Soil conditioners may be used to improve water retention in dry, coarse soils which are not holding water well. The addition of organic material for instance can greatly improve the water retention abilities of sandy soils and they can be added to adjust the pH of the soil to meet the needs of specific plants or to make highly acidic or ...
Amelioration of soil structure leading to a reduction of mineralization by means of protecting soil organic carbon. Liming is known to ameliorate soil structure, as high Ca 2+ concentrations and high ionic strength in the soil solution enhance the flocculation of clay minerals and, in turn, form more stable soil aggregates.

However, marl was gradually replaced by lime and imported mineral fertilizers early in the 19th century. [23] A similar historical pattern was seen in Scotland. [21] Marl was one of a few soil amendments available in limited quantities in the southern United States, where soils were generally poor in nutrients, prior to about 1840. [24]
Soil conditioners are amendments that can be applied to the soil to improve properties such as structure and water retention to improve soils for their intended use, but not specifically for soil fertility, although many soil amendments can alter the soil fertility. Some typical amendments include: lime, gypsum, sulfur, compost, wood wastes ...
