The effects of alkalinity on physical and chemical properties of soil
Israel Zewd, Mira Siban
Although it is difficult to clearly separate soil functions into chemical,
physical, and biological processes because of its dynamic, interactive nature,
soil has certain chemical, physical and biological properties. Soils that are
significantly acidic or alkaline cover most of the land in the world. Soil
salinity affects plants directly through reduced osmotic potential of the soil
solution and the toxicity of specific ions such as boron, chloride, and
sodium. Soil alkalinity affects the physical and chemical properties of the
soil. Some adverse effects of alkalinity on soil physical properties are texture,
soil structure, soil color, Infiltration and Soil porosity, surface crusting, and
swelling factor. Effects of soil alkalinity on soil chemical properties include
soil pH and nutrient availability, Nutrient availability and alkalinity of soil.
Alkalinity of soil can be maintained by various methods to for successful
crops in alkali soils.
