A study on soil structure
As soils differ in capacity to form a structure, it is necessary to distinguish between intrinsic structure and actual structure. Intrinsic structure is the capacity of a soil to form a certain structure. Actual structure is the structure of the soil at a certain moment.Using experiments and published data, the factors that influence both structures were discussed. This study showed that it was necessary to distinguish between floc structure, microstructure and macrostructure as the successive states of aggregation. In soils with very low electrolyte content only microstructure and macrostructure could be distinguished.A review was given on methods of estimating soil structure in the field and laboratory. Apparent discrepancies in the results of methods of estimating the structure of a soil were explained.Finally water relations in soils with different structures were investigated with tensiometers.
