Abstract from DBPedia
    Soil quality refers to the condition of soil based on the needs of human and non-human life. According to the United States Department of Agriculture Natural Resources Conservation Service, "Soil quality is the capacity of a specific kind of soil to function, within natural or managed ecosystem boundaries, to sustain plant and animal productivity, maintain or enhance water and air quality, and support human health and habitation." The European Commission's Joint Research Centre proposed a definition, stating that "Soil quality is an account of the soil's ability to provide ecosystem and social services through its capacities to perform its functions under changing conditions." Soil quality reflects how well a soil performs the functions of maintaining biodiversity and productivity, partitioning water and solute flow, filtering and buffering, nutrient cycling, and providing support for plants and other structures. Soil management has a major impact on soil quality. Soil quality in agricultural terms is measured on a scale of soil value (Bodenwertzahl) in Germany. Soil quality relates to soil functions. Unlike water or air, for which established standards have been set, soil quality is difficult to define or quantify. Soil quality can be evaluated using the Soil Management Assessment Framework.

    土壌改良(どじょうかいりょう)とは、耕作に不適な土壌を改良し、圃場の地力(生産力)を増進させるために、土地に資材を投入して土壌の理化学性および生物性を改良することである。 土壌改良のための資材を土壌改良材と呼ぶ。広義には土壌の性質に変化をもたらす資材全般を指し、水はけといった物理性を改善する客土材などのほか、酸性土壌を矯正する石灰と言った肥料に分類される資材も一部含む。元来は1950年代に開発された、団粒形成を促進する高分子資材のことを狭義に指したが、現在は意味合いが広がっている。1984年には地力増進法によって政令指定土壌改良資材が定められるようになり、1996年改正の同施行令では12品目が政令指定されている。
