Description
Summary:In view of soil structure analysis and land-use and management history evaluation, several mechanical indices of soil structure were tested on 13 Italian soils. From the wet and dry sieving aggregate distributions, a pseudo-textural aggregation index (Ipta) and a mechanical aggregation index (Ima)) were determined and compared with other soil structure stability indices based on single-sieve analysis. The single-sieve indices S and WSI were good correlated with Ipta and Ima, showing the possibility of substituting the time-consuming aggregate-size distribution determinations. All the soil structure indices were correlated with selected semi-permanent soil characteristics. Soil structural characteristics can be assessed with multiple-linear regression models using the semi-permanent soil matrix characteristics.
