SOIL MODIFYING AGENT AND SOLID MODIFYING METHOD
To provide a soil modifying agent excellent in an effect for improving water permeability.SOLUTION: A soil modifying agent contains an aqueous resin emulsion and a water-soluble polymer. A content of the water-soluble polymer in the soil modifying agent is preferably 1-20 mass% in terms of a solid content. The aqueous resin emulsion preferably contains a structural unit derived from vinyl acetate, and is particularly preferably an ethylene-vinyl acetate vinyl copolymer emulsion. The soil modifying agent preferably dries the soil after having been sprayed to the soil, and preferably sprays thereto so that a solid content mass is 100-1,000 g/mand a spray liquid amount is 1.5 to 8 L/m.SELECTED DRAWING: None
【課題】透水性の改善効果に優れた土壌改質剤を提供する。【解決手段】水性樹脂エマルジョンと、水溶性高分子を含む、土壌改質剤。土壌改質剤中の水溶性高分子の含有量は、固形分換算で１〜２０質量％であることが好ましい。水性樹脂エマルジョンは、酢酸ビニルに由来する構造単位を含むものであることが好ましく、特に、エチレン−酢酸ビニル共重合体エマルジョンであることが好ましい。土壌改質剤は、土壌に散布した後に、当該土壌を乾燥させことが好ましく、固形分質量が１００〜１０００ｇ／ｍ２、散布液量が１．５〜８Ｌ／ｍ２となるように散布することが好ましい。【選択図】なし
