and urea in the form of crystals that is integrated into the SAP matrix. The SAP matrix and the urea are interpenetrated. A method for producing the modified SAP may comprise a) preparing a mixture comprising at least one urea solution and at least one SAP, b) swelling the SAP in the mixture, c) crystallizing the urea in the mixture obtained upon completion of step b), d) recovering the modified SAP in the mixture, and e) optionally, forming the modified SAP recovered at step d).
