Soil conditioners are materials that measurably improve the physical characteristics of the soil as a plant growth medium. Typical uses include erosion control, prevention of surface sealing, and improvement of water infiltration and drainage. Many natural materials such as peat and gypsum are used alone or in combination with synthetics for soil conditioning. This article is concerned with uses of synthetic soil conditioners, primarily synthetic polyelectrolytes such as polyacrylamides, in agriculture, horticulture, and related applications.
