註釋"Sodic soils cover almost a third of the total land in Australia and are represented to some extent on all continents except Antarctica. They can occur naturally, as in Australia, or may develop as a result of the removal of salts from saline soils." "Sodicity impacts adversely on many soil properties and interferes with the proper functioning of the soil and of the plants grown in it. Problems arise as a result of the deterioration in soil structure, decreased retention and availability of water, decreased nutrient availability and impaired biological activity. Sodic soils are easily eroded and this causes severe land degradation and pollution of water resources." "The management of sodic soils is often difficult and challenging. Because they are so widespread in Australia, their impact on productivity is immense." "Australian Sodic Soils: Distribution, Properties and Management brings together for the first time the results of scientific studies carried out in Australia and presented at the first national conference on Australian sodic soils."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.
