Scientific research In Biology - Essay ExampleThe condition of high Soil sodium is referred to as sodic, and is super C in desert and arid lands. An example is the Yelarbon area of Australia. When the Chloride form dominates, it is referred to as saline. Salinity though whitethorn also refer to an change magnitude amount of the chlorides of Potassium, Magnesium and Calcium. Increased Sodium salinity often leads to sodicity.An overmuchness of the cation may lead to increased pH and increased soil osmotic pressure retarding the ability of plants to guide water. Furthermore, an increase in the Sodium Carbonate concentration leads to an ion exchange reaction that immobilizes Calcium. Calcium is an important governor of growth and development in plants. Its participation involves nearly all aspects of plant development. (Harper J.F, 2004)Another problem associated with increased soil Sodium is the toxicity to Na+ sensitive plants, and disruption of soil structure leading to crusting and miserable drainage. (Ruiz Vera, 2006). This reduces available soil oxygen as well. The receives of increased sodium may be man-made or natural. Irrigation of soil with water having increased sodium carbonate is one artificial method. A natural cause may be weathering of rocks containing Sodium carbonates. The control of sodicity is by improver of Calcium in form of Limestone, sulfur and drainage of the soils affected.If an increase in soil osmotic pressure leads to retarded growth of lawn grass, then addition of a proportional amount of salt to a control sample will lead
